摘要:
针对目前加砂压裂增产新工艺水力喷射分层压裂加砂对压裂液性能新的特殊要求,在实验室开展了满足该新工艺施工要求的压裂液配方体系的研究,对优化压裂液液体配方、交联剂组成、交联比等进行了室内性能试验。研究出满足该新工艺的压裂液配方和现场应用技术。室内性能评价表明,研制的压裂液满足水力喷射分层压裂加砂对压裂液高剪切后携砂的要求,并在四川须家河广安、合川等区块大斜度井、水平井的水力喷射分层压裂施工中得到成功应用,累计增加天然气产量11.1365×104 m3/d。

Abstract:
This paper presents a new sand fracturing technology of hydraulic jet,which needs fracturing fluids with new special performances,so the fracturing fluid system for the new process was studied in laboratory by optimizing the formula of fracturing fluid system,cross-linking agent composition,crosslinking ratio,and etc.A developed fracturing fluid formula and field application technology meets the new process.The lab performance evaluation shows that the fracturing fluid can meet the requirement for carrying sand after shearing highly fracturing fluid by hydraulic jet layer and sand fracturing.The technology has been successfully applied in Guangan,Hechuan and other blocks of Xujiahe in Sichuan high-angle wells,horizontal well hydraulic fracturing jet layer.The natural gas production increases accumulatively 11.1365×104 m3/d.
