A dynamic experimental device for electrocoalescence dehydration

Abstract

The utility model relates to an electric coalescence dehydration dynamic experiment device, which belongs to the field of dehydration dynamic experiment equipment. It is characterized in that: the outlet end of the oil-water emulsion preparation device is respectively connected to the inlet of the dynamic electric coalescer (8) and the observation port, and an image acquisition and processing device (4) is arranged on the side of the observation port; the dynamic electric coalescer (8) One side is provided with a plurality of sampling ports (7), and the plurality of sampling ports (7) are respectively connected to observation ports. The present invention can sample at any end position of the dynamic electric coalescer according to the needs of the experiment, and optimize the diversification of sampling as much as possible. The inlet and observation port of the coalescer can respectively collect the image of the sample directly output from the oil product after the oil-water preparation, and the image collection of the oil product mixture after the action of the electric field and the serpentine circulation through the image acquisition and processing device. It can facilitate the comparison of experimental data and improve the accuracy of experimental research.

Description

technical field [0001] The utility model relates to an electric coalescence dehydration dynamic experiment device, which belongs to the field of dehydration dynamic experiment equipment. Background technique [0002] Petroleum is a precious non-renewable strategic resource. With the development of society, the consumption and demand of petroleum are increasing day by day. Most of my country's oil fields have entered the middle and late stages of oil production, and the difficulty of extracting oil from the formation has greatly increased. The tertiary oil recovery methods such as chemical flooding and composite flooding are usually adopted, and the recovered crude oil has a high water content (the water content in the oil produced in some oilfields is as high as 90%) and usually exists in the form of a very stable oil-water emulsion. Water content in crude oil not only increases energy consumption during storage and transportation, but also causes negative problems such as ...

AI Technical Summary

Problems solved by technology

The survey found that researchers have done more research on static electric coalescence dehydration, but relatively less research on dynamic electric coalescence dehydration; the existing dynamic electric coalescence dehydration experimental devices are generally large in size, and it is difficult to achieve isokinetic sampling; Some devices change the electric field time while changing the flow rate, so the influence of flow state and electric field time on the efficiency of electrocoalescence dehydration cannot be analyzed by single factor
