China Petroleum Network News (Reporter Chen Qing) Through special research, the pipeline deformation control technology for complex fractured horizontal wells independently developed by the Petroleum Pipeline Engineering Technology Research Institute has made a substantial breakthrough.

In order to maximize resources, unconventional oil and gas wells generally adopt long-distance horizontal well groups and are developed through multi-stage hydraulic volume fracturing.

“Casing change is the key model of casing damaged wells in my country in recent years, and geological migration is the key factor.

Funded by the "13th Five-Year" National Oil and Gas Project, PetroChina Scientific and Technological Research Project, and the Shaanxi Provincial Science Foundation, the Institute of Management Innovation has carried out an innovative "geology-engineering-pipe string" integrated research, independently designed and developed the world's first set of unconventional The simulation test equipment of oil and gas wellbore working conditions provides a key means for the simulation test of complex fractured wellbore.

Since 2019, with the strong support of Chuanqing Drilling and Southwest Oil and Gas Field, the new technology has completed the first batch of three well engineering tests.
