Abstract:
Based on the mechanism of steady state continuous hydrocarbon expulsion of mature hydrocarbon source rock, the control of connected sandbody on oil-gas migration in terrestrial facies mature hydrocarbon source rock was analyzed, and the effects of contact area between hydrocarbon source rock and sandbody in it, content of sandstone in the bed series of hydrocarbon source rock with interbedded sandstone and mudstone, physical property, distribution and continuity of sandbody to expulsion efficiency of hydrocarbon were discussed. The results showed that the contact type between connected sandbody and hydrocarbon source rock was divided into vertical sedimentary facies transition contact, lateral sedimentary facies transition contact and staggered compound contact, and the vertical and lateral sedimentary facies transition contacts were the main types; the type for the combination of connected sandbody and hydrocarbon source rock was mainly steady state continuous hydrocarbon expulsion driven by abnormal pressure; the greater contact area, content of sandstone, physical property, distribution and continuity of sandbody, the better expulsion efficiency of hydrocarbon of mature hydrocarbon source rock, and then the main hydrocarbon expulsion direction and resources were controlled. The effect of connected sandbody in hydrocarbon source rock on secondary oil-gas migration depended on the continuity of distribution and connectivity of physical property between the connected sandbodies inside and outside hydrocarbon source rock. If sandbody in hydrocarbon source rock was isolated and oil and gas could not migrated outside the rock, reservoir inside hydrocarbon source rock was formed; if the continuity of distribution and connectivity of physical property between the sandbodies inside and outside hydrocarbon source rock were great, the distance of oil-gas migration was large, and the reservoir formed in more favorable closed loop area.
