Abstract
The utility model relates to a detecting instrument for monitoring downhole pressure and temperature of oil and gas wells, in particular to a permanent pressure thermometer capable of transmitting pressure and temperature to a ground receiving apparatus to realize downhole pressure and temperature real-time monitor with cables. The pressure thermometer comprises a barrel body, a temperature and pressure sensor, a program control panel and a communication cable. The front end of the cylinder body is provided with a presser transmitting hole connector, the temperature and pressure sensor and the program control panel are connected with each other through circuits and then are arranged inside the cylinder body, the front end of the temperature and pressure sensor is connected with the presser transmitting hole connector, the program control panel is connected with the communication cable, the back end of the cylinder body is equipped with a cable sealing device, and the communication cable extends out of the cylinder body through the cable sealing device. Downhole pressure and temperature signals are directly converted into digital signals which then are transmitted to a ground control instrument through the program control panel, then the ground control instrument transmits real-time values to a computer, and finally ground staff can obtain downhole pressure and temperature directly from the computer, which is very convenient.
Description
Technical field
The utility model is a kind of detecting instrument of monitoring oil gas well down-hole pressure and temperature, and particularly a kind of cable that adopts passes to the permanent type pressure thermometer that the ground receiving device realizes that the bottom pressure temperature is monitored in real time with pressure and temperature.
Background technology
Existing capillary tube permanent pressure meter mainly is that the mode of utilizing capillary tube ground to annotate nitrogen is obtained formation data, and it can only the transmission pressure value, no temperature demonstration; And obtain data at every turn and need repeat to cover nitrogen, process complexity, cost cost height.
Summary of the invention
The purpose of this utility model is not have in order to overcome existing capillary tube permanent pressure meter that temperature shows and the defective of process complexity, invent a kind ofly by cable pressure and temperature to be passed to the permanent type pressure thermometer that the ground receiving device realizes that the bottom pressure temperature is monitored in real time.
The purpose of this utility model realizes as follows: described permanent type pressure thermometer, comprise cylindrical shell, pressure-temperature sensor, program board and communication cable, the front end of cylindrical shell is provided with the pressure transmission hole joint, pressure-temperature sensor be located in the cylindrical shell after program board is connected by circuit, the front end of pressure-temperature sensor is connected with the pressure transmission hole joint, program board is connected with communication cable, the end of cylindrical shell is provided with cable sealing device, and communication cable stretches out in outside the cylindrical shell by cable sealing device.
Described cable sealing device is made up of cable seal urceolus, cable fixed cover, cable packing, cable lock tube, and cable fixed cover and cable packing are located in the cable seal urceolus, is provided with the cable lock tube between cable fixed cover and the cable packing.
Described cylindrical shell adopts the nichrome material.
Described pressure-temperature sensor is made up of silicon jewel chip.
Good effect of the present utility model is as follows: because the pressure and temperature of down-hole is directly by program board pressure, temperature signal to be converted to data signal to pass to the Ground Control instrument, the Ground Control instrument is transferred to real-time numerical value in the computer again, so the ground handling personnel directly just can obtain the pressure and temperature of down-hole in the computer, and are very convenient; In addition, but resistance to compression when cable sealing device is connected communication cable outside, anti-sealing, anticorrosive, and can connect communication cable fast; Cylindrical shell adopts the nichrome material, and anti-hydrogen sulfide, carbon dioxide guarantee to use in oil-water well for a long time.
