I think in this context "carry" and "contain" are synonymous (if the sand is included) but it could mean something different if the fluid is without sand. For example if it's talking about preparing the fracturing fluid and says something like "the sand is added to the sand carrier fluid before shipping" or in this case the first fluid used that is without sand.

Carry has the meaning of "move/transport/lift".

The source distinguishes fracturing fluid (破砕流体) with and without proppant particles so maybe 破運流体 or 砂支持流体 would work.

”carrier”の意味に関して ”carrier”には、”contain”の様な”含む”という意味があるのでしょうか？
