摘要
目前,国内的老油田普遍采用水驱技术以提高油井的采收率,加密调整井在钻井施工中受注水压力影响而频繁发生井漏、溢流等复杂现象,甚至因此造成工程报废。本文根据bDT2001井在钻井过程中发生的各种复杂现象,剖析其发生原因及结果,并提出了合理、有效的技术措施。
Currently,water flooding technology is widely used to improve well recovery in domestic maturing oilfields. Complex phenomena such as well leakage,overflow influenced by the water injection pressure constantly happen during the drilling of infilling adjustment wells,which even causes the engineering abandonment. According to various complicated phenomena happened in the drilling process of bDT2001 well,this paper analyzes the causes and results,and discusses their reasonable and effective technical measures.
