Dynamics Of Horizontal Wells Inflow Forecasting Methods

At present,technology widely used in the world of horizontal wells is a kind of can be applied to oil and gas field development and abandon the important mining technology can effectively improve the efficiency of.It can effectively improve the exploitation of oil and gas function.In the course of study on the technology of horizontal well in,for further study into the dynamic,and the horizontal well flow and productivity analysis can better play the implementation of technical method of well level,while the horizontal.well technology is currently the external oil gas field development is an important means to improve the process of oil and gas reserves recovery.So the research and productivity analysis of inflow of horizontal well can give full play to the potential of horizontal well exploitation,so as to improve the development effect of the oil storage,and ultimately improve the economic benefits of mining.According to the research into the dynamic prediction method for horizontal well is an important content of horizontal wells and multilateral wells of oil and gas reservoir production of energy and determination of enhanced oil recovery,in our analysis of inflow to the production process,can determine the reasonable working system,and this will be for the optimization design of production project to provide a theoretical basis for the scientific and reasonable.In this paper,through the research on the method of dynamic prediction of inflow of horizontal wells,improve the theoretical support for the horizontal well productivity of Chinese oil and gas storage and recovery efficiency,and through the analysis of inflow performance of horizontal well productivity effect,can also for establishing the system of oil and gas field work provides a method to determine the better,in addition,also can lay a theoretical basis for the optimization design of oil and gas exploitation technology scheme,and its actual application plays a certain reference and practical value.This paper starts from the underground seepage theory of oil and gas fields to proceed,a two-dimensional steady flow analysis model,based on the similarity principle of hydropower,analytical model into the dynamic analysis.Taking into account the correction for the anisotropic analytical model,thus giving the famous or op/C of Lyapunov and Joshi formula,is mainly to the inflow conditions in various dynamic horizontal wells are analyzed.This paper is to study the horizontal well inflow performance relationship,in the research process is based on the multiphase flow based on the characteristics of comprehensive,including the analysis of oil gas two phase flow,the oil-water two-phase flow and oil gas water three-phase flow into the dynamic aspects,in addition,a variety of the main application level well IPR equation.
