Description
Technical field
The utility model relates to exploration of oil and gas field and development field, is the well head pressure temperature measuring set of monitoring oil gas well well head pressure and variations in temperature.
Background technology
In oil and gas exploration and development process, recording occurring continuously well head pressure and temperature data are very important, the one, ask in the product process in test, need regularly and continuously write down well head pressure (being that oil jacket is pressed) and temperature data, the required recording frequency of initial stage is higher; The 2nd, in discharge opeing and pumping process,, also need recording occurring continuously well head pressure and temperature in order to monitor the discharge opeing situation.The well head pressure of domestic most of oil gas wells still adopts hand-kept at present.The shortcoming of this method is: 1. manual record, error rate height; 2. mechanical type well head pressure meter accuracy is low; 3. can not be automatically and recording occurring continuously; 4. pressure data can only be write down, and temperature data can not be write down.
Summary of the invention
The purpose of this utility model provides a kind of record and storage well mouth pressure temperature measuring set continuously, fast and automatically and accurately.
The purpose of this utility model is to realize like this, the well head pressure temperature measuring set, it is characterized in that: comprise pressure sensor, temperature pick up, analog-digital converter, single-chip microcomputer, flash chip and SD memory device at least, pressure sensor and temperature pick up are electrically connected with the analog-digital converter input port respectively, the delivery outlet of analog-digital converter is electrically connected with single-chip microcomputer, and display, flash chip and SD memory device are electrically connected with the control line data wire of single-chip microcomputer respectively.
Described single-chip microcomputer is electrically connected with RS232 interface circuit 8, and the RS232 interface circuit is electrically connected with computer.
The advantage of utility model is: the instrument that writes down oil gas field well head pressure and temperature data by the electronics mode, avoided the error of naked eyes meter readings, the accuracy of data record improves, the accuracy of instrument of mechanical pressure gauge is generally 1.5%, and after adopting this measuring instrument, pressure precision is brought up to more than 0.05% at least, has eliminated human error, otherwise address former machinery instrument can not write down automatically continuously, drawback that can't reading temperature data.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is the utility model embodiment circuit block diagram.
Among the figure: 1, pressure sensor; 2, temperature pick up; 3, analog-digital converter; 4, single-chip microcomputer; 5, display; 6, flash chip; 7, memory device; 8, RS232 interface; 9, computer.
