Research On Test Design And Analysis Methods Of Major Reservoirs In The Western South China Sea

The reservoirs in the western South China Sea are complex and the pre.test reservoirs and the fluid parameters are difficult to predict.The production rules of different reservoirs,different well types and different completion methods are not systematically studied,and the test performance is affected.Logging interpretation,the relationship between the core analysis parameters is not clear,affecting the reliability of well test design,well testing work after the assessment work carried out very little.In this paper,according to the complex conditions of the western part of the South China Sea,the reservoirs and fluid properties,production rules and test experience of various types of oil and gas reservoirs and oil and gas wells are improved,and the BP neural network method,multiple regression analysis method and cluster analysis method are used to establish reservoir parameters.The model of porosity and well permeability is established,and the effective permeability model of well logging is predicted.The fluid type and gas composition of the main reservoir in the western South China Sea are analyzed,and the physical properties of the fluid.The relationship between the physical properties and the physical properties of the reservoirs and the physical properties of the reservoirs were established.The relationship between the production capacity and the reservoir physical properties and the physical properties of the reservoirs was established.The distribution rules of the reservoirs in the western South China Sea were analyzed.Low permeability reservoir test design and pressure analysis method;put forward before and after drill test design,test dynamic real.time online and optimize the adjustment method.
