摘要： 辽河滩海油田海南3 断块是一个层状边水岩性构造油藏,经过10 年的注水开发,开发矛盾逐渐显现。虽然进行了系列油井堵水和注水井调整,取得了一定的效果,但含水上升逐年加快,水驱效果变差。寻找新的注水方式以改善水驱开发效果成为一项主要工作。在滩海油田地质基础上选取有利区域进行试验,评价周期注水可行性,首次利用油藏计算公式进行周期注水参数计算,并将计算结果应用于实际,进行周期注水试验,并取得增产改驱的良好效果,为辽河滩海油田下步周期注水的规模实施奠定了基础。

Abstract: Hainan-3 fault block in Liaohe Tanhai oilfield is a layered lithologic-structural reservoir with edge water. Following 10-year waterflood development, the inconsistency of development is more and more emerging. In despite of conducting a series of producer water plugging and injector adjustment and obtaining some responses, the year-by-year water cut increasing has caused it to become poor in water drive effectiveness. Searching for new water flood mode to improve the water drive response becomes a necessary task. This paper selects favorable test area based on the geologic feature of Tanhai oilfield for first feasibility evaluation of its cyclic water flood, parameter estimation and field test. The good results for increasing production and improving displacement response provide foundation for implementation of next large-scale cyclic water flooding in this field.

Key words: Tanhai oilfield, water wet, middle-low permeability, heterogeneity, cyclic water flood, feasibility analysis, parameter estimation
