Sabei development zone, after 46 years of water developmenting, has now developed into the late high water cut. The representative test block of Sabei development zone was analyzed and provided the basis for the further development and adjustment. The results show that, well is poor adaptability serious interference between layers, complex relationship between injection and production, all these questions in the test block are not conducive to carried out the effective control of injection and production. Through numerical simulation way and history matching, the remaining oil saturation of test block is proposed,it will ensure the next step oilfield development.%萨北开发区经过46年的注水开发,目前已进入特高含水开发后期.选取萨北开发区中具有代表性的试验区块进行研究,为下一步开发调整提供依据.研究结果表明:试验区目前井网的适应性差,层间干扰严重,注采关系复杂,不利于有效地开展注采控制.在严格的历史拟合基础上,应用数值模拟方法,最终提出了目前试验区块实际剩余油饱和度图,为下一步油田开发提供了可靠依据.
