考虑平面非均质的低渗透油藏产能计算方法
PRODUCTIVITY CALCULATING METHOD OF THE LOW-PERMEABILITY OIL RESERVOIRS CONSIDERING THE PLANAR HETEROGENEITY
摘要
Abstract
In view of the geological conditions and current production dynamics of Yong-1 Member Sha-4 conglomerate oil reservoir,on the basis of the hydropower similarity principle and equivalent seepage resistance method,considering the threshold pressure gradient and planar heterogeneity of the oil reservoir,the calculating method of the changed productivity with the time was established and moreover compared and verified by the actual production.Taking the changed law of the producer-injector interwell permeability and linear variation of the reservoir thickness as the examples,the influences of different planar heterogeneous distributions on the productivity were studied.The results show that for the low-permeability heterogeneous oil reservoir,under the condition of the constant injection-production pressure,the well arrangements of "High injection and low production" (Injection at the higher permeability end and production at the end) and "Thick injection and thin production" (Injection at the thicker end and production at the thinner end) are more conducive to the improvement of the reservoir productivity and the enhancement of the recovery.关键词
