通过对研究区气藏的温压、流体特征、以及气藏地球化学特征的分析,明确了气藏的基本性质,依据构造分布,储层非均质性以及气源岩的影响进一步明确了气藏的分布特征,综合研究认为本区的气藏为干气,含有少量的油型裂解气,气源判断属于混源气。气藏的分布主要受垂直渗流带的影响,没有明显的边底水特征,非均质性是决定气水分布的主要因素。 Based on the analysis of the temperature and pressure, fluid characteristics and geochemical characteristics of gas reservoirs in the study area, the basic properties of gas reservoirs were clarified and the gas was further clarified according to the tectonic distribution, reservoir heterogeneity and the influence of gas source rocks According to the comprehensive study, the gas reservoirs in this area are dry gas with a small amount of oil-type pyrolysis gas, and the gas source is classified as mixed gas. The distribution of gas reservoirs is mainly affected by the vertical seepage zone, and there is no obvious characteristics of edge-bottom water. The heterogeneity is the main factor that determines gas-water distribution.
