Jianghan Oilfield: The core technology system of the "12th Congress" supports high-quality development

"On December 9, our institute held the annual achievement review meeting of the twelve core technology systems, and the review team composed of experts from our institute and relevant functional departments of the oilfield conducted a systematic review of the technological innovation progress, on-site application and intellectual property construction achievements of each technical system, summarizing experience and analyzing shortcomings, laying a solid foundation
for next year's scientific and technological innovation work.
" Zou Wei, director of the science and technology management department of the Jianghan Oilfield Research Institute, said
.

Since the beginning of this year, Jianghan Oilfield Research Institute has focused on the strategic goal of "thousands and thousands" of oilfield, played the role of "staff department" and "think tank", strengthened the construction of core technology system, formed an iterative and updated "twelve major" core technology system, and improved the level
of scientific research and production.
Up to now, relying on the construction of core technology system, it has led or participated in the formulation of 3 national standards, 11 first-class enterprise standards for the energy industry and Sinopec, and 15 authorized invention patents
.

Build a technical system and dynamically iterative update

"In 2012, we initially formed the thick reservoir compartment fine description technology, which is a sub-technology of the high-efficiency development technology system of low-permeability tight reservoirs, one of the twelve core technology
systems.
In April this year, a new method for describing unstable interlayers in huge thick reservoirs relying on geological modeling technology was explored, which achieved a more accurate depiction of interlayers, and this sub-technology was updated and improved
.
Yin Bo, an oil development expert at the research institute, said
.

In recent years, in order to further promote the construction of the core technology system of the institute and provide innovative impetus for the high-quality development of the oilfield, in October 2021, the institute launched the construction of the core technology system, systematically sorted out and summarized the technical system in the field of oil and gas exploration and development, and in March 2022, the twelve core technology systems
of dynamic iterative update were fully completed.

Zou Wei introduced that the core technology system of the institute includes three parts
: research and development, ongoing research and development, and technology to be developed.
The developed technology is the formed technology summarized to guide the exploration and development of new development blocks of the oilfield; Positive research and development technology is the technology needed to tackle the oilfield now and promote scientific research breakthroughs; The technology to be developed is to reserve the strategic development of the oilfield, and achieve the research and development goal
by creating scientific research projects and applying for outsourcing forces.

"Each core technology system contains 2-3 technology series, and each series contains several sub-technologies
that have been developed, are under development and are to be developed.
For example, the 'Efficient Seismic Data Collection Technology System under Double Complex Conditions' contains 2 technical series and 19 sub-technologies, of which 10 have been researched, 3 are under research and 6 are to be studied
.
At present, we are working on these 6 technologies
to be developed.
Zou Wei said
.

Establish a management system and give play to the role of talents

"At the beginning of this year, the hospital formulated relevant management measures, set up special awards, incorporated the construction of technical systems into the annual performance appraisal, and the performance weight accounted for 10%, and rewards and punishments were honored according to the assessment results, which promoted the greater role of experts
.
" Inbo said
.

In January 2022, the Institute issued relevant management regulations, the core technology system is coordinated and managed by the main leaders of the Institute, and the Science and Technology Committee, professional committees and research institutes are responsible for comprehensive operation, mainly implementing the relevant systems of the state, Sinopec and Jianghan Oilfield, promoting technology research and development, and inspecting the implementation of
evaluation.

"Each core technology system is led by experts, and each research institute selects technical backbones, forms teams, and promotes technology research and development
.
Carry out joint operations of large corps, form an integrated operation mode of scientific research and production, geophysical exploration and geology, and a mechanism for cross-integration of specialties and overall coordinated operations, and concentrate on tackling practical problems
in work.
Zou Wei said
.

At present, the fine characterization of residual gas has become the bottleneck restricting the enhanced recovery rate of Fuling shale gas field, so the institute selected 13 outstanding scientific researchers from different professional fields to form a shale gas modeling digital-analog integration innovation team, giving full play to the institutional advantages of "specialization in division of labor and cooperation integration", and realized the visualization
of the remaining shale gas three-dimensional distribution for the first time 。 Jiang Yuling, the youngest member of the team, said: "Under the constraints and norms of the management system, I can participate in the project operation and technical system construction more and faster, after joining the team, I completed the first residual gas target design and development scheme in China with the team, and represented the team to participate in the third 'Craftsman Cup' competition in the oilfield and won the first prize
.
" ”

"Since the beginning of this year, relying on the construction of the core technology system, 8 young people have been effectively guided to win awards in the 2022 Young Oilfield Oil and Gas Reservoir Development Dynamic Analysis Competition, and 11 employees have been rated as Jianghan Oilfield 2022 Science and Technology Stars, the best results
in history.
" Zou Wei said
.

Provide technical support around the actual production

"There is no successful
development of a single set of shale with a large thickness and no obvious compartments and a significant increase in oil recovery.
We have tackled and formed the sub-technology under the efficient development technology system of marine shale gas-the precise targeting design of shale residual gas, and created the first new model of three-layer three-dimensional development of shale in China, laying a solid foundation
for greatly improving shale gas recovery.
Liu Li, director of the institute's natural gas development institute, said
.

The core technology system of the institute focuses on the major needs of oilfield scientific research, production and development strategy, corresponds to the strategic goal of "thousands and thousands" of oilfield, and divides the core technology system into different target categories
.
"The high-efficiency exploration and development technology system of marine shale gas is decomposed into two major technical categories of efficient exploration and efficient development around the goal of 'trillion cubic meters of reserves and tens of billions of square meters of production' in the oilfield, and has achieved remarkable results in production forecasting, providing strong technical support
for the construction of 10 million tons of oilfield.
" Liu Li said
.

In the process of efficiently promoting the three-dimensional development of Fuling shale gas, the high-efficiency exploration and development technology system of marine shale gas is based on the development idea of "eating dry and extracting net resources and focusing on improving the two rates", with the goal of supporting the oilfield "improving recovery in old areas and building production in new areas", strengthening the key technology research of modeling digital and analog integration of residual gas fine evaluation, breaking through the "stuck neck" technology of efficient shale development, realizing the quantitative evaluation and three-dimensional visualization display of residual gas layering, and the expected recovery rate of the well group is 50%, reaching the international
。

"Under the guidance of the deployment of the core technology system, the institute has established 8 scientific research projects of Xinli Joint Stock Company this year, 16 scientific research projects of branch companies, 8 pilot projects of joint stock companies, and carried out 21 foreign technical collaborations, with a success rate of more than 90%, which has accurately guided the scientific research and production work
of the institute.
