北部湾盆地各油田钻井作业主要难点分析

Analysis of main difficulties in drilling operations in various oil fields in Beibuwan Basin

北部湾盆地是南海西部油田的原油主产区,由于区域地质构造复杂,断层裂缝发育,非均质性强,地层水敏性强,钻井实施过程中难点众多,极易出现各种问题,严重制约南海西部油田的总体开发难度。笔者结合多年现场作业经验,对北部湾盆地各油田开发不同区块、不同储层的井钻井作业过程中的难点进行了归纳。

The Beibuwan basin is the main producing area of crude oil in the western South China Sea oil field.Because of the complex geological structure of the region,there are many difficulties in the implementation of drilling.Based on many years'experience of field operation,the difficulties in developing well drilling operations in different blocks and reservoirs in the Beibuwan Basin are summarized.
