摘要
洛带气田遂宁组气藏以致密低渗的砂泥岩互层为主,低渗致密砂泥岩互层气藏储层具有多个砂泥岩薄互层、在纵横向上非均质性强等特点。根据洛带气田遂宁组地质、工程情况,结合川西压裂工艺实践,建立了压裂优化设计分类标准,推荐采用合层压裂为主,分层压裂为辅的多层压裂工艺技术。对于同一气藏而言,砂层间距<10m,采用合层压裂工艺,砂层间距大于10m,推荐采用分层压裂。压裂优化设计的基本原则是分类对待,科学设计,精心实施。气藏内不同的井都要进行精心设计,才能达到高效开发的目的,实现气藏的高效压裂开发。
The gas reservoir in Suining group of Luodai gas field is low permeability sand and mud interstratification, its heterogeneity is very strong. On the basis of the characters of the reservoir, the classification criteria of fracturing optimization design was established and the optimization design was done to different reservoir. Meanwhile, the corresponding technical measures were adopted to actualize high efficiency fracturing development of gas reservoir.
