Abstract: Dina 2 Gas Field, which is one of major gas field of Xiqidongshu, with the FMP of more than 106 MPa and the pressure coefficience of more than 2.0, belongs to a low porosity, low particular permeability and abnormal pressure gas reservoir with crack. Dina 2 Gas Field has carried through stress sensitivity experimentation research of reservoir to evaluate rightly elasticplastic deformation with the FMP dropping among developing the gas field. by mean of testing porosity and permeability of drillcore sample under vary effective stress, the paper reserves representative reservoir complete stress strain curve of Dina 2 Gas Field, and depicts quantitatively forever plastic deformation character of rock with the FMP dropping. This job settles basement for confirming flow potential of single well and drawing up development planning of Dian 2 Gas Field, also offers valid method and measure for fundamental research of analogous gas reservoir development.
