摘要
鄂尔多斯盆地致密油气资源丰富,但目前子洲气田已逐步进入稳产后期,低产低效井比例逐年增加,为提高单井产量,弥补递减产能,选取部分主力层砂体发育,储层物性好,与邻井储层物性相似,但生产动态较邻井差的老井开展重复压裂改造。
Tight oil and gas resources are rich in the Ordos basin, but the Zizhou gasfield has gradually entered the later period of stable, stripped deficent well ratio increased year by year.In order to improve the yield of a single well, make up for declining production capacity, select some of the main layer of sand body development,reservoir adjacent wells, reservoir physical property is similar to, but dynamic production compared with the adjacent wells of poor old wells to carry out repeated fracturing.
