哈拉哈塘油田碳酸盐岩油藏开发技术

Development for carbonate reservoir in Halahatang Oilfield

哈拉哈塘油田储层具有极强的非均质性,其产能分布、含水率变化及地层能量等具有明显的多样性,钻遇洞穴型储集体开发效果明显好于裂缝-孔洞型储集体,洞穴型储层以无水生产井为主,裂缝-孔洞型以波动型和暴型水淹为主。开发方式必须根据各单井控制区块实际情况进行选择,按"一井一策"进行差异化管理。

The reservoirs in Halahatang Oilfield have strong heterogeneity,whose capacity distribution,change of watercontent and energy of strata are diversified.The development effect in drilling cave type reservoir is better than that of fractured vuggyreservoir,anhydrous production wells are widely used in cave type reservoir,fluctuation and violence type flooding are for fracturedvuggy reservoirs.Development methods must be chosen according to the actual situation of blocks where single wells locate,anddifferentiated management should be carried out according to“one method for one well”.
