Abstract

The invention provides a petroleum proppant and a preparation method thereof. The petroleum proppant mainly comprises the following raw materials in percentage by weight: 75%-82% of ferro-nickel slag and 18%-25% of soft clay, wherein the sum of the percentages by weight of the raw materials is 100%. The preparation method of the petroleum proppant comprises the following steps: preparing raw materials, mixing the raw materials, prilling, firing and sieving. The petroleum proppant has the characteristics of low density, high-temperature resistance, high-pressure resistance, corrosion resistance, high strength, high flow conduction capability, low crushing rate and high thermal shock resistance; the petroleum proppant is used for reusing the industrial waste slag; the utilization rate of the resources is increased; the problem of the environmental pollution is alleviated; and in addition, the preparation method of the petroleum proppant is low in energy consumption, high in productivity and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a petroleum proppant and a preparation method thereof. Background technique [0002] Fracturing technology plays a very important role in oil extraction all over the world, and oil fracturing proppant is the key to the success of oil fracturing technology. High-quality proppant can play an important role in the extraction of crude oil. effect. Petroleum fracturing proppant is a support that keeps rock fractures deep in the formation open. The particle size can be selected, and it has a certain degree of roundness and sphericity. During use, the proppant is mixed into the fracturing fluid, and injected into deep rock fractures by high-pressure means to support the rock formation, so as to improve oil conductivity and increase crude oil production. [0003] Petroleum fracturing proppants are necessary special materials in fracturing operations in oil and gas fields...
