摘要

南川区块二叠系茅口组泥灰岩气藏储层低孔低渗、碳酸盐岩含量高、裂缝不规则发育但连通性差、地层非均质性强,常规酸压技术直接进行储层改造的方法存在酸岩反应迅速、溶蚀距离有限等问题。结合该区块茅口组典型地质特征,开展了胶凝酸液实验测试与评价,筛选了以“多级交替注入酸压+闭合酸化”为主的增黏性强、配伍性好、稳定可降解的胶凝酸液体系,并在南川区块DS1HF井首次成功试验应用,取得了10 mm油嘴生产制度下,测试稳产气量23.05×104 m3/d的良好效果,验证了该项工艺技术在泥灰岩气藏中的应用可行性,对国内同类气藏的开发有良好的借鉴和推广应用价值。

Abstract

The marl gas reservoir of the Permian Maokou Formation in the Nanchuan area is characterized by low porosity and low permeability, high carbonate content, irregular fracture development, poor connectivity and strong heterogeneity. The conventional acid fracturing technology used to transform the reservoir directly has the problems such as the rapid reaction of acid under the reservoir conditions, and limited dissolution distance. Based on the typical geological characteristics of the Maokou Formation in this area, experimental testing and evaluation of the gelling acid system has been selected. A gelling acid system with strong viscosity, good compatibility stability and degradability in the mode of “multistage alternating injection of acid fracturing+closed acidizing” is screened. The gelling acid system has been successfully applied in Well-DS1HF in Nanchuan area for the first time, and the stable production is 23.05×104 m3/d under the production system of 10 mm nozzle.The good results verify that the application of this technology in marl gas reservoirs is feasible. It has a good reference and application for the development of similar gas reservoirs in China.
