摘　　要：在油藏注水开采过程中,对于和注水井不连通的油层和与水井连通性差的油层来说,地层能量无法得到补充或补充缓慢,致使开发效果极差,经济效益低。层间注水吞吐开发模式可以补充地层能量,恢复地层压力,通过多周期的吞吐开采,可以提高剩余油的采收率。运用数值模拟技术对该方法进行了研究,结果证明该方法简单易行,可以提高此类剩余油的采出程度。During water flooding the formation energy of oil reservoirs disconnected or poorly connected to injectors cannot be complemented or complemented slowly. For this reason the development results will be not good with low economic benefits. The interlayer water flood mode of huff and puff can complement formation energy and build up formation pressure, and then oil recovery factor will be improved through multi cyclic huff and puff development. According to numerical simulation, this technology is simple and easy to practice with improved degree of reserve recovery.
