裂缝网络模型的建立及其在任丘潜山油藏中的应用

裂缝网络参数是潜山裂缝油藏开发和剩余油挖潜不可缺少的重要参数.针对潜山裂缝油藏依据油田区资料无法建立裂缝网络模型这一特点,提出了通过建立相似露头区裂缝网络模型来实现这一目的的思路和方法,并应用到任丘潜山油藏中.结果与开发动态资料吻合得非常好,说明利用相似露头是建立潜山裂缝油藏裂缝网络模型的有效手段.

Establishment of the fracture network model of analogous outcrop and its application in the buried hill reservoir in Renqiu

The fracture network parameters are of importance to the development and the remaining oil potential-tapping of buried hill fracture reservoir. A set of systematic idea and methodology for establishing the fracture network model of the buried hill fracture reservoir by establishing the fracture network model of analogous outcrop zone are put forward since the fracture network model of the buried hill fracture reservoir cannot be established only based on the data from oilfield zone. And the methodology is applied to the buried hill fracture reservoir in Renqiu. The application result tallies well with the dynamic development data of the reservoir. It is shown that the analogous outcrop modeling is a very effective means to the establishment of the fracture network model of buried hill fracture reservoirs.
