Research status and development suggestions of sidewall coring technology
摘要
Abstract
The sidewall coring technology is a remedial technical method for oil and gas reservoir evaluation and resource exploration.Its development has spanned nearly a century,gradually evolving from the early impact coring to the high-efficiency and precise rotary sidewall coring technology.This paper systematically reviews the evolution of the sidewall coring technology,focusing on the research progress and key technological breakthroughs of the rotary technology at home and abroad.By comparing and analyzing the technical parameters and application cases of international oilfield service giants and domestic enterprises,it reveals that foreign countries have a leading edge in aspects such as core size,temperature and pressure resistance,fluid-sealing sampling,and core digital processing.Although domestic enterprises have made remarkable progress in mechanical structure optimization,electric direct-drive technology,and temperature-resistant performance,there are still gaps in instrument reliability,adaptability to complex formations,and intelligence level.Based on the current technical bottlenecks and combining with the exploration needs of deep-earth and deep-sea areas,this paper proposes the future research and development directions of sidewall coring.The research results aim to promote the upgrading of Chinese sidewall coring technology towards high-efficiency,intelligence,and digitization,providing key technical support for ultra-deep well and unconventional oil and gas exploration.关键词
