Abstract:

 The water-soluble gas degasification and accumulation is the key issue of many oil geological workers, especially the crucial period of the water-soluble gas degasification. If have good condition of reservoir, trap and preservation in that period, the gas can accumulate. By means of the analyzing data of inclusion, formation water salinity, temperature and pressure, combining with basin simulation and regression equation of gas solubility, this paper calculated the gas solubility of Shaximiao Formation at the key periods in Chengdu Depression, and researched the alternation characteristics of gas solubility. The results show that the time from the primary time of hydrocarbon expulsion of the source rocks in the fifth member of Xujiahe Formation to the hydrocarbon accumulation period of Shaximiao Formation, the gas solubility is lowest, which is the key period for the water-soluble gas degasification.

Key words:  water-soluble gas degasification, crucial period, Shaximiao Formation, Chengdu Depression
