Sensitivity Quantification Study on the Main Influencing Factors of Water-Flooding Development in Medium Permeability Reservoir

There are many factors that affect the development effect In the development process of medium porosity and permeability reservoirs. Clarifying the degree of influence of different influencing factors is conducive to further improving the development effect. This paper establishes the model and studies the main factors influencing the development of the reservoir based on the reservoir parameters of Zaoyuan oilfield and Wangguantun oilfield. Quantify the relationship between single factor changes and development effectiveness using reservoir numerical simulation methods. Based on this, the sensitivity of factors that affect development effectiveness is divided into three categories from high to low by establishing a sensitivity comparison method for different single factors. The influencing factors of high, medium, and low sensitivity levels. The research results provide a method for improving the development effect by optimizing and regulating the main influencing factors during the development process.
