低渗透油田开发后期综合治理技术研究

Research of Comprehensive Improvement Technology in the Late-Stage Development of Low Permeability Reservoirs

随着开发时间的延长，部分井开始出现低效或无效益生产，投产时间越长这种现象越明显，有的油藏低效井已达30％左右。、低产低效井已成为制约油田开发整体效益提高的重要因素。本研究依据地质录井、测井和采油生产数据等成果资料，剖析了研究区采油井低产低效的原因．运用了改层、压裂、酸化、补孔、调参、堵水等综合工艺措施．达到了提高单井产量的目的。

With the extension of development time, a part of the well began to generate low or no benefit production, the production time is longer, the phenomenon is more obvious, and the low efficiency wells of some reservoirs bare reached about 30%. Low production and inefficient wells have become important factors for limiting the improvement of oilfield development overall effectiveness. The study analyzes the reason of low production and low yield of the studied zone. aceording to resuh data such as geological logging, logging and oil production data information and the like, and uses comprehensive technique measures such as layer changing, fracturing, acidizing, filling holes, scheduling, water control and the like, anti the purpose of improving the unit well production can be achieved.
