摘要
四川在2002年形成全过程欠平衡钻井完井技术后,近几年欠平衡钻井完井技术又取得了新进展。针对欠平衡钻井完井技术存在的问题和不足,对欠平衡钻井完井工艺技术和欠平衡钻井装备进行了进一步的研究完善。运用欠平衡钻井完井配套技术和研制的欠平衡钻井装备,从2003～2005年,在川渝地区共开展了141井次的欠平衡钻井完井推广应用,取得了良好的技术经济效益。
After forming a completely UBD drilling and completion technology in 2002,some new developments about UBD drilling and completion technology had been achieved in the past three years in the Sichuan Oil & Gas Field. According to the existent problems and deficiency about underbalanced drilling and completion technology, lots of research works were carried out to improve the technology and equipments. These improved technologies and equipments were applied in 141 wells in Sichuan and Chongqing region, good economic benefits have been achieved in recent three years.
