After the oil field enters the middle and high water content period,it becomes a difficult problem to exploit the remaining oil,and the study of microstructures provides a feasible method. The research shows that the oil wells of positive microstructures were in good production,and the water came later. Meanwhile,water content rose more slowly,and most of the remaining oil enriched. The oil wells of negative microstructures were in bad production,and the water came early. Meanwhile, water content rose more quickly,and less of the remaining oil enriched. The oil wells of sloping formation microstructure did between the two above.%油田进入中高含水期之后,如何动用剩余油成为难题,而微构造研究则提供了一种可行的方法.研究表明,正向微构造部位的油井生产情况最好,见水晚,含水上升慢,同时也富集最多的剩余油;负向微构造部位的油井生产情况最差,见水早,含水上升快,同时剩余油也最少;而斜面微构造部位的油井生产情况介于两者之间.
