Problems solved by technology

During the process of pipeline transportation of crude oil, these waxes will crystallize out due to cooling, seriously affecting the normal transportation of crude oil
If a station-by-station heating process is used to raise the temperature and reduce the viscosity of crude oil, the fuel power consumption accounts for about 30% of the oil transportation cost, and at the same time, light oil in crude oil will be lost

Abstract

The invention provides a drag reducer with a pour-point depression function and a preparation method of the drag reducer. The drag reducer comprises components in parts by weight as follows: 147-150 parts of 1-butylene hydrocarbon, 180-185 parts of vinyl acetate, 0.5-1 part of titanium tetrachloride-triethylaluminium, 570-575 parts of n-butyl alcohol and 90-100 parts of an emulsifier OP. According to the drag reducer with the pour-point depression function, the condensation point of crude oil can be effectively reduced, the energy loss in the crude oil flowing process is reduced, energy consumption can be greatly reduced, the pour point of the crude oil is reduced by 10 DEG C, the drag reduction rate is increased by 47.6%, the throughput increase rate is increased by 43.7%, the throughput can be improved, the flow speed is increased, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a foaming agent for gas well development in the field of oil and gas fields, in particular to a pour-point and drag-reducing agent and a preparation method thereof. Background technique [0002] Drag reducer is a chemical agent that reduces fluid flow resistance, which is of great significance to energy saving and consumption reduction in the process of fluid pipeline transportation and to increase pipeline transportation volume. [0003] The frictional resistance of the fluid restricts the flow of the fluid in the pipeline, resulting in reduced pipeline throughput and increased energy consumption. The development trend of pipeline transportation of high-waxy, high-viscosity and condensable crude oil technology is to gradually reduce the oil transportation temperature, and then realize normal temperature transportation. At present, all countries in the world, especially the big countries that are rich in waxy and viscous crude...
