连续油管喷砂射孔环空分段压裂技术在苏里格气田的应用
Application of coiled tubing jet perforation separated fracturing through annulus technique in Sulige gas ifeld
摘要
Abstract
Sulige gas ifeld belongs to three low-ifelds, including low porosity, low pressure and low permeability, and requires frac-turing treatment for industrial gas. Depending on its technical advantages, coiled tubing jet perforating staged fracturing through annulus technique becomes the most signiifcant method for horizontal wells stimulation in Sulige area. Through the combination of down-hole tools such as positioned and packer, coiled tubing jet perforation separated fracturing through annulus technique can realize sand blast-ing perforation, packer stratiifcation, downloading casing in large quantities and coiled tubing accurate positioning. So several works can be ifnished by only one string trip, and has the advantages of short working cycle, low cost, full size after fracturing, etc. This paper elaborates the operating principle of this technique and the mechanism and structure of main tools in detail. The successful implement of this new process in one horizontal well in Sulige illustrate that the coiled tubing jet perforation separated fracturing through annulus tech-nique is applicable to tight gas reservoirs, providing a new and effective mean for multi-stage hydraulic fracturing of horizontal wells.关键词
