Abstract

The invention discloses an additive for a fracturing propping agent, the fracturing propping agent and a preparation method, belonging to the technical field of oil field chemical industry. The additive for the fracturing propping agent comprises the following components by weight: 15.5 to 18% of boric acid, 65 to 70% of attaclay and 12.5 to 18% of silica fume. The fracturing propping agent comprises the following components by weight: 52 to 82% of low-grade bauxitic clay, 5 to 15% of calcined kaolin, 10 to 25% of waste produced fracturing propping agents and 3 to 8% of the additive for the fracturing propping agent. The additive for the fracturing propping agent prepared in the invention has low cost; the prepared fracturing propping agent has the advantages of low volume density, low apparent density, low acid solubility, a low broken rate, etc., enables production cost and fracturing cost to be reduced and is favorable for yield increase of oil and gas fields. According to the invention, the waste produced fracturing propping agents are added as a raw material, so cyclic utilization of a waste material is realized.

Description

technical field [0001] The invention specifically relates to an additive for a fracturing proppant, a fracturing proppant using the additive and a preparation method thereof, and belongs to the technical field of oilfield chemicals. Background technique [0002] The purpose of the fracturing proppant is to split the oil-gas-bearing rock strata after the high closure pressure and low permeability deposits are fractured when the oil and gas wells are exploited, and the oil and gas are collected from the channels formed by the cracks. The ceramsite proppant material is used together with the high-pressure solution to enter the formation and fill in the rock fractures to support the cracks from closing due to stress release, thereby maintaining high conductivity, allowing oil and gas to flow smoothly, and increasing production. Ceramsite proppant is widely used in the exploitation of oil and gas to increase oil and gas production and support the ground from subsidence. [0003]...
