STUDY ON EFFECTIVE HYDROCARBON SOURCE ROCKS AND RELATIONSHIP BETWEEN THEM AND NATURAL GAS RESERVOIRS
有效烃源岩及其与天然气藏关系探讨

In the study of natural gas genesis and exploration, it is still our major task to determine effective hydrocarbon source rocks and accumulation assemblage. In terms of primitive basin, the low limit of organic carbon in effective hydrocarbon source rocks (whether carbonate rock limit or shale) is 0.5%. While in polycyclic superimposed sarsen basin, this value is not suitable to secondary hydrocarbon generation. The limits of secondary hydrocarbon generation in different maturation stages are as follows: wh...
