摘要
为了鲁克沁油田提液增产,针对其超深稠油油藏的特点和深层稠油采油技术现状进行分析,采用试验电潜泵提液井筒举升工艺,增大了油井生产压差,同时在研究和实践中,初步形成了空心抽油杆井筒掺稀油降粘、防砂电潜泵提液采油工艺配套技术。现场实施表明,单井产量大幅度提高,油田含水上升速度得到控制。该技术为超深稠油油田中高含水期实现经济高效开发奠定了技术基础,具有广阔的推广应用前景。
This paper analyzes the characteristics of ultra deep heavy oil reservoirs and the present status of deep heavy oil recovery technology for Lukeqin Oilfield.Experimental electric submersible pump is applied for well- bore lifting to increase producing pressure drop.In the study and practice process,the supporting techniques have been developed,including viscosity reduction by blending light oil with hollow rod and lifting with sand control ESP.Field implementation shows that single well production has greatly improved and the tendency of water cut increasing is controlled.This technology is helpful to efficient development of ultra deep heavy oil res- ervoirs in medium -high water cut period and will have a promising future.
