志丹片钻井溢流控制措施的探讨

Discussion on Drilling Overflow Control Measures in Zhidan Area

对2016年中国石油长庆油田分公司工程监督处工程总监工作站(志丹)所辖6个产建项目组上半年溢流井发生的区域、溢流时钻达层位、注水井停注、溢流介质、钻进及压井泥浆密度等方面进行了统计分析,发现了存在的问题并及时采取了相关措施。通过下半年的实践,使钻井溢流数量得到有效控制。

Through the statistical analysis of the areas and the horizons where drilling overflow occurred, whether or not to inject water, the overflow medium and the mud density when drilling overflow was occurring in the first half of 2016, the problems were found and the corresponding measures were taken timely, which effectively controls the number of drilling overflow accidents in the second half of 2016. There are 6 production and construction groups in statistical region, which are administered by Engineering Director Workstation （Zhidan） of Engineening Supervision Department, Changqing Oilfield company, CNPC.
