水平井裸眼分段压裂工具应用技术是提高油气藏开发产能的关键措施。从裸眼封隔器研制、工作原理、性能特点出发对苏里格气田裸眼封隔器使用进行研究,以苏东55-31H2井为例,对裸眼封隔器配套工具设计、施工过程管理、施工管控措施进行全过程应用,结果表明我国研制的裸眼封隔器分段压裂工具具有良好压裂效果和完井成效。 Horizontal well open-hole fracturing tools application technology is to improve the development of oil and gas production capacity of the key measures. Based on the research and development of open-hole packer, working principle and performance characteristics, the author studies the use of open-hole packer in Sulige gas field. Taking the well Su-dong 55-31H2 as an example, the design and construction process management, construction process, The control measures are applied in the whole process. The results show that the fractured hole-free packer developed in our country has good fracturing effect and well completion effect.
