Abstract

The invention discloses a ceramsite proppant composition, a preparation method and application thereof. The ceramsite proppant composition consists of the following raw materials by weight: 35-45 parts of bauxite, 7-13 parts of silicon carbide, 16-24 parts of montmorillonite, 3-8 parts of titanium oxide, and 1-5 parts of cobalt oxide. The preparation method includes: crushing bauxite and silicon carbide, performing soaking with a cyclohexane solution, and conducting drying, then adding hydrogen peroxide and conducting stirring treatment to obtain mixed powder; mixing titanium oxide and cobalt oxide and performing crushing, putting the mixture and the mixed powder into a prepared montmorillonite solution simultaneously, conducting stirring, ultrasonic treatment, stirring to dry, granulation, and firing, thus obtaining the composition. The ceramsite proppant composition prepared by the method provided by the invention has the characteristics of high compressive strength, high apparent density, good sphericity, simple process, and low manufacturing cost, has high flow conductivity during use, is especially suitable for high flow conductivity fracture mining of shallow oil and gas wells, improves the reasonable utilization of resources, also a low firing temperature range is adopted, and the energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of oilfield fracturing materials, in particular to a ceramsite proppant composition, a preparation method and application thereof. Background technique [0002] Petroleum proppant is also called petroleum fracturing proppant. It is mainly used for downhole support in oil fields to increase oil and gas production, and is an environmentally friendly product. 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. ...
