Recently, the group successfully applied perforation technology and continuous tubing bridge shooting technology in a certain unconventional oil and gas block in China, completing a one-time operation of 7-layer bridge plug setting and selective perforation. This is a major success of the groups recent updates and upgrades on the basis of the TCP electronic delayed perforation technology for cable bridge shooting. This move marks that the group has fully mastered and possessed the ability to apply this cutting-edge technology, accumulating valuable practical experience for the subsequent large-scale application of the group in similar oil and gas fields in China.

The conditions of the construction well are complex, the construction process is complicated, and the safety risk is extremely high. The cable bridge shooting and joint operation process can no longer carry out safe construction operations. The continuous oil pipe bridge shooting joint technology is an innovative technology that integrates the continuous oil pipe pressurized operation with processes such as bridge plug sealing and selection of launch holes.

In this assignment, relying on the excellent pressure operation capability of continuous tubing and advanced electronic delay bridge shooting coupling tools, the operation team achieved:

·Efficient and precise

One trip of the tubing string can complete bridge plug sealing and multi cluster selective perforation, changing the traditional process of delayed perforation with partition and sand filling fracturing currently used in the industry. The entire 7-layer operation of the well is completed in one go, greatly reducing operation time and improving construction efficiency.

·Safe and reliable

The entire process does not require repeated lifting and lowering of the tubing string, significantly reducing well control risks and personnel labor intensity, and comprehensively improving safety assurance capabilities.

·Reduce costs

Shortening the homework cycle, improving homework efficiency, effectively reducing comprehensive operating costs, and achieving significant economic benefits.

The successful application of the continuous tubing bridge injection technology is a major milestone in the domestic oil and gas field bridge injection operation technology, marking a new stage of more efficient, safer, and more economical development of unconventional oil and gas resources. It will provide strong technical support for promoting oil and gas production and storage in China, and ensuring national energy security.
