improving the oil recovery of old oilfields will affect their continuous and stable development for the whole shengli petroliferous area has entered extra high water cut period.
胜利油区已经整体进入特高含水率开发期,提高老油田采收率直接关系到油田的持续稳定发展。
zhuang block 74 in wuhaozhuang oilfield in shengli petroliferous area is a low- permeability one.
胜利油区五号桩油田桩74块为低渗透油田。
the former one is area with abundant remaining oil and the second one is poor petroliferous area or easy water-out area.
正向微构造一般为剩余油富集区,而负向微构造一般为低含油气区或易水淹区。
the initial results of this criterion applied in the petroliferous area shows it can improve the success ratio of co_2 stimulation in the low permeability oil reservoir effectively.
油区的初步应用效果表明,该标準可以有效地提高低渗透油藏二氧化碳吞吐的成功率。
