Research on the influencing factors of fine tapping development indicators

A block carried out on-site experiments to reduce water cut and enhance efficiency, mainly focusing on improving the utilization of thin differential reservoir layer and low efficiency circulation management, exploring further methods to improve oil recovery and achieving phased progress. Along the continuous reservoir development, new features have appeared in water flooding development, and the changes in development index and technical boundaries have also undergone significant changes. Therefore, it is requisite to perform a detailed analysis on the influencing factors of development indicators. This research quantified the different influencing factors on water content and decline patterns in different phases of fine potential excavation. The degree of influence of each factor in different phases was determined through grey correlation method and measure impact value splitting method, and the main influencing factors in each stage were given. Summarize the experience and model of fine excavation and submersible flooding development, and lay solid foundation for sustainable and high-efficiency development in the next step.
