Description

Crude oil free water measuring instrument

Technical Field

The application belongs to crude oil free water measurement field, concretely relates to crude oil free water measuring apparatu.

Background

The tertiary oil recovery polymer flooding technology has the defect of high content of impurities such as polymers, sulfides and the like in produced liquid media, so that the problems of unbalance electric dehydration control and overproof oil content in water caused by inaccurate detection of a free water interface appear in a combined station gathering and transportation process system. Therefore, the accuracy of interface measurement and control affects the water content of the purified oil, the oil content index of the sewage and the stability of the process and equipment working system. At present, the detection of the liquid level of the free water remover in most of oil field united stations has the problems of inaccurate measurement and difficult cleaning.

Detailed Description

The following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application.

The utility model provides a crude oil free water measuring apparatu, includes shell 1 and sensor 4, be equipped with solvent chamber 5 in the shell 1, sensor 4 (measuring the free water in the heavy oil) is located solvent chamber 5 to wear the cover on stop device 3, stop device 3 passes through lead screw 2 and is connected with motor 7, motor 7 is fixed on shell top cap 8, be equipped with ultrasonic transducer 6 on the bottom of shell 1. Two ends of the limiting device 3 are fixed on the inner wall of the solvent cavity 5, and the limiting device plays a role in limiting and supporting the downward movement distance of the motor. The solvent chamber 5 is filled with crude oil detergent.

The sensor is characterized in that a sensor moving hole is formed in the bottom of the shell, a sealing rubber ring 10 is arranged in the sensor moving hole, and a probe of the sensor is located in the sealing rubber ring 10. And a tape connecting port 9 is arranged on the upper end surface of the shell top cover 8. Bottom feet 11 are arranged on the lower end face of the shell top cover 8, and the number of the sensors 4 is two and the two sensors are respectively located at two ends of the limiting device 3.

Principle of operation

The button passes through single chip microcomputer control whole detecting system, triggers a button, and then motor 7 drive lead screw 2 rotates, and lead screw 2 moves the in-process upwards, and two sensors 4 retrieve the solvent intracavity from sealing rubber circle 10, and the bottom of until sensor and solvent chamber 1 bottom are on same water flat line. At the moment, the ultrasonic transducer 6 utilizes the cavitation action, the acceleration action and the direct current action of ultrasonic waves in a solvent to directly and indirectly act on sticky heavy oil on the sensor, so that a sticky layer is dispersed, emulsified and stripped to achieve the purpose of cleaning the sensor (the ultrasonic generation time is set to be 15 seconds), the friction between the sealing rubber ring and the sensor can also play a certain cleaning role when the sealing rubber ring and the sensor are recovered, after the cleaning action is finished, the motor 7 drives the screw rod 2 to rotate, and the sensor is placed outside a solvent cavity to perform free water detection work.

The sensors measure water by adopting the conductivity principle, and when the two sensors form a passage in a conductive medium, the control end sends out a dripping sound.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
