Three "integrations" help the development of difficult-to-use reserves in the Baima block

Recently, the Jiaoye 146-2HF well, which was drilled by the 70153JH team of the Second Drilling Company, was successfully completed.
For the first time, it realized one-trip drilling, one-trip drilling, and two-trip drilling of the pilot hole in the Baima block.
The "1122" technical goal of drilling in three trips and two trips once again accumulated valuable experience for the efficient exploration and development of shale gas in the Baima block
.

The Baima block in the Fuling industrial area is a production base for Party A to build a replacement position of 100 billion reserves and a production capacity of 1 billion cubic meters.
It is also a model platform for exploring the new management model of cooperation and win-win cooperation between oil companies and engineering companies under the low oil price situation
.

Adhere to "integrated" collaboration

Establish the concept of “reducing costs, increasing efficiency, benefits, and developing a community” with Party A, aiming at the Baima block is an atmospheric shale gas reservoir with complex geological structure, and communicates with Party A’s engineering and geological personnel at multiple levels, channels and directions From the perspective of Party A, to improve construction efficiency, shorten the drilling cycle, and meet the requirements of the "four mentions" work
.

The premise is to ensure the development process, comprehensively evaluate and consider engineering geological factors, and integrate the design and construction plan to avoid unilateral consideration of single wells and other conditions that affect the overall construction effect
.

Implement "integrated" construction

In the process of well construction, comprehensive consideration of geology, engineering, drilling fluids, and directional construction factors, and rejecting "single fight", formed the most targeted and applicable construction plan
.

　　Each of the three openings in the Baima block needs to pass through more than 10 different stratums, and the construction requirements are extremely high
.

　　Carry out "integration" research

　　In response to the requirements of the exploration and development of the Baima block, work hard on the application of new technologies and new processes, and carry out joint public relations with service providers or scientific research institutions to solve construction bottlenecks and solve construction problems
.

　　The Baima block has complex geology and severe wear of drill bits and screws.
We have jointly developed drill bits and screw speed tools with the machinery company, established a technical research team, established technical research projects, and developed personalized drill bits to greatly increase the mechanical drilling speed and reduce the number of trips.
The drilling time and the drilling cycle have been greatly shortened.
The average drilling cycle of the nearly completed 8 wells has been reduced from 90 days to less than 50 days, and the reduction rate has reached more than 40%
.

　　In order to solve the difficult problem of the long horizontal section of the Baima block, through joint research and development with Yangtze University, hundreds of water-based and oil-based mud field tests and chemical comparisons have been carried out, forming a technical sequence of drilling fluids for shale gas wells in the Baima block In accordance with the recommended practice, the drilled Jiaoye 146-2HF well, for the first time, achieved the "1122" technical goal of the Baima block, and exceeded the "four-ups and one-down" mission requirements, which accelerated the pace of Party A's increase in reserves and production
