Research Of Non-linearity Filtration Theory In Non-isotropic Reservior

This paper is based on practical problems faced in procedure of development of reservoir of low permeable sublayer of anisotropic medium, contributing to the efforts of predecessors who expended, we have run a analysis about fundamental feature of microcosmic flow of reservoir of low permeable sublayer of anisotropic medium, through the research of theorem, we found the law of movement among chief parameters of flow of low permeable sublayer of anisotropic medium, this paper reveal that mechanism of flow of low permeable sublayer of anisotropic medium.What we have done is as followed:Through running a research to make a difference among the reservoir of anisotropic medium and isotropic medium and anisotropy, to find tensor property of anisotropic permeability and the property of reservoir of non-linear fluid flow of anisotropic permeability ,and integrating geologic characteristic of reservoir of low permeable sublayer, through runing a meticulous analysis about procedure of reservoir of low permeable sublayer of non-linear fluid flow, we elaborate the mechanism of microcosmic flow of reservoir of low permeable sublayer of anisotropic medium, establish concrete algorithm of procedure of development of reservoir of low permeable sublayer of anisotropic medium, consider shot pressure gradient lie in procedure of reservoir of low permeable sublayer of non-linear fluid flow.We have established the model of single phase filtering flow, two-phase of profit filtering flow, and two-phase of oil gas filtering flow, and find the answer of analysis or approximation. according to the condition of actual production, we find the equation of flow potential in well and pressure distribution of formation in different condition.We have run a analysis about sensitivity of parameters of reservoir of non-linear fluid flow of anisotropic medium. through integrating theory equation and produce practice ,we find the changement relationship of parameters of non-linear fluid flow in different condition, and the main parameters of non-linear fluid affect flow potential in well and pressure distribution of formation, and plot a curve of how parameters of non-linear fluid flow can affect them in different condition.This paper will promote the fundamental theory of reservoir of non-linear fluid flow of anisotropic medium, lay meaning of guide on exploit of reservoir of low permeable sublayer.
