REMIND OIL DISTRIBUTION AND IMPROVEMENT PRODUCTION POTENTIAL STUDY ON HIGH WATER CUT COMPLEX FAULT BLOCK OIL RESERVOIR

The oil remaining distribution is complicated in high water content ratio continental facies complex fault block oil reservoir, so the reservoir simulation is difficult. In this paper, the dynamical static data was obtained based on the reservoir detailed description of Ma 11, the result combined with thick gridding simulation to study the oil reaming distribution. Aimed at the reservoir oil remaining specialty and economic technology, put into effect the plan of the improvement the oil remaining production potential which consisted of the adjustment well, profile modification, water plugging, well major repair etc. Now, the reservoir water cut smart decline, oil recovery rate is climb and the recovery ratio improve 0.7 percent. The fact proved, this means improves the precision and reliability of oil remaining distribution study.
