盘1-17断块含油面积0.25km~2,地质储量129.4万吨,采出程度22.4%,区块水井5口,油井8口。地层平均渗透率204.2×10~(-3)um~2,地层水矿化度40000mg/L,属中低孔渗、高盐油藏,动态显示区块存在明显水窜,综合含水高位运行。本文以该区块油井为中心,以井组为单位,通过综合分析、比对油水井测井曲线、作业井史、生产动态反应情况,结合射孔和吸水剖面数据,分别得出8口油井与对应水井的注入水窜流方向及出水小层,并有针对性的给出了该区块整体堵调技术方案。
Block 1-17 fault block oil area of 0.25km ~ 2, geological reserves of 1,294,000 tons, mining level of 22.4%, block 5 wells, 8 wells. The average permeability of the formation is 204.2 × 10 ~ (-3) um ~ 2, and the formation water salinity is 40,000 mg / L. It belongs to medium and low porosity and permeability reservoirs and high salt reservoirs. In this paper, the oil wells in the block as the center, the well group as a unit, through comprehensive analysis, compared well logging curves, operating well history, production dynamic response, combined with perforation and water absorption profile data, respectively, 8 wells And the corresponding wells injected into the direction of water channeling and water out of the small layer, and targeted the block block the overall program of technical solutions.
