摘要
由于常规Y341套管封隔器分段压裂,压裂液返排不够通畅,影响了返排及压裂改造效果。通过调研评价全通径压裂工艺技术,优选连续油管拖动底封分段压裂工艺、K344封隔器分段压裂工艺等全通径分段压裂工艺进行现场试验。介绍了这两个工艺的原理、特点及现场试验情况,对现场试验结果进行了分析。
For segregated fracturing with conventional Y341 casing packer,flow-back of fracturing fluid is not smooth,which influences the flowback effect and fracturing result. Through the investigation and evaluation of full bore segregated fracturing technology,field experiment of full bore segregated fracturing technology of the optimized coiled tubing dragging and the bottom sealing segregated fracture,and K344 packer segregated fracture has been conducted. The paper introduces the principle,characteristics and field test of the two process and analyzes the experimental results.
