| 摘 要： | 王官屯油田孔一段储层为近源快速堆积的扇三角洲砂体,岩性细、层薄,成岩作用弱,储层结构疏松,油井生产时普遍出砂。从沉积微相、储层非均质性、岩石微观结构、开发措施等多方面,论述了王官屯油田官195断块孔一段枣Ⅴ上油组油井出砂问题,基本搞清了地层出砂机理、原因和规律;通过定量计算,预测了出砂层位和出砂部位,提出了综合治理的技术对策,即对出砂严重的油水井采取封堵出砂严重层位,新井避射薄油层和厚油层顶部,注水井控制好注水压力和合理配注。

| Abstract: | The reservoir of Wangguantun oilfield is a rapidly deposited fan-delta sandbody near source area. Because of fine lithology, thin layer, poor diageneses and loose reservoir structure, sand production is quite common in production wells. The problem of sand production is discussed from the aspects of sedimentary microfacies, reservoir heterogeneity, rock microstructure and development measure, and the mechanism, reason and law of sand production are found. Through quantitative analysis, the sand production layer and area are predicted, and the technique methods for controlling sand production are proposed, that is, sealing off sand layers in serious sand production wells, avoiding the thin oil layers and the top of thick oil layers during gun perforation in new wells, and controlling flood pressure and injection allocation. |
