Embodiment 1
[0031] A fracturing method for recyclable fracturing fluid used in sandstone gas reservoir fracturing construction, comprising the following steps:
[0032] a. Mix the fluid loss control agent and the recyclable fracturing fluid evenly on the ground and inject them into the formation to create fractures. The mass ratio of the fluid loss control agent to the recyclable fracturing fluid is 1%: 99%;
[0033] b. Carry out sand fracturing operations;
[0034] c. After the sand filling in the fracturing operation is completed, the blowout is controlled after the cracks are closed;
[0035] d. The flowback liquid enters the liquid storage tank after desanding and gas-liquid separation;
[0036] e. Check the viscosity of the liquid in the liquid storage tank. If it does not meet the design requirements, continue to add thickener until the viscosity meets the requirements, and supplement the fluid loss control agent to the specified concentration requirements;
[0037] f. Carry out s...
Embodiment 2
[0049] A fracturing method for recyclable fracturing fluid used in sandstone gas reservoir fracturing construction, comprising the following steps:
[0050] a. Mix the fluid loss control agent and the recyclable fracturing fluid uniformly on the ground and inject them into the formation to create fractures. The mass ratio of the fluid loss control agent to the recyclable fracturing fluid is 5%:95%;
[0051] b. Carry out sand fracturing operations;
[0052] c. After the sand filling in the fracturing operation is completed, the blowout is controlled after the cracks are closed;
[0053] d. The flowback liquid enters the liquid storage tank after desanding and gas-liquid separation;
[0054] e. Check the viscosity of the liquid in the liquid storage tank. If it does not meet the design requirements, continue to add thickener until the viscosity meets the requirements, and supplement the fluid loss control agent to the specified concentration requirements;
[0055] f. Carry out...
Embodiment 3
[0067] A fracturing method for recyclable fracturing fluid used in sandstone gas reservoir fracturing construction, comprising the following steps:
[0068] a. Mix the fluid loss control agent and the recyclable fracturing fluid evenly on the ground and inject them into the formation to create fractures. The mass ratio of the fluid loss control agent to the recyclable fracturing fluid is 2%:98%;
[0069] b. Carry out sand fracturing operations;
[0070] c. After the sand filling in the fracturing operation is completed, the blowout is controlled after the cracks are closed;
[0071] d. The flowback liquid enters the liquid storage tank after desanding and gas-liquid separation;
[0072] e. Check the viscosity of the liquid in the liquid storage tank. If it does not meet the design requirements, continue to add thickener until the viscosity meets the requirements, and supplement the fluid loss control agent to the specified concentration requirements;
