| 摘 要： | 水平井分段压裂技术目前已在国内大庆、辽河、华北、西南等油气田进行了广泛的应用，但主要用于垂深小于 4 000 m 的储层。顺9 井区为埋藏深、物性差的砂岩储层，常规直井压裂增产幅度有限，无法获得持续的工业油流，需 通过水平井的分段改造增加泄油面积，提高单井产能。而顺9 井区埋藏深、闭合压力与破裂压力高等特点给水平井的 分段改造工具、液体体系和工艺技术方法的优选带来一系列的难度，在分析国外深层水平井分段压裂工艺技术的基础 上，结合顺9 井区的储层特点和国内水平井分段改造技术能力，从水平井分段改造工艺与工具、液体体系及裂缝参数 等方面进行优化研究，初步形成了适合顺9 井区的水平井分段压裂工艺技术。 |

| Abstract: | Horizontal Staged fracturing technology has been widely used in oil and gas fields in Daqing，Liaohe，and Huabei and Xi′an in China，but it is mainly used in reservoirs with vertical depth of less than 4 000 m. Conventional vertical well fracturing stimulation has limitations in production increase，and cannot sustain the industrial oil flow as sandstone reservoirs in Shun – 9 well area，which has super depth reservoirs and their poor physical properties. So there has great needs to increase the drainage area and improve well productivity through horizontal staged fracturing technology. But the characteristics of super buried depth，high closure pressure and fracture pressure of Shun – 9 well bring a series of difficulties for the staged fracturing technology of transformation tool selection，liquid systems and technology method. Based on the analysis of foreign fracturing technology deep horizontal well of Shun – 9 well reservoir characteristics and an domestic technical capabilities horizontal well transformation，the horizontal well transformation process and tools，liquid systems and fracture parameters are optimized for developing the horizontal well fracturing technology for Shun – 9 well area. |
