井下作业施工过程中的不压井不放喷作业技术措施

Technical Measures for Non-pressure Well Non-blowing Operation During Underground Construction

井下作业施工是对井筒管柱的作业施工程序,如果采取常规的压井技术措施,会增加压井液的密度,如果处理不当,甚至会引发储层污染事故,给后续油层的生产带来危害。不压井不放喷作业技术措施的施工成本比较低,而且不存在压井液污染环境的情况,但是存在着井喷等安全隐患,需要进行井控设计,建立井喷事故的应急处理措施,提高井下作业施工的安全性。

Downhole operation is a construction procedure for the wellbore string.If conventional killing technology measures are taken,the density of the killing fluid will increase.If it is not handled properly,it will even cause reservoir pollution accidents,and the production zone for subsequent oil layers.Come to harm.The technical measures of non-pressing wells do not discharge,the construction cost is relatively low,and there is no situation that the killing fluid pollutes the environment,but there are safety hazards such as blowout,and it is necessary to carry out well control design and establish emergency treatment measures for blowout accidents.Safety of underground construction.
