Abstract

The present invention relates to an oil medium sensing detection device in oil field production well wireless monitoring system. It is characterized by that it can increase a function for detecting oil content data of finished product in said oil field production well wireless monitoring system. Said invention provides a non-inserted capacitor oil medium sensor. Said invention utilizes a semi-circular card as capacitor grounding electrode, two capacitance measuring electrodes and a sensor external shell to form the invented non-inserted capacitor oil medium sensor.

Description

Technical field: [0001] The invention relates to an oil medium sensing and detecting device in a wireless monitoring system for an oil production well in an oil field. Background technique [0002] The wireless monitoring system of oil production wells in oil fields can be designed as a wireless network communication method to realize the communication transmission control between the central computer and each terminal unit. In order to realize multi-directional automatic system monitoring and control management, it is necessary to set up various types of sensors to collect and detect the operating status of the oil production well mechanism on the spot. Comprehensive understanding and mastery of oil production conditions, oil production process, oil field quality, and oil output quality. Existing medium detection sensors are all medium-intervention sensors, which have complex structures and need to change the oil pipeline, which brings great difficulties to repair and main...
