Abstract

The invention relates to a medium density propping agent used in waste ceramsite recycling production and a preparation method thereof. The medium density propping agent is prepared from the following raw materials in percent by weight: 80-90% of bauxite, 5-15% of waste ceramsite powder and 5-10% of fluxing agent. According to the medium density propping agent and the preparation method thereof which are disclosed by the invention, waste ceramsite produced in a production process is recycled, resource is saved, environmental pollution is reduced, product cost is reduced, and a product produced by adopting the preparation method disclosed by the invention completely meets the national quality standard. Meanwhile, lithium hydrate or a mixture of lithium hydrate and manganese powder is adopted as the fluxing agent besides the manganese powder, and the ceramsite propping agent prepared by adopting the lithium hydrate as the fluxing agent is lower in breaking rate. The lithium hydrate has single chemical components, so that fluctuation of quality of the ceramsite propping agent can not be caused owning to unstable chemical components of the fluxing agent.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic ceramic materials, and in particular relates to a medium-density proppant produced by recycling waste ceramsite and a preparation method thereof. Background technique [0002] Petroleum fracturing proppant (ceramsite sand) is a kind of ceramic particle product with high fracturing strength. It is mainly used for downhole support in oil and gas fields to increase oil and gas production. It is an environmentally friendly product. This product is a substitute for medium and low-strength proppants such as natural quartz sand, glass balls, and metal balls, and has a good effect on increasing oil and gas production. [0003] 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 gather from the channels formed by the fractures. Petroleum fracturing proppant is used along with t...
