苏里格气田位于鄂尔多斯盆地伊陕斜坡西北侧,构造形态为宽缓的西倾单斜,主要目的层为二叠系石盒子组和山西组地层,储层非均质性强,具有低压、低渗、低产、低丰度的特点。该区域气田主要受砂岩横向展布和储集物性变化所控制,属于致密砂岩气藏。一、储层特征(一)岩性及沉积特征储层岩性复杂,储层纵向及横向上由多种岩
The Sulige gas field is located on the northwestern side of the Yi-Shan slope in the Ordos Basin. Its structural form is gentle west-dip monoclinic. The main target strata are the Permian Shixianzi Formation and Shanxi Formation. The reservoir is characterized by high heterogeneity and low pressure, Low permeability, low yield, low abundance characteristics. The gas field in this area is mainly controlled by the lateral distribution of sandstone and the change of reservoir physical properties, which belongs to tight sandstone gas reservoirs. First, the reservoir characteristics (A) lithology and sedimentary characteristics Reservoir lithology complex, vertical and horizontal reservoir by a variety of rocks
