Research and Application of 245 MPa Ultra-High Pressure Perforating Technology

With the continuous vertical development of oil exploration and development, the depth of deep and ultra-deep oil and gas gradually increases from 8000 m to 9000 m, and the number of ultra-high temperature and ultra-high pressure wells is also increasing continuously. The pressure of perforating construction has exceeded 210 MPa, but the highest pressure rating of existing perforating equipment at home and abroad is 210 MPa. So, through the research of type 89 245 MPa ultra-high pressure perforating equipment, a set of perforating equipment with a pressure up to 245 MPa, including perforating guns, perforating bullets, detonating equipment, and shock absorber, has been researched and developed, and the 245 MPa ultra-high pressure perforating technology has been perfected. The on-site test results indicate that this technology is safe and reliable, and can meet the technical requirements of ultra-deep well perforating operations, promoting the development of ultra-deep well oil testing technology.
