| 摘 要： | 由于塔里木盆地哈拉哈塘区块碳酸盐岩储集层酸压形成的人工裂缝与天然缝洞系统沟通,从而提高了油井产量。综合运用酸压施工曲线分析法和裂缝导流能力曲线分析法对该区块近年来20多口酸压井的酸压改造效果进行评价和分类,研究了不同曲线对应的碳酸盐岩储集层缝洞发育情况和分布规律,分析了人工裂缝沟通天然缝洞系统的各种情况。研究结果可用于正确指导酸压设计优化和后期开发。

| Abstract: | Acid fracturing is the main method for carbonate reservoir transformation in Halahatang block,aiming at communicating acid-etching fractures and natural fractures and increasing the oil production.This paper analyzes the data from more than 20 acid-fracturing wells in Halahatang block,evaluates and classifies the effects or responses of acid-fracturing transformation by means of acid fracturing construction curve analysis and fracture conductivity curve analysis,including the research of the fractured-vuggy carbonate reservoir development and distribution corresponding to the different curves and the communication between acid fractures and natural fractures system.The results could be applied to guide acid fracturing design and optimization as well as later development. |
