Abstract: In the development of massive oil pool of normal cyclothem with sufficient reservoir energy and active edge and bottom water drive,the primary means of controlling the appearance of secondary bottom water and the intervention of water coning is to perforate only the upper part of the reservoir at limited interval so as to prolong the period of production and increase the amount of output without water cut.In the course of development,reasonable control of pressure difference of production should be accompanied by a higher intensity of fluid withdrawal at the wells around the edge of the pool than that in the interior wells as far as possible in order to abate the speed the channelling of edge and bottom water along the bottom of the pool.When secondary bottom water appears and serious water coning occurs near the bottom of the hole,a part of oil wells in the net pay section may be selected for water in jection to check the expansion of secondary bottom water and the progress of bottom water coning.From our experience,this way of development has contributed greatly to the reasonable utilization of reservoir energy and improvement of efficiency of development that end in a higher ultimate rate of recovery.

摘要： 本文介绍了大港油田港东六断块和羊二庄油田的块状砂岩油藏注水开发后,很快地由原始半底水变成全底水的情况,从而使水锥带来的油井减产进一步扩大。文章概述了采取控制射孔井段、合理安排内外油井的采液强度及部分井在纯油段注水等措施后取得了显著效果。
