摘　　要：王北区块盐间非砂岩油藏以泥质白云岩和钙芒硝白云岩为主,属于孔隙型或裂缝-孔隙型异常高压油藏,在钻井施工过程中容易发生井漏和溢流。采用近平衡及欠平衡压力钻井技术,配合随钻堵漏和复合堵漏,能使井漏与溢流得到有效的控制。Shaly dolomite and glauberite dolomite are the primary part of the inter-salt non-sandstone oil reservoirs of Wangbei Block, which belongs to pore style or fracture style. The pore style oil reservoirs with abnormal high pressure are liable to lost drculation and overflow. The authors hold that near-balance and under balance pressure drilling techniques together with blocking while drilling and compound blocking can effectively control lost circulation and overflow.
