碳酸盐岩储层酸压工艺技术综述

A REVIEW ON WATER SHUTOFF AND PROFILE MODIFICATION IN STEAM HUFF PUFF VISCOUS OIL WELLS AT WEST HUANXILIN OIL FIELDS

本文介绍了压裂酸化（即酸压）技术与基质酸化技术的区别和各自的特点，综述了七大深度酸压技术，讨论了每种技术的特点及应用范围。还介绍了针对碳酸盐岩储层的不同特性发展和应用的两大特殊工艺技术。文中强调指出，多级注入闭合酸压技术已成为９０年代以来对低渗及特低渗油气藏进行增产改造的主流技术。

This paper reviews the water shutoff and profile modification treatments performed in steam huff puff production wells of viscous crude oil reservoirs in West Huanxilin, Liaohe: the features; the seven chemical water controlling agents used in last two years; the technology of treatments both for profile modification before steam injection and water shutoff within a production cycle; and the field results.
