摘要:
L油田是渤海最大的陆相多层砂岩油藏,含油井段长,单井钻遇油厚度大,采用一套层系多层合采合注。历经十多年的注水开发,油田进入中高含水期,开发矛盾突出,特别是纵向上主力砂体存在严重超压、欠压问题,对油田各类增产增注措施和调整井的实施有很大影响。通过对油田评价井岩心粒度的分选性统计分析,认为储层分选性差和不合理生产压差制度是造成油田主力砂体超压、欠压的主要原因,为多层砂岩油藏改善开发效果提供依据。
Abstract:
L Oilfield is the largest sandstone reservoir with continental multi-layers in Bohai Sea, which has longer oil bearing interval, larger thickness of drilled oil layers of single well, and mutilayer production and injection using a set of layer series. After more than 10 years waterflooding, the oilfield has entered into the middle and high water-cut stage. And the development contradiction is becoming more and more prominent, especially serious overpressure and underpressure problems of main sandbodies in vertical direction, having great influence on various kinds of well stimulation and adjustment well implementation. Through statistically analyzing the sorting of granularity of cores in evaluation wells, it is believed that main reasons of overpressure and underpressure in major reservoir are poor sorting of reservoir and unreasonable production pressure differential scheme. The results can provide the basis for improving the development effect of multi-layer sandstone reservoirs.
