Abstract

The invention belongs to the technical field of paraffin removal balls for oil pipelines of oil production plants, and particularly relates to a corrosion inhibition paraffin removal ball for an oil pipeline of an oil production plant and a matched mold and manufacturing method thereof. The corrosion inhibition paraffin removal ball is composed of the following components in percentage by mass: 20-40% of a crude oil pour point depressant, 20-40% of a corrosion inhibitor, 10-20% of a binder, 0.1-6% of a disintegrating agent and 1-15% of a density regulator. The corrosion inhibition paraffin removal ball not only can be used as a paraffin removal ball, but also can run in a pipeline like an oil-resistant rubber ball, but also can be slowly dissolved in crude oil in the running process, the condensation point of the crude oil can be remarkably reduced after the paraffin removal component is dissolved, the paraffin precipitation rate of the crude oil is greatly reduced, and meanwhile, the viscosity of crude oil and the flow resistance are reduced; after the corrosion inhibition component is dissolved, the pipeline can be protected, and the pipeline is prevented from being corroded.

Description

technical field [0001] The invention belongs to the technical field of wax-removing balls for oil pipelines in oil production plants, and in particular relates to a corrosion-inhibiting wax-removing ball for oil pipelines in oil production plants, a matching mold and a manufacturing method thereof. Background technique [0002] Wax removal ball is a kind of pipeline dredging tool commonly used in the process of oil production in oil fields. It is usually made of oil-resistant rubber and has a diameter of 30-40mm. When in use, it is directly put into the pipeline. The wax on the pipe wall is pushed forward together until it is discharged out of the pipe, thus preventing the blockage of the pipe by wax deposition of crude oil. However, statistics from oil production plants in oilfields show that the recovery rate of general wax removal balls is only about 60%, and nearly 40% of wax removal balls have not been recovered, and most of them are due to being stuck in the pipeline. ...
