摘要
尕斯库勒E31油藏已进入中高含水期,常规静态储层地质模型已不能满足开发需要,流动单元从渗流特征上对储层进行刻划可有效指导后期开发调整。研究表明该区渗透率、渗透率与孔隙度的比值两个参数与吸水强度相关性较好,可依此描述本区流动单元渗流差异。尕斯库勒E31油藏辫状河三角洲前缘亚相储层可划分为四类流动单元。流动单元平面分布受沉积环境控制,纵向分布规律受沉积环境与沉积韵律控制。
E3^1 reservoir of Gasikule has entered into middle - high water cut stage, and the normal static reservoir geo-logical model can not meet the need of development. The study of the percolation characteristcs of reservoir can guide the further development adjustment. Research results show that permeability and the ratio between permeability and porosity are consistent with the water absorptivity. Therefore, the two parameters can be used to describe the flow difference of flow units. Four kinds of flow units were classified in the braideddelta front subfacies reservoir of E3^1 reservoir in Gasikule Oil-field. The plane distribution of flow unit was controlled by the sedimentary environment. And the vertical distribution was controlled by sedimentary environment and sedimentary rhythm.
