Problems solved by technology

Sintered bauxite and smelted zirconia ceramsite proppants have high strength, good chemical stability, and superior cost performance have been widely used in more and more oil fields, but their high density is easy to cause damage to fracturing equipment, especially aluminum Bauxite is a relatively precious mineral resource in the country. At present, the mining volume of high-grade bauxite mines in each province is only 1 million tons per year

Abstract

The invention discloses an excitation enhancer for preparation of oilfield fracturing proppants, an oilfield fracturing proppant containing the excitation enhancer and made from oilfield drilling solid waste, and a preparation method of the oilfield fracturing proppant. The excitation enhancer is made from, by mass, 5-10% of poly(dimethyl diallyl ammonium chloride), 3-5% of polyaluminum chloride solution having the weight concentration of 6%, 0.1-0.2% of polyoxyethylene lauryl ether, 2-5% of hydrogen peroxide, 4-8% of sodium aluminate, 20-30% of calcium oxide, 5-10% of sodium carboxymethyl cellulose, 5-15% of sodium metasilicate, 10-15% of ethylene oxide, 1-3% of dioxane, 0.5-1.0% of 8-hydroxyquinoline, 10-15% of ethylenediamine tetraacetic acid, and 5-15% of cellulose ether, wherein the molecular weight of poly(dimethyl diallyl ammonium chloride) is not higher than 30000.

Description

technical field [0001] The invention relates to an oilfield fracturing proppant and a preparation method thereof, in particular to an oilfield fracturing proppant containing oilfield drilling solid waste and a preparation method thereof, belonging to the technical field of oilfield environmental protection. Background technique [0002] During the drilling process of domestic oil and gas fields, oil-based drilling fluid is used to lubricate the drill bit, protect the well wall, and carry solid particles and powders such as drilling cuttings to the ground. The drill cuttings and other formation substances carried out of the mud are separated from the mud by solid control equipment (vibrating screen, desander, desilter, centrifuge and other equipment). The separated drilling cuttings and the mixture of waste mud, drilling additives, petroleum, high molecular organic matter, water and salt are called drilling solid waste. For every oil and gas well drilled in China, the total ...
