对于水驱开发的油田来说,如何预测油田的高产稳产期限和产量的递减规律,乃是油田开发工作中的一个十分重要的课题。但是,这个课题的解决,常常遇到许多复杂的理论问题和实际问题,因而不可能得到一个切实有效的方法。本文基于苏联23个接近开发完毕的水驱砂岩油田资料,利用实际资料的统计办法,从中找到某些固有的规律性,用来解决水驱油田的高产稳产期限和产量递减的预测问题,以供实际工作中参考。(一)开发资料的统计研究方法
For oilfields developed by waterflood, how to forecast the period of high and stable production and the decreasing law of output is one of the most important issues in oilfield development. However, the solution to this issue often encounters many complicated theoretical and practical problems, so it is impossible to obtain a practical and effective method. Based on the data of 23 near-developed waterflooding sandstone oilfields in the Soviet Union, this paper finds some inherent regularities by using the statistical methods of actual data and solves the prediction problems of the high and stable yield and diminishing production of waterflooding oilfields for Reference to the actual work.
