摘要
Abstract
The gas reservoir in Sulige gasfield, Ordos Basin, is a typical low-permeability tight sandstone gas reservoir. The major gas reservoir He 8 is characterized by bad physical property, strong anisotropy and complicate gas-water distribution. With the tested and explored data, the water is divided into three types as following, adsorbed water and capillary water and free water. The adsorbed water mainly exists in the surface of rock particles ; the capillary water exists in the capillary tubes of strong anisotropy reservoirs; the free water exists in the reservoirs with good pore structure and physical property. According to the hydrocarbon-generating intensity and heterogeneity, the gas-water distribution control factors were analyzed; the hydrocarbon-generating intensity dominates the macro distribution of gas and water; the reservoir heterogeneity controls the partial distribution; the micropore structure controls the water occurrence situation.关键词
