摘要
随着压裂工艺技术多样化,压裂规模也有逐步扩大趋势,但同时易造成套管的大量损坏失效。套管损坏不仅会带来巨大的经济损失,也使油气勘探开发井不能正常生产,影响油田勘探开发方案的继续实施和整体经济效益的提高。对油层压裂改造套管损坏机理开展研究,在此基础上制定套管损坏预防措施和防治办法,对油气田勘探开发的生产实践具有重要意义。
With the diversification of fracturing technology,the fracturing scale has a tendency to expand gradually,while,it is also easy to cause the casing failure and damage greatly. It not only brings huge economic losses of casing damage,also makes the wells of oil and gas exploration and development can not be normal production,to influence the continuous implement of oilfield exploration and development project and improvement of the overall economic benefit. The research on mechanism of casing damage from fracturing to oil layer has been conducted,and on the basis of it,prevention and control measures for casing damage have been developed,which has important significance for the production practice of oil and gas exploration and development.
