摘要

威远页岩气区块储层致密,天然裂缝局部发育,储层非均质性较强,常规的水平井分段压裂技术无法满足产能需求。针对该问题,以威AH1平台为例,基于地质工程一体化技术思路,综合地质属性模型和地质力学模型,建立了威AH1平台的一体化压裂模型。利用模型对压裂排量、压裂液量、砂比、分簇数量、支撑剂配比与注入方式进行了分析,确定了压裂施工最优化参数。该研究结果在威AH1平台应用了8口井,与压裂前相比,日产气量提高了30%。该研究可为威远地区页岩气一体化开发提供技术支持。

Abstract

Due to the tight reservoirs in the Weiyuan shale gas block, the local development of natural fractures, and the strong reservoir heterogeneity, the conventional horizontal well staged fracturing technology cannot meet the productivity demand. To address the problem, taking Wei AH1 platform as an example, an integrated fracturing model for the Wei AH1 platform was established based on the technical idea of integrated geological engineering, geological property model and geomechanical model. The model was used to analyze the fracturing displacement, fracturing fluid volume, sand ratio, number of clusters, proppant ratio and injection method, and to determine the optimal parameters of fracturing operation. The research results were applied to 8 wells on the Wei AH1 platform, and the daily gas production was increased by 30% compared with that before the fracturing. This research can provide technical support for the integrated development of shale gas in Weiyuan Area.

Key words： shale gas; volume fracturing; artificial fracture network; support area; Weiyuan Area
