Problems solved by technology

Diesel-based or kerosene-based guar gum suspensions have a low flash point, which poses a safety hazard. After mixing with water, the viscosity will rise sharply, causing the pump pressure to be too high, and the construction friction is relatively large. It is only suitable for special formations.

preparation example Construction

[0023] Specifically, see figure 1 , the preparation method of a kind of super guar gum suspension that the embodiment of the present invention provides comprises the steps:

[0024] Step 100: mixing ethylene glycol butyl ether and propylene glycol phenyl ether to generate a primary suspension;

[0025] Wherein, this step 100 is used to generate primary suspension as the basic step of preparing super guar gum suspension, to suspend super guar gum, in this step 100, please refer to figure 2 , can specifically include: step 101, select a portion of ethylene glycol butyl ether; step 102, select a portion of propylene glycol phenyl ether; 1:0.01~1:10 mixing to generate the primary suspension. In this step 100, a primary suspension is generated by mixing ethylene glycol butyl ether and propylene glycol phenyl ether in a mass ratio range of 1:0.01 to 1:10, while ensuring that the primary suspension can suspend the super guar gum, so that through the present invention Example Duri...

Abstract

The invention discloses super guanidine gum suspension and a preparation method thereof. The preparation method comprises the steps: mixing butyl cellosolve and phenoxy-1-propanol to generate primary suspension; adding citric acid into the primary suspension to adjust a dissolving environment of the super guanidine gum when in continuous mixing; adding wetting dispersing agent into the primary suspension after the citric acid is added to adjust the dispersing time of the primary suspension; thickening the primary suspension after the wetting dispersing agent is added to generate secondary suspension; grinding the secondary suspension to form the super guanidine gum suspension. The super guanidine gum suspension has good storage stability and rapid dissolving performance; a fracturing fluid system prepared by adopting the suspension is relatively low in surface and interface tension; when the super guanidine gum suspension is used for preparing water-based fracturing fluid, the viscosity and application performance are not influenced.

Description

technical field [0001] The invention belongs to the technical field of water-based fracturing fluid, in particular to a super guar gum suspension and a preparation method thereof. Background technique [0002] In the existing water-based fracturing fluid technology, the water-based fracturing fluid mainly adopts intermittent dosing technology, but due to the high molecular weight of super guar gum powder, it is easy to form fish eyes or agglomerates during the dissolution process, which affects water-based fracturing. Liquid viscosity and performance. Instant super guar gum powder can avoid the generation of fish eyes or lumps, but for the continuous liquid dosing process, its measurement becomes difficult, especially in the offshore construction process, due to high wind and waves, the accuracy of continuous measurement cannot be guaranteed. Prepare the guar gum powder into a suspension, and realize continuous metering and continuous dosing through the metering pump casing...
