| 摘 要： | 安塞油田坪北区为低渗透裂缝性油藏,多项研究表明微裂缝在安塞油田坪北区C4+52、C6油藏中是客观存在的,并且具有一定的规律性。生产动态表明油层存在双重孔隙介质,利用油藏裂缝特征,采用沿裂缝方向布井、在开发过程中加密调整注水开发井网、开展不稳定注水、沿裂缝方向强化注水、暂堵压裂均取得较好的注水开发效果。

| Abstract: | The Pingbei Area of Ansai Oilfield is a low permeability reservoir with crevice.A number of researches indicated that the micro-crevices exist objectively in the C4+5_2 and C6 reservoirs with some regularity.The production activities show that some double porosity systems exist in oil-layer.By well spacing along the crevice location according to the crevice characteristics,infilling &adjusting some water-injection development patterns,injecting water unstably,strengthening water-injection along the crevice location and temporary shielding fracturing in the course of development,a better effect has been achieved. |

| Keywords: | Pingbei Region of Ansai Oilfields crevices ultra-low permeable reservoirs infilling and adjustment inject water unstably water-injection strengthening temporary shielding fracturing |
