针对小井眼井目前在油层改造、封堵改层、分层采油等工艺措施遇到的技术颈瓶,开展小井眼井工艺措施配套技术研究,主要包括小井眼井封堵技术研究与推广应用,小井眼井卡封采油技术研究应用,小井眼井酸化、压裂技术研究与应用等三方面内容;近两年共实施小井眼采油工艺措施26井次,工艺成功率96.1%,有效率达88.5%。形成一套完整、系统化的小井眼井采油配套工艺,对提高小井眼井开发效益具有十分重要的意义。
Aiming at the technical bottlenecks encountered by Slim wells in the process of oil layer alteration, plugging and stratification, stratified oil recovery and other technological measures, the research on the supporting technology of slim hole and well technical measures is carried out, including the research and popularization and application of slim hole occlusion technique, Research and application of sour hole in well, research and application of fracturing technology and so on. In the past two years, a total of 26 wells with well drilling technology have been implemented, with a success rate of 96.1% and an effective rate of 88.5 %. It is of great significance to form a set of complete and systematical supporting technologies for the well production of slim wells.
