中国石油网消息：4月23日记者获悉，宝石管业自主研发生产的高端特殊螺纹套管，在渝西大安区块8000米级页岩气超深井成功应用，创下中国石油高端油气用管入井深度、水平段长度两项新纪录，标志着我国深层页岩气开发关键管材技术实现新跨越。

China Petroleum News: On April 23rd, a reporter learned that the high-end special threaded casing independently developed by Gemstone Pipe Industry has been successfully applied in an 8,000-meter deep shale gas ultra-deep well in the Dahan block of Chongqing West. This achievement has set new records for the depth of entry into the well and the length of the horizontal section for high-end oil and gas pipes in China Petroleum. It marks a new breakthrough in key pipe material technology for deep shale gas development in China.

此次投入使用的直径139.7毫米、壁厚12.7毫米的特殊螺纹套管，助力渝西大安区块一井完成8000米级超深下井作业。宝石管业这款自主知识产权产品，凭借优异的气密封性能、高强度结构与良好的现场适配性等多重优势，打破了高端油气用管在深层非常规油气开发领域的应用瓶颈。

The special threaded casing with a diameter of 139.7 millimeters and a wall thickness of 12.7 millimeters, which was put into use this time, assisted in completing the 8,000-meter deep well operation in one well of the Dahan block in the western Chongqing area. This product, with its independent intellectual property rights, boasts excellent gas sealing performance, high strength structure and good on-site adaptability, among other advantages, and has broken the application bottleneck of high-end oil and gas tubing in the deep unconventional oil and gas development field.

作业期间，宝石管业技术服务团队全程驻场值守，精准把控套管入井全流程，从质量复核到下井管控，对每一个环节严格把关，高效完成全部套管下井作业，后续相关工序一次性达标，保障了超深井作业安全高效推进。

During the operation period, the technical service team of Gemstone Pipeline Company was on-site throughout the process, precisely controlling the entire process of casing insertion into the well, from quality review to well entry management. They strictly controlled every step and efficiently completed all casing insertion operations. Subsequent related processes were also achieved in one go, ensuring the safe and efficient progress of the ultra-deep well operation.

此次成功应用，不仅是宝石管业高端管材研发制造能力的有力印证，更为我国深层页岩气超深井规模化开发提供了可靠的装备支撑。

This successful application not only serves as a strong evidence of the high-end pipe material research and manufacturing capabilities of the gemstone pipe industry, but also provides reliable equipment support for the large-scale development of ultra-deep wells in deep shale gas fields in China.
