Abstract

The invention discloses a liquefied petroleum gas anhydrous fracturing fluid preparation device and method and belongs to the technical field of oil and gas exploitation. The device comprises a reactor, a stirring system, a protective sleeve, a quantification system and a safety protection system. A first connector is communicated with the reactor through a first valve. A second connector is communicated with the reactor through a second valve. A third connector is communicated with the reactor through a third valve. The protective sleeve wraps the reactor. The quantification system is communicated with the reactor through the second connector and is used for injecting liquefied petroleum gas and additives into the reactor in an order. The stirring system is arranged in the reactor and is used for stirring the liquefied petroleum gas and additives fed in an order. The safety protection system is communicated with the reactor. The device and method solve the problem that the prior art cannot prepare a liquefied petroleum gas fracturing fluid at the normal temperature.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to a preparation device and method for anhydrous fracturing fluid of liquefied petroleum gas. Background technique [0002] In the exploration and development of natural gas, unconventional gas reservoirs such as shale gas and tight gas have increasingly become the main force of natural gas development. Unconventional gas reservoirs are generally exploited in the volumetric fracturing mode with large liquid volume and high displacement, which requires a large amount of water resources and also poses certain risks to the environment. Therefore, liquefied petroleum gas is used in fracturing without water. The replacement of conventional fracturing fluid systems by fracturing fluids has gradually become an inevitable trend of technological development. [0003] Because liquefied petroleum gas fracturing fluid is gaseous under normal conditions, conventional fracturing...
