Abstract

The invention discloses an excitation enhancer for preparing an oil field fracturing propping agent, the oil field fracturing propping agent containing the excitation enhancer and employing deoiling waste residues as raw materials, and a preparation method of the oil field fracturing propping agent. The excitation enhancer comprises the following components, by mass: 5-10% of polydimethyldiallylammonium chloride, 3-5% of a polyaluminium chloride aqueous solution with a concentration of 6 wt%, 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 carboxymethyl cellulose sodium, 5-15% of sodium metasilicate, 10-15% of ethylene oxide, 1-3% of dioxane, 0.5%-1.0% of 8-hydroxyquinoline, 10%-15% of EDTA, and 5%-15% of cellulose ether; wherein the molecular weight of the poly dimethyl diallyl ammonium chloride is not higher than 30,000.

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 oil removal waste residue and a preparation method thereof, belonging to the technical field of oilfield environmental protection. Background technique [0002] Domestic refineries produce a large amount of oily sludge, which belongs to the list of hazardous waste. The waste residue after degreasing also belongs to the category of hazardous waste and needs to be treated and disposed of in an environmentally friendly and harmless manner. [0003] 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 scr...
