Abstract

Water soluble gas is one kind of natural gas which are mainly composed of methane. The concentration of water soluble gas is dominantly controlled by temperature、pressure、water salinity as well as the water capability of the reservoir. The water-soluble gas resource underground become rich as water storage capacityrises at higher temperature and pressure of the water medium. Both the quantity of natural gas resources underground and the water production of the drilling well per day as well as the quantity of gas released on the surface should be concerned. The more highly decreasing of the water soluble gas producing pressure, the more amount of gas being released. Commonly, gas saturation of water underground varies from 1 m³ to 10 m³, but in east sedimentary basin of china such as Daqing area the figure is highly up to 4 500×10⁸m³ that equal to a over 4.5×10⁸ t reserve field. The exploration of watersoluble gas in our country has good respects.

Key words： Songliao basin; Water-soluble gas; Oil and gas resource; Oil and gas concentration.
