Abstract
The invention discloses a preparation method of a self-suspension proppant. The self-suspension proppant is prepared by dispersing a water-soluble polymer material into an aggregate at 15-150 DEG C, wherein the water-soluble polymer material is selected from natural polymer materials, artificially synthesized polymer materials or semi-naturally semi-artificially synthesized polymer materials, and the use amount of the water-soluble polymer material accounts for 0.1-15wt% of that of the aggregate. By virtue of optimized selection of raw materials and process conditions, a preparation process of the proppant which covers the polymer material simply, conveniently and effectively is dramatically obtained, the material cost is reduced, and a used covering material cannot cause pollution to the environment. The self-suspension fracturing proppant disclosed by the invention does not need high-cost fracturing fluid containing organic high polymers to perform fracturing, but directly uses natural water available everywhere to perform fracturing, so that pollution is reduced, and the cost is reduced.
