Problems solved by technology

[0005] At present, due to the complex terrain during oil extraction, groundwater is easy to mix into the oil, so that the extracted oil contains a lot of water, which reduces the extraction efficiency. Therefore, there is an urgent need for a material that can reduce the water content inside the extraction well to improve oil production. mining efficiency

Abstract

The invention discloses a gel polymer material for reducing the water content of an oil well. The gel polymer material is prepared from fly ash, acrylic acid, bentonite, talcum powder, N-N methylene bisacrylamide, ethyl alcohol and methyl alcohol. The raw materials are common raw materials; the manufactured finished product material is poured into the mining well, and the material is used for adsorbing a water source in the mining well, so that the water content in the whole mining well is effectively reduced, the water content in the mined petroleum is reduced, and the petroleum mining efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of petroleum exploitation, in particular to a gel polymer material for reducing the water content of an oil well and a preparation method thereof. Background technique [0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons, which has a natural occurrence; petroleum is divided into crude oil, natural gas, natural gas liquid and natural tar, etc., but it is customary to use "petroleum" as the definition of "crude oil". . [0003] Petroleum is a viscous, dark brown liquid known as "industrial blood"; there are oil reserves in parts of the upper crust; the main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons; it is the main object of geological exploration one. [0004] The oil-forming mechanism of petroleum has two theories of biosedimentary oil and petrochemical oil. The former is more widely accepted. It is believed that oil is formed by organisms in anci...
