压裂——水力泵排液求产联作工艺在吉林油田的应用

Application of Combing Tech of Unloading with Fracture-Hydraulic Pump and Finding Production in Jilin Oilfield.

压裂-水力泵排液求产联作是将水力泵举升排液工艺与压裂施工的有机结合,实现一趟管柱完成压裂施工和水力泵排液求产。缩短了试油排液周期、减轻了劳动强度,发挥了水力泵举升排液中排液能力强、工作制度可调、可随泵测压取样等特点。经在吉林油田红75-8井应用, 6 d完成水力泵排液求产工作,达到设计要求。

Tech of unloading with fracture-hydraulic pump and finding production is the organic integration of lifting with hydraulic pump and fracture operation which makes true completing two jobs by only one testing string, has features of shortening oil test and unloading cycle, lightening working intensity that exerts the advantages of big lifting and flowing back capacity of hydraulic pump, adjustable work system and acquiring pressure with pump. By application of this tech in Hong75-8 well in Jinlin oilfield, unloading with fracture-hydraulic pump and finding production has been done in 6 days and design requirement is reached.
