摘要： A method of using a slurry-like fracturing fluid for hydraulic fracturing in an unconventional reservoir: injecting the slurry-like fracturing fluid into the unconventional reservoir, the slurry-like fracturing fluid comprises a particulate portion and a slurry water, the particulate portion comprises a solid acid component, injecting the slurry-like fracturing fluid is operable to generate a network of fractures, the slurry-like fracturing fluid is operable to reduce a reservoir temperature from a resting reservoir temperature, permitting the slurry-like fracturing fluid to cure into a permeable bed, allowing the reservoir temperature to return to the resting reservoir temperature to trigger the hydrolysis of the solid acid, hydrolyzing the solid acid to produce a liquid acid, and stimulating the network of fractures with the liquid acid to increase permeability of the permeable bed in the network of fractures in the unconventional reservoir, the increased permeability operable to create a sweet spot.

摘要： A method of increasing a stimulated reservoir volume in a wellbore in a gas-containing formation includes the steps of mixing an exothermic reaction component to achieve a pre-selected solution pH, the exothermic reaction component is operable to react at a wellbore temperature to generate a pressure pulse, mixing the exothermic reaction component with a viscous fluid component operable to fracture the gas-containing formation to create fractures, and a proppant component, the proppant component carried to the fractures by the viscous fluid, the proppant component comprises a proppant operable to hold open the fractures, to form a fracturing fluid, injecting the fracturing fluid into the wellbore in the gas-containing formation to create fractures, and generating the pressure pulse when the exothermic reaction component reaches the wellbore temperature, the pressure pulse operable to create auxiliary fractures, wherein the auxiliary fractures create a fracture network, the fracture network increases the stimulated reservoir volume.
摘要翻译：增加含气体地层中的井眼中刺激储层体积的方法包括以下步骤：将放热反应组分混合以达到预先选择的溶液pH，放热反应组分可操作以在井筒温度下反应生成将放热反应组分与可操作以使含气体地层断裂以产生裂缝的粘性流体组分混合，以及支撑剂组分，支撑剂组分由粘性流体承载到裂缝中，支撑剂组分包含可操作以打开裂缝，形成压裂液，将压裂液注入含气地层的井筒中，产生裂缝，并在放热反应组分达到井眼温度时产生压力脉冲，压力脉冲可操作地产生辅助骨折，其中辅助骨折产生骨折网，骨折网工作增加了受刺激的储层量。
