Description

Technical Field

[0001] The utility model relates to the technical field of petroleum devices, in particular to a viscosity reducing agent filling device used in heavy oil wells. Background Art

[0002] Oil is generally mined and processed through oil wells and refineries. Oil wells are holes drilled by drilling methods. Generally, after the oil well reaches the oil layer, the oil layer casing is lowered, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas and water layers. Then, according to the requirements of oil field development, the oil layer is perforated with a perforating gun to form a channel, and the oil pipe is lowered. The oil is raised from the bottom of the oil well to the wellhead by using appropriate induction methods. The refinery refers to the process of distilling, catalyzing, cracking, pyrolysis, hydrofining and other processes of crude oil extracted from the formation to produce diesel and gasoline. Factories producing oil, kerosene, lubricating oil, petroleum coke, asphalt, ethylene and other products need to add viscosity reducers for processing when the concentration of oil is high. Viscosity reducers are organic polymers with inorganic affinity groups. A high-temperature viscosity reducer for drilling fluid has been developed abroad. It is an oilfield chemical added to drilling fluid. It consists of methylchlorosilane, modified water-soluble polyacrylonitrile, organic tin catalyst and fluoroalkylsiloxane. The base fluid is formed by heating and pressurizing reaction, and then humic acid is added. The reaction is carried out at 150℃~180℃ to obtain the silicon-fluorine high-temperature viscosity reducer for drilling fluid.

[0003] However, the existing viscosity reducer filling device used in heavy oil wells has a simple structure when in use, and cannot stir the raw materials of the viscosity reducer, thereby promoting the generation of the viscosity reducer in the device, and then reducing the filling efficiency of the viscosity reducer.
