【 摘 要 】

In this paper, Using the unique advantages of streamline based (SL) flow simulation, for the first time, we have attempted to simulate waterflood strategies in Buzrgan oil field in southern Iraq and to optimize it. Therefore, in this paper the streamlines are really significant that: • The numerical calculation of the produced and injection fluid at any given time is possible for each pair of wells. • Fux pattern maps represent the significant information of the streamlines. • The runtime in the simulation of the (SL) is much less than finite-difference (FD). Using this (WAF's), it is possible to calculate the efficiency of injected wells as the proportion of injected water to the oil delivered at balance wells. With injectedefficiencies (IE) known over the field for every injector, water can be reallocated from low-efficiency to high-efficiency wells, in this way computing the assemblyfor each barrel of water injected, resulting in more sweeping and significant optimization. In addition to this, the IE chart has been given obvious visual of the reservoir management such as (eg, the changes of the wells with low IE to the injection wells.
