Abstract

The invention relates to a low-density high-strength ceramsite proppant prepared from flint clay as a raw material. In percentage by weight, a composition contains raw materials in content after the raw materials are mixed: 40-50% of Al2O3, 45-55% of SiO2, 0.5-3% of Fe2O3, 0.5-3% of TiO2, 0.1-2% of CaO+MgO, 0.1-1% of K2O+Na2O and the balance of ignition loss. According to the low-density high-strength ceramsite proppant prepared from flint clay as a raw material and the preparation method thereof, low-density high-strength ceramsites are prepared from the flint clay, so that the contradiction between the density and strength of the ceramsite proppant is solved, and the strength is relatively high while the density is low; the low-density high-strength ceramsite proppant has the advantages of low apparent density and bulk density, low broken rate, stable quality, high normal-temperature strength and low production energy consumption; the preparation method is simple, the material proportioning is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to a low-density and high-strength ceramsite proppant using burnt gemstones as raw materials and a preparation method thereof. Background technique [0002] During oil and gas deep well mining, high closure pressure and low permeability deposits are treated by fracturing to crack the oil-gas-bearing rock formations, and oil and gas are collected from the channels formed by the fractures. At this time, fluids need to be injected into the rock base to overcome formation fractures Intensive pressure creates cracks in the rock formations around the wellbore, forming a channel with high-level flow capability. In order to keep the cracks formed after fracturing open, oil and gas products can pass through smoothly. Petroleum proppant is used to enter the formation along with the high-pressure solution to fill in the fractures of the rock formation, which plays a role in supporting the fractures from closing due to stress release, so as t...
