Key Process Technologies and Prospects for Oil and Gas Testing in Sinopec's Deep Geological Engineering

In recent years, in view of the complex conditions of "deep geological engineering" structures and reservoir media, deep burial, high formation pressure and temperature, Sinopec has carried out key research on technologies such as deep and ultra deep oil and gas testing, ultra-high temperature and high pressure downhole tools, surface testing, narrow safety window oil and gas well testing engineering design and well completion testing fluid, successfully completed the testing construction of more than 100 oil and gas wells with a depth of 8000 m, initially formed the key technologies and supporting equipment for "deep geological engineering" oil and gas testing, which strongly supported the exploration and production of deep and ultra deep oil and gas resources in the Tarim Basin, Sichuan Basin and the Junggar Basin. An overview and analysis of the challenges faced by Sinopec's key technologies for oil and gas testing in the "deep geological engineering" were presented. Technical prospects were put forward for the design of ultra-deep high-temperature and high-pressure oil and gas testing engineering, ultra-deep high-temperature and high-pressure oil and gas testing completion technology, ground automation testing, and high-performance oil and gas testing tools. So as to build a more mature, professional, safe, and efficient oil and gas testing technology system to help achieve greater breakthroughs in deep and ultra deep oil and gas reservoir exploration and development.
