成都周边新都马井洛带-凤凰山构造系西南石油分公司重要的勘探开发区块,也是我公司重要的钻探施工地区,随着勘探开发力度的加大,该区域钻井数量还将进一步增加。该区域地层情况复杂,钻井施工中井下复杂情况及钻井事故发生频率高,这些事故及复杂情况的发生延长了勘探开发时间,增加了钻井成本,加大了对油气层的污染,甚至造成有的定向井脱靶,给业主及作业单位都带来了一定的经济损失。为提高钻井技术服务的效益,减少或防止钻井事故及复杂情况的发生,有必要对该区域钻井地质复杂情况及事故进行分析研究,提出预防及处理这些复杂情况的技术措施与方法。
Chengdu around the Xindu Majingluotai - Fenghuangshan Tectonics Department of Southwest Petroleum important exploration and development blocks, but also our company an important drilling construction area, with the exploration and development efforts to increase the number of drilling in the region will further increase . The formation of the region is complex, underground drilling complex wells and drilling accidents occur frequently, the occurrence of these accidents and complications extend the exploration and development time, increased drilling costs, increased pollution of the reservoir, and even cause some Directional well off target, to the owners and operating units have brought some economic losses. In order to improve the benefit of drilling technical services and reduce or prevent the occurrence of drilling accidents and complicated situations, it is necessary to analyze and study the drilling geological complexities and accidents in this area and propose technical measures and methods for preventing and dealing with these complicated situations.
