| Abstract: | Exploration and research show that Xujiahe Formation has a favorable exploration potential in Northeast Sichuan Basin,particularly Yuanba Region has become the key block of middle-shallow gas exploration.Based on the integrated study of lithology-structure gas reservoir of the second member and the fourth member of Xujiahe Formation in Malubei,the lithologic gas reservoir of the second member of Xujiahe Formation and the structure-lithology gas reservoir of the fourth member of Xujiahe Formation in Yuanba,the accumulation conditions and main controlling factors of gas reservoir are analyzed in Northeast Sichuan Basin.It is believed that the forming conditions of large-middle gas reservoir have been shown in Upper Triassic Xujiahe Formation of Northeast Sichuan Basin.For the gas accumulation of Upper Triassic,main controlling factors are the abundant source rock,favorable conductivity condition,timely palaeohigh,developed trap,thick reservoir with large-area distribution,excellent reservation and seal conditions. |
