鄂尔多斯盆地苏14井区盒8段储层宏观非均质性研究
|
摘要
苏里格气田位于鄂尔多斯盆地北部,研究层段盒8段属于典型的岩性圈闭气藏,具有低孔、低渗、低丰度的特点。以苏里格气田中区苏14井区为研究目标,在明确地层系统划分和区域地质特征的前提下,运用测井、试气等实际生产资料,同时结合研究区沉积相研究成果,分别对苏里格气田苏14井区盒8段储层层内非均质性、层间非均质性和平面非均质性进行研究。结果表明,苏14井区盒8段层内和层间非均质性都表现出极强程度,平面非均质性要相对较弱。其中盒8上段砂体沿主河道方向砂体连续性较好,而垂直主河道方向上砂体叠置频繁、连续性差,导致层间非均质性极强。
Sulige gas field,located in the northern part of the Ordos Basin,and study interval is a typical lithologic gas reservoir characterized by low porosity,low permeability and low abundance. In this paper,the in-layer,horizontal and interlayer reservoir heterogeneities in the member 8 of Lower Shihezi Formation are analyzed by using the logging and gas testing data and combining with stratigraphy premise systems,regional geological features and sedimentary facise research in Su 14 wellblock. The results suggest that,both their in-layer and interlayer heterogeneities are strong in the member 8 in Su 14 wellblock,and are stronger relatively than the horizontal. Sand-bodies are highly developed in the upper part of the eighth member of Shihezi Formation. Their continuity is good along the channel but poor perpendicular to the channel,resulting in the strongest interlayer heterogeneity.
