摘要

摘要: 为满足页岩气高效化、清洁化生产的需求，采用反相乳液聚合制备乳液状疏水缔合聚合物ASNP，与自制增效剂SD-Z复配形成页岩用乳液型超分子压裂液SMF-1。该体系满足现配现用需求，无需额外添加剂，仅改变加量就能实现滑溜水、线性胶、胶液的自由切换。SMF-1滑溜水体系具有优异的降阻效果，0.08%加量下对清水和返排液的降阻率在70%左右，抗盐能力高达10000 mg/L。SMF-1胶液体系具有良好的耐温抗剪切性能，0.6%的SMF-1胶液在110℃、170 s^-1下剪切120 min，黏度始终保持在120 mPa·s以上。SMF-1压裂液属于低黏高弹流体，具有良好的携砂性能，其破胶液黏度低于1.5 mPa·s，残渣含量仅为12.8 mg/L，对岩心伤害率低至11.8%。现场应用切换方便，性能稳定，加砂强度高于同井邻段和邻井同段。

Abstract: To satisfy the needs of producing shale gas efficiently and cleanly, anemulsion-like hydrophobic association polymer ASNP was developed through inverse emulsion polymerization. The ASNP was then compounded with an extender SD-Z to produce an emulsion supramolecular fracturing fluid SMF-1, which can be prepared at the moment of using, without the needing of extra additives. Changing the concentration of ASNP, the fracturing fluid can be turned into slick water, linear gel or colloidal solution. SMF-1 slick water has excellent drag reducing ability, fresh water and fracturing fluid flowed back containing 0.08% SMF-1 have their drag reduced by about 70%, and their salt resistance can be 10000 mg/L. SMF-1 colloidal solution has excellent high temperature and shearing performance, 0.6% SMF-1 solution sheared at 110 ℃ and 170 sup>-1 for 120 min has viscosity that is at least 120 mPa·s throughout the test process. SMF-1 fracturing fluid is a fluid with low viscosity, high elasticity and good sand carrying capacity. SMF-1 fluid after gel breaking has viscosity that is less than 1.5 mPa·s, and the residue content of the gel breaking fluid is only 12.8 mg/L. In core test with the SMF-1 fracturing fluid, permeability impaired by the SMF-1 fluid is as low as 11.8%. In field application, SMF-1 can be switched to different fluids with stable properties, and the sand content is also higher than the fracturing fluid used in the offset section of the same well and in offset wells.
