井下增压超高压射流钻井技术研究进展
Research progress on ultra-high pressure jet drilling by down-hole pressure boost
摘要
Abstract
Oil and gas exploration and development is gradually shifting from shallow to deep formations, while the drilling of deep and ultra-deep wells confronts with problems of slow drilling rate and high cost. Research and experiment indicate that ultra-high pressure jet drilling is an effective technology to improve drilling rate for deep and ultra-deep wells, and down-hole booster is the key equipment for realizing ultra-high pressure water jet. Investigation of domestic and foreign literatures has revealed down-hole booster technique and pressure boosting mechanism, as well as the research progress in ultra-high pressure water jet assisted rock breaking mechanism; points out the disadvantages of previous researches, and suggests the direction of further research.关键词
