喇嘛甸油田进入特高含水期后,低产低效井井数呈逐年上升的趋势,截止2007年底水驱共有产量小于2吨的低产低效井395口,这些井制约着油田开发后期的经济效益以及全油田产量的顺利完成。本文在油层精细描述和储层内部结构界面研究成果的基础上,深入分析了油层剩余油的分布规律特征、动用程度,加强措施井选井选层方法研究,并通过补孔、压裂等增产措施挖潜油层剩余油,提高储层动用程度,达到了综合治理低产能恢复上产的目的。
After the Lamadian oilfield entered the special high water cut period, the number of low productive and inefficient wells showed an upward trend year by year. By the end of 2007, there were 395 low productive and inefficient wells with output less than 2 tons, which restricted the economic benefits in the late stage of oilfield development As well as the successful completion of the entire oilfield production. Based on the detailed description of the reservoir and the research results of the interfacial structure of the reservoirs, this paper deeply analyzes the characteristics of the remaining oil distribution, the degree of utilization and the method of well selection and well selection. Measures to tap the remaining oil in the submarine reservoir and improve the utilization of the reservoir have reached the purpose of comprehensively controlling the low-yield recovery and yielding.
