多油层非均质复杂断块油田高效开发技术

Highly effective development technology of multi-oil layers heterogeeous complex fault block reservoir

桥口油田是一个多油层非均质复杂断块油藏,针对油田的开发状况和油藏的地质特点,近年来开展了“以油藏精细描述为基础,在原井网的基础上,以平面上局部调整(恢复)完善注采井网、纵向上层间转移调整两个剖面为手段,以控水稳油为目的”的油藏综合调整治理。进一步完善(恢复)局部井区的注采井网,强化有效注水,不断提高Ⅱ、Ⅲ类层的动用程度,使桥口油田的开发效果逐步得到改善,两个递减、综合含水得到有效的控制,实现了连续7年的稳产。

Qiaokou oilfield is multi- oil layers heterogeeous complex fault blocks reservoir. In view of the oil field development condition and the oil deposit geological characteristic. In recent years, we developed reservoir overall - adjustment government of ＂ based on fine description, in the original well pattern foundation, the partial Adjustment （restored） take the plane in consummates the inject-recovery well pattern, as the method of the during longitudinal upper formation shifts adjusts two profiles , take aim on controlled water and steady oil ＂. Further consummates （restores） the well pattern of partial well area, strengthening effectively pours water, unceasingly enhances use degree of Ⅱ, Ⅲ type of layers. Development result has been improved, decline rate, water cut has been effective controled, realized continuously stable production for 7 years.
