碳酸盐岩储层深层酸压技术综述

Summary of Acid Fracturing Technology in Deep Carbonate Reservoirs

目前酸压改造是碳酸盐岩油气藏建产、投产和增产的主要技术手段,而深层碳酸盐岩储层具有埋藏深、岩性纯、地温高等特点,其酸压改造与普通酸压有所不同。文章概述了近年来国内外广泛应用的一些深层碳酸盐岩储层的酸压技术,介绍了酸压改造的目的和特点,以及各种酸压技术的作用原理、技术特点、适用范围与存在的问题,分析了目前酸压改造面临的两个难点。

Acid fracturing is the main technique to initiate and enhance production of carbonate reservoirs. Because of the characteristics such as deep embedded, pure lithology and high ground temperature depth carbonate reservoir holds, it's acid fracturing is different from ordinary ones. Various carbonate depth acid fracturing applied in world recent years are reviewed. The aim and overall characteristics of acid fracturing are instructed first, then their action mechanism、technology characteristics、applicable scope and problems existed of various techniques are introduced, the two challenges we faced are analyzed finally.
