针对水平井裸眼压裂技术的研究,对大庆深层与直井压裂对比取得了更好的产能,总结在大庆油田的深层气井中水平井裸眼滑套分段压裂技术的应用和效果。通过水平段及裂缝参数优化,和打开滑套,连续逐层进行压裂改造,建立一套适合大庆深层气水平井裸眼滑套分段压裂技术,实现提高该类储层压裂工作效率和压后产能。
Aiming at the research on the open hole fracturing technology of horizontal well, the paper compares the fracturing of deep and vertical well in Daqing with better productivity, and summarizes the application and effect of the split-fracturing technology of horizontal well open hole sleeve in the deep well of Daqing Oilfield. Through the optimization of the horizontal section and the crack parameters, and opening the sliding sleeve, the fracturing transformation is continuously carried out layer by layer, and a set of staged fracturing technology suitable for the naked-eye sleeve in Daqing deep gas horizontal well is established to improve the working efficiency of the fracturing in this type of reservoir. Post-production capacity.
