连续油管压裂技术资料(国外英文资料) Thirtieth volume first development project 1 Hydraulic injection annular fracturing technique for coiled tubing Wang Tengfei, Xu Yun, Jiang Jianfang, Tian Zhuhong, Ding Yunhong Langfang branch of Research Institute of petroleum exploration and development of China Wang Tengfei. The coiled tubing annulus Hydrajet fracturing technology. Natural gas industry, 2010, 30 (1): 65 - 67. Hydraulic injection fracturing of coiled tubing is an effective method to solve the problem of vertical multi layer fracturing in China On the basis of comparison of two methods of coiled tubing transmission fracture and annular fracture, the hydraulic injection annulus The principle, construction procedure, calculation of frictional resistance, superiority and limitation of fracturing technology are analyzed comprehensively. The results show that the annular fracture method is through sand blasting The combination of perforating and annular sand adding can widen the application depth of coiled tubing, improve the utilization ratio of existing small size coiled tubing equipment in China, increase the life of nozzle and increase construction Displacement, which has higher field applicability and operability. The research results are as follows: introduction of foreign coiled tubing to solve the problem of domestic gas reservoir partial pressure modification, and Variable concepts have laid the foundation for large-scale hydraulic fracturing of coiled tubing hydraulic jets.
