Abstract

The present invention provides an intelligent dosing device in oil field gas gathering and transportation station. A ball valve is connected to a filter; the other end of the ball valve is connected to a dosing outlet at the bottom of a solution tank; a metering pump is connected to a filter dosing outlet at the other end; a pressure gauge is connected to a buffer; the other end of the buffer is connected to the dosing outlet of the metering pump; a safety valve is installed in the dosing outlet of the metering pump and is connected with another metering pump inlet; a magnetic flip-type liquid level gauge is installed on the solution tank; a stirrer is mounted on the top of the solution tank; a check valve is connected between one metering pump and another metering pump; water inlets are distributed on the top of the solution tank; the magnetic pump is respectively connected to the solution tank and a dosing barrel; an overflow port and a drain outlet are located at the top and bottom of the solution tank; a platform and a chassis are connected to support the dosing device; and a check mouth and a steam inlet are located on the top of the solution tank. The device realizes real-time control of the dosing pump displacement based on the actual amount of incoming fluid and dosing concentration requirements. The device can achieve intelligent dosing.

Description

technical field [0001] The invention relates to the technical field of oilfield gathering and transportation in the petroleum industry, in particular to an intelligent dosing device in an oilfield gathering and transportation station. Background technique [0002] The chemical dosing in the gathering and transportation station of Changqing Oilfield is mainly based on the liquid inflow of the previous day, and the quantitative continuous dosing method is adopted. Due to the influence of objective factors such as production and construction, crude oil transportation, etc., the amount of liquid coming to the site is not stable, and the dosing cannot be adjusted in real time to ensure the dosing concentration, which affects the effects of crude oil demulsification and pipeline anti-scaling. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an intelligent dosing device in an oilfield gathering and transport...
