Intelligent skid-mounted chemical dosing device used for oil field producing well sets

Abstract

The invention discloses an intelligent skid-mounted chemical dosing device used for oil field producing well sets. The device includes a chemical dosing pump arranged on an oil well, a chemical dosingmain pipe connected to the chemical dosing pump, and chemical dispensing pipes communicating with the chemical dosing main pipe; a pressure transducer and an automatic flow controller are installed on the chemical dosing main pipe; and a closed loop can be formed by the pressure transducer and the automatic flow controller. The device adopts an advanced automatic control technology, and forms theclosed loop with a pressure transmitter, so that automatic adjusting can be achieved, the constant pressure of the inlets and outlets of pumps and pipelines can be guaranteed, and quantitative functions can be accomplished; the compact structure and small land occupation area of the whole device can be realized through a reasonable and optimized pipeline process; through the utilization of computer technologies, control technologies and communication technologies, remote monitoring, sub-metering and data processing can be accomplished, and therefore, the device is suitable for current industrial modernization models, the enhancement of production management levels can be promoted, and refined management can be realized; and the device has an automatic remote-control function and a manualcontrol mode, so that the device is the best solution for paraffin and scale control and chemical dosing in oil fields.

Description

technical field [0001] The invention belongs to the technical field of oil field well group dosing, wax and scale prevention, and relates to an intelligent skid-mounted dosing device for wax and scale prevention in oil wells, which mainly consists of an intelligent dosing unit; a pipeline process unit; a dosing pump, Proportional control unit and data control unit. Background technique [0002] With the continuous development of the current oilfield, the problem of wax and scale prevention in the wellbore of the oilfield is prominent, but due to the complex situation of the formation, the situation of each well is different, and the dosing is done manually according to the situation, the labor intensity is high, there are many unsafe factors, and the waste of medicines is serious, etc. For various reasons, some oil wells have been in poor production status for a long time, which has seriously affected the normal oil production of oil wells.
