引言在油田开发的实际工作中,采用面积注水的开发方式,逐步得到人们的重视。这是因为该开发方式较能适应油田的非均质性特点,并且具有较高的采油速度和最终的采收率。很多边外或边内切割注水的油田,在开发中期或后期为了提高油田全面开发的效果,也常常经调整,而转化为不同方式的面积注水。由此可见,对于不同面积注水方式的水动力学计算方法的研究,就显得很有必要了。M.马斯克特和 H.柯鲁特尔,对于面积注水的直线系统、五点、七点和九点系统,利用源汇反映和势能叠加原理,进行严格的数学推导,得到计算油井见水前的产量 Introduction In the practical work of oilfield development, the development of area waterflooding has gradually gained people’s attention. This is because the development method is more adaptable to the heterogeneity of oilfields and has higher oil recovery rate and ultimate recovery. Many oilfields that cut and inject water outside or inside the boundary are often adjusted to convert different areas of waterflooding in the mid- or late-development phase in order to enhance the overall oilfield development. It can be seen that it is necessary to study the hydrodynamic calculation method of water injection with different area. M. Musket and H. Kluterrell, for a straight line system of area injection, a rigorous mathematic derivation using the principle of source and sink and potential energy superposition for a five-point, a seven-point and a nine-point system, Before the production
