摘要
油层的平面非均质是影响油藏注水开发效果的重要因素之一。依据注水后油井见效、见水的时间和特征,计算出两井间非均质系数,并据此调整油井产液量,使井组内不同井距、不同油层厚度的油井,在大致相同的时间内见注入水,最大限度地克服了平面非均质性给油藏注水开发造成的影响。将此方法用于渤中25-1南油田的动态管理,取得了较好的效果。
The lateral heterogeneity of an oil reservoir is one of important factors affecting its waterflood response. Based on the time and characteristic of response and water breakthrough in an oil well following waterflood, the heterogeneous coefficients between two wells can be calculated, by which the mass production is optimized, allowing oil wells with different well spacing and core intersection in a well group to realize the minimum affect from such a lateral heterogeneity to the reservoir. This method has been applied to BZ25-1S field in performance management and the obvious effectiveness has been achieved.
