| Abstract: | According to the analyses of drilling, well logging and pressure detection data, it is held that there is an overpressured compartment in Kuche Depression, Paleogene gypsum and upper—middle Jurassic shale layer constitute the top cover and the bottom cover of the compartment separately, the thrust faults and the strike-shift faults around the compartment constitute its side covers, and the glutinite layer in the bottom of Paleocene and the sandstone layer of Cretaceous constitute the main strata series of the compartment. Kela2 compartment is the basic unit for gas migration and accumulation of Kela 2 gas field, and the result of calculation shows that the compartment has a very high efficiency of gas accumulation. |
