钻井井控设计中三个不容忽视的问题及建议

Three Problems and Suggestions in the Design of Drilling Well Control

为进一步优化中海石油(中国)有限公司的井控设计,使其具有更丰富的现场指导意义,结合现场巡检工作以及对井控设计内容的分析,指出井控设计中对关井能力方面缺少针对性、具体性的设计指导,从剪切闸板实际剪切能力评估、防喷单根/立柱的设计与应用以及应急操作指导三个方面给出建议,便于迭代井控设计内容,提升井控设计质量。

In order to further optimize the well control design of CNOOC(China) Co., Ltd. and make it more meaningful for on-site guidance, combined with the on-site audit work and the analysis of the well control design content, it was pointed out that the well control design lacked targeted and specific design guidance for the shut-in capacity. In this paper, from three aspects of the evaluation of the actual shear capacity of the shear ram, the design and implementation of the anti-blowout single joint/stand and emergency operation guidance, some suggestions were given from these, so as to iterate well control design content and improve well control design quality.
