Research on the Influence of Reservoir Physical Property Time Change on Reservoir Water Drive Development

Abstract

With the continuous development of China’s social economy, the total demand for energy in China’s industrial production is constantly increasing, among which petroleum energy is an important energy type needed in industrial production. China’s petroleum energy mainly depends on imports, which is very unfavorable to China’s economic development and energy security strategy. Therefore, it is necessary to improve China’s oil exploitation efficiency, increase oil production and alleviate China’s energy shortage. In this paper, the influence of time variation of reservoir physical properties on reservoir water flooding development is deeply studied and analyzed, and some reasonable suggestions and measures are put forward to further promote the development of China’s petroleum development engineering industry. In the oil field developed by water flooding, the long-term scouring force of water will lead to a series of complex physical and chemical changes in the microscopic space of oil reservoir, which will lead to certain changes in the physical parameters of oil reservoir. This phenomenon is called time-varying physical properties. Time-varying physical properties are the main factors affecting reservoir exploration and development, so it is necessary for staff to grasp the relevant technical key points, so as to make clear the changes and the changed reservoir physical parameters. According to the changes, the subsequent work will be adjusted accordingly. Time-varying reservoir will affect the movement law of oil and water in the reservoir, thus affecting the actual development effect of the reservoir, and also affecting the distribution of remaining reservoirs after reservoir development.
