An online detection device for water content of crude oil with pressure protection function

Abstract

The invention relates to the technical field of on-line detection devices for the water content of crude oil, in particular to an on-line detection device for the water content of crude oil with a pressure protection function, which includes a casing, a liquid suction pump, a first liquid suction pipe, a first liquid outlet pipe, a first A one-way valve, an air bubble filter component and a water content detection component in crude oil, a liquid suction pump is installed on the casing, a first liquid suction pipe and a first liquid outlet pipe are arranged on the liquid suction pump, and a first one-way pipe is provided on the first liquid outlet pipe. The valve has an air bubble filter part installed on the shell, and the air bubble filter part communicates with the first liquid outlet pipe, and a crude oil water content detection part is arranged in the shell, and the crude oil water content detection part is respectively connected with the first liquid suction pipe and the air bubble filter part, and the air bubble filter part They are respectively electrically connected to the liquid suction pump and the water content detection component in crude oil. The invention filters the air bubbles in the crude oil, uses the water content detection part of the crude oil to complete the detection of the water content, and discharges the detected crude oil into the oil pipeline through the pump to complete the detection of the water content of the crude oil.

Description

technical field [0001] The invention relates to the technical field of an online detection device for the water content of crude oil, in particular to an online detection device for the water content of crude oil with a pressure protection function. Background technique [0002] In the process of crude oil extraction, the ratio of oil and water is an important parameter to characterize oilfield reservoirs, and it is also an important basis for formulating and adjusting oilfield production plans and optimizing production parameters. Is of great significance. [0003] At present, when testing the water content of crude oil, most of the online measurement methods are used to remotely detect the water content of crude oil. However, the extracted crude oil contains air bubbles, and the existing online measurement methods cannot remove the air bubbles in the crude oil. When the water content of crude oil is tested, it is easy to cause inaccurate detection results of the water con...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the shortcomings that the existing online measurement method cannot remove the bubbles in crude oil, which may easily cause inaccurate detection results of the water content of crude oil, and the online measurement method cannot follow the pressure change in crude oil, which may easily cause equipment damage. The technical problem is: to provide an online detection device for water content of crude oil with pressure protection function that is accurate in detection results and protects equipment following pressure changes
