Petrochemical Jingwei Pingqiao 101 Well Perforating Construction Sets National Record

Sinopec News Network News on August 3, Petrochemical Jingwei Jianghan Logging and Logging Branch successfully completed the perforation task of Pingqiao 101 well, creating a single well with the longest perforation span of 1601 meters and the number of tubing transmission perforation clusters up to 15 clusters.
Tubing There are 3 national construction records including the maximum number of transmission perforation initiation levels of 30
.

Over the years, the company has continued to carry out multi-stage perforation technology research, forming high-temperature and high-pressure wells/highly deviated well pumping, horizontal well multi-stage directional fixed-surface perforation, casing-in-consolidation repeated fracturing multi-stage perforation, etc.
18 This core technology realizes the comprehensive localization of ground, underground, pyrotechnic equipment and tools, and is the domestically most capable, large-scale, and best-service perforating construction force
.

Well Pingqiao 101 is a key exploratory well deployed in Nanchuan, Chongqing.
The design requires the use of tubing transmission perforation technology and one pipe string to complete the perforation task of 15 clusters in 8 sections of the entire horizontal section.
The perforation section has a span of 1601 meters, which is not available in China.
The successful case of such a large-span perforation construction has many risks such as excessively heavy pipe string dropping, multi-cluster initiation and blasting, repairing well control, etc.
, and the construction is extremely difficult
.

Jianghan Logging Company attaches great importance to it, has organized technical personnel to discuss construction plans for many times, and finally decided to use tubing instead of interlayer gun, adopting the process of "simultaneous ignition, graded delay, double initiation", and specially made reinforced 60-ton alloy pallets and 80 tons of alloy lifting pup joints
.

From July 29 to August 3, multi-level perforating professional cadres stationed in the well to ensure the safety and quality of the construction; the JH-SK012 team undertook the task to overcome the difficulties of the hot sun and high-intensity continuous operation, and strictly follow the design plan for fine construction the successful completion of the task perforation, once the ignition success rate of 100% and the emission rate of 100%, and create three national construction records, obtain Party praise
.

　　The high-quality completion of the perforation construction in Pingqiao 101 well has successfully explored a new set of perforation technology for shale gas development in the Pingqiao block, further enhancing the brand image of "Jianghan Multi-stage Perforation"
