摘要
针对川渝地区高含H2S和中含CO2气田特点,并结合国内外高含硫气田开发情况,分析认为:除油气勘探开发本身的高隐蔽和高风险外,其高风险还突出表现在H2S和CO2带来的强腐蚀性和剧毒性两个方面。这些风险又主要集中在钻、完井(包括修井)两个主要环节上。在此基础上分析并提出了川渝地区高含硫气田钻、完井主要六个方面难点和八个方面对策。
According to the features of high sour gas field and CO2 gas field in Chuan-Yu area,and in communication with the development status of high sour gas field at home and abroad,it is known as the high risk of drilling operation in sour and CO2 gas field consist in the strong corrosivity and acute toxicity that sour and CO2 brought.These risks centralize mainly in drilling and completion operation(inclusion workover).The paper analyzed the six difficulties of drilling and completion operation in high sour gas field in Chuan-Yu area,and put forward corresponding countermeasures.
