Fuling gas field set two new perforation construction records

On November 23, two gas wells on platform 147 of Jiaoshale in Fuling Shale Gas Field of Jianghan Oilfield successfully completed the first section of the traction perforation, with a construction qualification rate of 100%, respectively, breaking the two gas field engineering records of the deepest perforated construction well of 7006 meters and the longest horizontal traction distance of 2685 meters, laying a solid technical foundation
for the efficient transformation of deep and ultra-deep shale reservoirs in the gas field.

Jiaozhai 147-2HF well and Jiaozhai 147-3HF well are two key development wells located in Baima block of gas field, which face construction difficulties such as large well depth, long vertical depth and high risk
.
Fuling Shale Gas Company jointly established an expert support team to customize supporting construction plans and emergency plans
for the two wells.
During the construction, the safety measures were strictly implemented, the production was carefully organized, the construction nodes were accurately controlled, the perforation ignition was 100% successful, the perforation launch success rate reached 100%, and the first section of the perforation construction task
of the two wells was completed safely and high-quality.

It is understood that the tractor perforation technology is a new technology that uses the tractor to transport the perforating gun string to the bottom of the well and complete the perforation construction, which can smoothly realize the remedial construction of the first section of shale gas horizontal well perforation and downhole accidents, compared with the continuous tubing transmission perforation technology, this technology has the advantages of high timeliness, high precision, strong reliability, low cost and low safety risk, and has a wide range of application prospects
