| 摘 要： | 地应力是影响储层流体压力和驱动油气运移的主要动力之一。首先根据鄂尔多斯盆地苏10区块地质及区域构造应力场的特征,建立了该区块三维有限元模型。通过数值模拟分析,得到了目的层的平均应力、最大水平主应力等地应力等值线分布图,在此基础上进一步计算了油气运移势场。其次,综合分析了构造应力场与流体势场数值模拟结果和气井的生产情况,发现气井的高产井区为地应力场和流体势场的低值区。由此分析认为:在构造应力场作用下,油气易于从地应力场的高值区向低值区运移与富集,从流体势场的高势区向低势区运移与富集。

| Abstract: | Crustal stress is one of the main forces affecting reservoir fluid pressure and driving oil and gas migration.A three-dimensional finite element model is established based on the geology and tectonic stress field in the Su 10 block of the Ordos Basin.The potential field of oil and gas migration is computed based on the crustal stress contour of the mean stress and the maximum horizontal principal stress of the target layer derived through numerical simulation.Comprehensive analysis of the results of numeric... |
