Refined transformation of Northwest Oilfield facilitates efficient development of Shunbei

Sinopec News Network reported in the first half of this year, the Shunbei High-Efficiency Reconstruction Team of the Petroleum Engineering Technology Research Institute of Northwest Oilfield Branch aimed at the transformation of the Shunbei ultra-deep and ultra-high temperature complex fault-dissolved reservoirs, through the application of geological engineering integration targeted optimization design and establishment Shunbei reservoir reconstruction technology selection standards, introduction of wellbore stethoscopes to accurately detect temporary plugging segments and other refined reconstruction measures, the success rate of Shunbei new well reconstruction has increased to a record high of 89%, and the average single well production has increased by 130% over the same period of the previous year.

The whole process is integrated and targeted optimization design

In the past, when the new well was drilled to the target layer, the acid fracturing designer would collect data and carry out the acid fracturing construction design.

Through the docking with the research institute to clarify the transformation target orientation and the organic communication of the integration of drilling and completion within the project, more than 10 newly deployed wells were optimized in the whole process, which greatly improved the efficiency and quality of acid fracturing construction design and ensured the later stage.

Establish process optimization standards and standardize design

Aiming at the reconstruction of Shunbei ultra-deep, ultra-high temperature and complex fault-solution reservoirs, lack of technical standards, and insufficient design specifications, we summarized the data of different structural positions, reflection characteristics, drilling losses, logging interpretation, and in-situ stress characteristics, combined with geological engineering Integrated understanding, research and formation of Shunbei reservoir reconstruction technology selection criteria

Wellbore stethoscope technology successfully monitors the temporary blockage segment

In the past, when implementing the temporary plugging staged acid fracturing process, only the pressure rise during on-site construction was used to judge whether the temporary plugging was successful or not.

The Institute of Petroleum Engineering Technology will continue to thoroughly implement the deployment of oilfield companies to build tens of millions of large oil and gas fields, and actively practice the concept of geological engineering integration.
