Abstract
The invention discloses a method for preparing easily-dispersible dustless guar gum granules. The method is characterized in that the guar gum granules are prepared from guar gum powder or modified guar gum powder by the processes of surface treatment, adhesion, granulation, drying, screening and the like, and the structure of the guar gum granules can be a spherical granular shape, an elliptic granular shape, a flat granular shape, a long granular shape or a square granular shape. By adopting the porous granular guar gum prepared by the method, dust injury can be reduced in the using process, constant-dissolving ingredients are added, so that the guar gum granules can be quickly dispersed in water and quickly hydrated and becomes sticky, namely generation of 'fisheye' of the guar gum in water can be avoided, and the viscosity of the guar gum can be quickly released.
Description
Technical field
The invention belongs to the preparing technical field of modified guar, relate to the preparation method of a kind of easy dispersion without dust guar gum particle.
Background technology
Fracturing technique is the important means of low permeability oil and gas field effective exploitation, and at present and from now on, different modified guar will remain most important oil-gas field fracturing liquid thickening material.Usual various modified guar is powdery, and in the process with slurry at transport and pressure break scene, dust is serious, not only causes pollution to environment, also causes certain injury to staff.Meanwhile, modified guar powder has strongly hydrophilic, and when entering in water, the part of fast hydrating easily wraps up the part not contacting water, is formed " flake ", hinders the release completely of viscosity.
Summary of the invention
Technical problem to be solved by this invention is to provide one and in use reduces dust injury, add again instant composition, make guar gum particle in water after rapid dispersion fast hydration rise sticky, namely avoid guar gum generation of " flake " in water, the easy dispersion making again the viscosity of guar gum discharge fast is without the preparation method of dust guar gum particle.
For solving the problems of the technologies described above, the invention provides the preparation method of a kind of easy dispersion without dust guar gum particle, it is characterized in that: described guar gum particle is with guar gum flour or modified guar powder for raw material, obtains through processes such as surface treatment, bonding, granulation, drying, screenings.
Further, the structure of described guar gum particle is spherulitic, ellipsoid is granular, oblate spheroid is granular, length is granular or side is granular.
Further, described guar gum particle is porosity and looseness particle, and described guar gum granular size is 1 ~ 5 millimeter.
Further, described guar gum particle surface process reagent used is tensio-active agent, soap, gelatin class, polyvinyl alcohol, Yelkin TTS etc., improve the dispersiveness of guar gum particle in water, the mass ratio of rubber powder and surface treatment agent is 100:0.5 ~ 2.0, and temperature of reaction is 45 ~ 65 DEG C.
Further, the reagent that the binder-treatment of described guar gum particle is used comprises water, alcohol-water mixture etc., and be preferably water, the mass ratio of rubber powder and binding agent is 100:20 ~ 40, and water temperature is normal temperature.
Further, the preparation method of described guar gum particle comprises stirring-granulating method, boiling granulation method, fluidization granulation method.
Further, the drying means of described guar gum particle comprises fluid-bed drying, boulton process, fluid-bed drying, air stream drying method.
Compared with prior art, beneficial effect of the present invention is:
The porous prilled guar gum that the present invention produces, in use reduce dust injury, add again instant composition, make guar gum particle in water after rapid dispersion fast hydration rise sticky, namely avoid guar gum generation of " flake " in water, make again the viscosity of guar gum discharge fast.
Accompanying drawing explanation
Fig. 1 is process flow sheet of the present invention.
Embodiment
