Problems Analysis and Proposed Amendments for Current Drilling Well Control Standards

In order to improve the scientificity and practicability of well control standards and give full play to the guiding role of well control standards in drilling operation,this paper analyzed 8 current drilling well control standards(national standards and industry standards).Based on the current status of well control technology,and the requirements on well control techniques and devices in drilling,giving full consideration of well control function of the devices and well control equipment with minimum requirements and the necessary safety margin,the paper pointed out 17 major problems in the current 6 effective standards,in terms of BOP combinations,well control manifold and shut in procedures.Through in-depth analysis of the problems,possible solutions were proposed and explained.Proposed changes were based on the actual oilfield well control situation,which provided basis for further improvement and revision of relevant well control standards.
