Study and Application on Well Test Analysis of Low Permeability Reservoir in Daqing Oil Field
There are some reservoirs with character of low porosity, low permeability, low abundance of OOIP and low productivity in Daqing Chanyuan and outer regions, it is important to know the flow rule and characteristic of them. This paper sets up low permeability homogeneous and composite reservoir mathematic models by introducing start-up pressure gradient factor in flow equation, gets type curves of well-test interpretation, builds a set of method and software for Daqing low permeability reservoirs. By using the method and soft, some major factors including well bore storage, skin, permeability, mobility, start-up pressure and formation pressure can be gotten, which can provide some useful information on development and regulation of low permeability reservoirs.
