The Physical Simulation Experiment Of Steam Flooding In Heavy Oil Reservoir Of A Block

This article take the A block as the research aim sub-area, the block belongs to shallow heavy oil reservoir, reservoir pressure low, conventional water flooding development difficulty, need through indoor physical simulation experiments and other research methods, the research for the block of heavy oil thermal recovery feasibility, injection production parameters and related technologies. Due to the high viscosity of crude oil, making the conventional reservoir development when injected water easily onrush, the development process is characteristic of early water rose quickly, a large number of crude oil is often in high water cut stage in the recovery, it is difficult to achieve the use of cost-effective, belongs to the reserves.It is considered that the steam injection development in this area has a certain feasibility, and it is necessary to further deepen the research of the reservoir and the matching process to obtain better development effect and economic benefit. Combined with the main characteristics of reservoir development and technical selection, and draw on the near field test of the understanding, the steam drive in improving the effectiveness of the development of the reservoir has a great technical potential. Therefore, it is necessary to carry out the feasibility study of steam flooding in this area.Around this topic research goal, the combination of indoor experiments and theoretical research methods, research, analysis of the domestic and foreign about a variety of heavy oil development mechanism of results and experimental method and carries on the summary, using physical model is used to simulate the heavy oil reservoir with low permeability and different temperatures in different permeability with different ways of flooding for experiment and research of different ways of driving oil efficiency and production performance. By different temperature and different permeability of heavy oil flooding for the obtained under different conditions of relative permeability curve of relative permeability characteristic curve and study of heavy oil seepage law, draw a conclusion of the experiment, explore effective economic trouble reserves the use of technology.
