Shengli Zhuangxi builds core technical advantages and enhances efficiency

Sinopec News Network News Since this year, the Zhuangxi Operation Area of ​​Shengli Oilfield Downhole Operation Center is based on the characteristics of Zhuangxi’s "Three Highs and One Low" "Geological Grand View Garden" reservoir, firmly establishing the concept of "Limited Resources and Unlimited Technology" to build the core Technical advantages, overcoming the high difficulty of Zhuangxi construction, improving the technical level of workover technology and workover capabilities, and ensuring the smooth operation of local oil and gas production
.

Create deep well and ultra-deep well workover technology
.

The operation area is equipped with complete deep well and ultra-deep workover auxiliary equipment and facilities, perfect workover technical standards, introduce and promote a series of tools for accident handling of deep wells with large casing and deep wells, and study the drilling, punching, casing and grinding technology of buried hill lost wells , Large-casing and deep-well open-hole salvage technology, formed a technical series, and occupied the internal market of the territory with brand technology

Create casing-damaged well treatment and workover technology
.

The operation area carried out the research and improvement of the technology of removing and replacing sleeves in the open hole, such as anti-jamming, well control, sleeve milling, and centralizing; carried out the integration of the cement consolidation section, innovated the process and methods; introduced and promoted the hydraulic shaping of the curved casing With the channel drilling technology, improve the success rate of curved casing channel drilling and workover time; promote the subsidy technology of solid expansion pipe, and improve the construction ability of casing damaged wells
