摘要

针对Eagle Ford页岩凝析气井压裂开发,建立基于三线性流理论的数学模型.对生产井动态进行历史拟合,获取典型页岩及压裂裂缝参数,开展压裂改造外区产能贡献分析.结果表明,压裂改造外区对页岩凝析气井产能具有一定的贡献,且随着基质渗透率的增加产能贡献增大.在生产前5年,40 m以内的外区范围对产能有一定贡献,而且主要贡献在20 m范围以内;生产30年,外区对产能的贡献集中在60 m内.

Abstract

Taking typical condensate shale gas well in Eagle Ford as an example,a trilinear flow mathematical model is established,and the shale property parameters and hydraulic fracture parameters are derived based on the history match of production data.Thus the production contribution of outer region of stimulated reservoir volume was analyzed.Results show that the outer region can supply oil and gas to well and the production contribution of the outer region increases with shale matrix permeability.In the first five years production,the contribution area of outer region is within 40 m and the most contribution is with 20 m.In the thirty years production,the contribution area of outer region is within 60 m.
