Abstract

The invention discloses a fracturing fluid friction resistance testing device and method.The device comprises a material supply device and M friction resistance testing channels.The fluid outlet of the material supply device is connected with the first port of each friction resistance testing channel through an input pipeline.The second port of each friction resistance testing channel is connected into the material supply device through an output pipeline.The first port of each friction resistance testing channel is provided with a front pressure transmitter, a front adjustable flow valve and a flow meter.The second port of each friction resistance testing channel is provided with a rear pressure transmitter and a rear adjustable flow valve.The M friction resistance testing channels include at least one horizontal circular channel, at least one spiral circular channel, at least one horizontal fracture channel, at least one S-shaped fracture channel and at least one square wave type fracture channel which are connected in parallel.Therefore, the technical problem that in the prior art, the underground space internal fracturing fluid friction resistance theory is lack of reliable indoor data is solved, and fracturing efficiency can be easily improved.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to a fracturing fluid friction test device and a test method. Background technique [0002] The proportion of coalbed methane and shale gas in the national energy structure is increasing year by year, and their role in the national economic development is becoming increasingly prominent. As a practical and effective method, hydraulic fracturing has been applied in conventional oil and gas development, and has been widely used in coalbed methane and shale gas exploitation. As a medium for developing underground gas reservoirs, fracturing fluid plays the role of fracturing formations, changing formation pressure, creating fractures and carrying sand, and generating gas production channels. Because coalbed methane and shale gas are buried deep underground, especially shale gas is often located two to three kilometers underground, the pressure loss of the fracturing fl...
