摘要
文章针对塔里木和田河气田石炭系和奥陶系碳酸盐岩储层的渗流能力、伤害程度、天然裂缝发育状况等资料的分析以及目前国内现有酸化技术能力和酸液体系的综合考虑 ,对适合该气田的深度酸压工艺技术进行了优选。对常规酸蚀导流试验、闭合裂缝酸蚀导流能力试验、闭合压力对酸蚀导流能力的影响、施工排量对有效酸蚀作用距离与酸液浓度分布的影响、砂岩酸化优化设计与施工工艺参数优选、和田河气田酸处理效果预测分析等进行了研究。
On the basis of analyzing the capacity of fluids through porous media,the damaged degree and the developed state of the natural fractures of Carboniferous and Ordovician carbonate reservoirs in Hetianhe gas field in Talimu basin and in view of the ability of existing acidizing technology and acidizing fluid system at home,the depth acidizing technology suitable for this gas field is optimized and the conventional acid etched conductivity test,the test of the acid etched conductivity in closed fractures,the influnce of closure on acid etched conductivity,the influence of flow rate on the effective acid etching action radius and on the distribution of acid fluid concentration,the optimal design for acidizing of sandstone,the optimization of operating parameters and the predicion and analysis of the acidzing treatment effect in Hetianhe gas field,etc.are studied.
