Binnan Oil Production Plant vigorously promotes the production capacity construction model of "well factory"

Sinopec News Network reported that the oilfields under the jurisdiction of Binnan Oil Production Plant in Shengli Oilfield have been developed for more than half a century, and have generally entered the stage of high water-cut development, facing problems such as accelerated natural decline, insufficient resource replacement, and difficulty in stabilizing production.

Since the "13th Five-Year Plan", in the face of increasingly severe production and operation situations, the plant has insisted on unswervingly leading value, making every effort to promote production to focus on development, to pay equal attention to management and operation, and to transform resources to capital, and strive to maximize the value of oil reservoir management.

At present, the plant is insisting on the goal of "an annual output of 2 million tons and a break-even point below 40 US dollars per barrel".

Find more "vegetables" to enrich the basket

In order to ensure the drilling effect of the new well of the Bin 674 Expansion Project, Chen Lei, deputy director of the Institute of Geology, led the technical staff to keep an eye on the site for a month and a half, and summarized the formation of the "1+2+3" subdivision card layer method to improve the card of special lithology Layer accuracy to ensure the quality of drilling.

For an old oil production plant to achieve profitable output growth year after year, the need for reserve high-quality resources is even more urgent.

In order to promote high-quality exploration, the plant insists on emancipating the mind and changing concepts, jumping out of Binnan to look for "Binnan", under Binnan to look for "Binnan", and inside Binnan to look for "Binnan", and continue to fight for the pre-exploration attack in the new area , Rolling evaluation of positional warfare, and protracted warfare in old areas, and continuously improve the discovery rate of high-quality reserves.

They explored the management model of the rolling exploration project team, set up a new well measure well creation award, and cooperated with the Oilfield Exploration and Development Research Institute to carry out production and research cooperation and strengthen basic exploration research.

On this basis, they carried out rolling evaluations around medium-shallow, medium-high permeability, high-quality and high-efficiency reserves in accordance with the ideas of scale-driven, high-quality, and transformational development, and actively carried out the re-examination of well locations in the blank zone of the strata and the joints of the blocks.

　　In the operation of exploratory wells, they emphasized zone research, fine deployment, design optimization and node operation, refined quality control of each link in the whole process of drilling, logging, and logging, and strictly controlled the cost of reserve discovery.

　　Since 2020, the plant has completed 8 exploration wells with a success rate of 87.

　　Everything in the basket is "vegetable"

　　A few days ago, thanks to the optimization of the source of the plan and the integration of operation, the drilling construction of the Li 853 "Well Factory", which deployed 36 wells, was successfully completed, saving a total of 559 days of drilling time, and the qualification rate of all quality indicators reached 100%.

　　Since the "Thirteenth Five-Year Plan", Binnan Oil Production Plant has continuously strengthened its low oil price thinking, shifted from reservoir development management to reservoir operation management, and production capacity construction has shifted from large-scale production to high-efficiency production.

　　Schematic design is the total source of complete cost.

　　The plant focuses on the goal of "reducing investment and maximizing benefits", focusing on increasing economically recoverable reserves, making overall considerations, and operating in an integrated manner, doing everything possible to reduce the equilibrium oil price to ensure high-quality and high-efficiency increments.

　　In order to improve the quality and efficiency of capacity construction, while passing the "screen" of benefits, strengthening plan optimization, and intensifying assessment, they are problem-oriented, sorting out 85 production capacity construction business process nodes, optimizing 21 "parallel" nodes, and breaking "Relay" operation, realize "parallel" operation, and make every effort to accelerate the pace of construction.

　　They vigorously promote the "well factory" capacity construction model, innovate and optimize the drilling design, operation procedures and oil production methods, effectively shorten the drilling cycle, and increase the production time rate and labor productivity.

　　Take care of every "vegetable" in the basket

　　In recent years, in response to the low-permeability, thick, and sensitive development problems of the inefficient block Zheng 408, Binnan Oil Production Plant integrated complex wellbore treatment, hydraulic sand and oil extraction and other technologies to implement comprehensive treatment, achieving a daily oil increase of 54 tons and an increase in oil production speed.
0.
48 percentage points, the recovery rate increased by 5.
1 percentage points, and the economically recoverable reserves increased by 186,000 tons.

　　Since the "Thirteenth Five-Year Plan", in the face of the continuous reduction of high-quality replacement resources, the factory has strengthened the concept of "Each unit has room for creating benefits, each unit can create benefits, and each unit must create benefits", and manage it well.
Every "vegetable" in the basket promotes the quality and efficiency of the stock.

　　Based on the principles of overall deployment, benefit priority, step-by-step implementation, and orderly advancement, they have managed 11 inefficient units in the past 3 years, covering more than 24 million tons of geological reserves, increasing economically recoverable reserves by 1.
3 million tons, and unit development benefits are obvious Promote.

　　The plant adheres to the development concept of “equal emphasis on oil and water, and water first”, optimizes the workload of water wells, water injection technology and cost direction, establishes injection water quality and subdivision water injection standards for different types of reservoirs, and strengthens the application of new technologies to correspond to injection and production.
The rate, split injection rate, and interval qualification rate were increased by 4.
6, 7.
3, and 5.
6 percentage points respectively compared with 2015.
The effective daily water injection increased by 7,450 cubic meters, which restored the formation energy and consolidated the long-term foundation of reservoir operation.
The natural decline rate fell by 2.
1 percentage points.

　　In terms of heavy oil production, the plant strengthened the optimization of steam injection parameters, promoted short-radius steam injection, strengthened the application of mature technology such as steam flow field adjustment, stratified steam injection, and increased the promotion of chemical cold production technology.
The oil-steam ratio increased by 0.
09 compared to 2015.
, The efficiency of heavy oil is effectively improved.

　　Regarding the treatment of long-stop wells, the plant has established the concept of “helping a long-stopping well means a new well with low investment”.
Since the 13th Five-Year Plan, a total of 357 wells have been shut down and more than 13 million tons of water flooding reserves have been restored.
