摘要
鄂尔多斯盆地XY区块自2009年投入开发以来,暴露出注水有效驱替系统难建立、压力保持水平低、单井产能低、方向性见水、提单产难度大等问题矛盾凸显。针对该区"注水不见效,见效即见水"的特征,近几年通过注水井深部调驱、注水井分层注水、周期注水、沿裂缝加强注水、开展油井化学堵水试验,取得一定的认识,通过对比分析认为堵水调剖在该区适应性较好,下步建议扩大试验,提高区块整体单井产能,降低递减,确保该油藏持续稳产。
Since the development of XY block in Ordos basin in 2009, the contradiction between the effective displacement system of waterflooding, the low level of pressure maintaining, the low productivity of single well, the water yield in directional direction and the difficulty of raising unit yield have been exposed. In the area of water is not effective, effective to see the characteristics of water, in recent years through deep water injection flooding, water injection well stratified water cycle water injection, water injection, carried out along the cracks strengthen chemical water plugging test, has certain understanding.Through the comparative analysis that water shutoff is better in the area the next step to expand the adaptability test, improve productivity, reduce the overall decline of single well block, to ensure the sustainable development of reservoir.
