Abstract
The utility model discloses a there is cable direct-reading pressure gauge. The pressure gauge comprises a pressure gauge (1) arranged underground, wherein the pressure gauge (1) is connected with a decoder (3) arranged on the underground through a transmission cable (2), and the decoder (3) is connected with a computer (5) through a communication circuit (4). Compared with the prior art, the utility model discloses owing to adopted underground pressure gauge and the aboveground computer lug connection, can be with the real-time transmission of the pressure situation in the pit to aboveground, by the aboveground computer direct reading pressure in the pit. The safety of the oil well can be ensured, the production cannot be delayed due to instrument failure, and the oil production of the oil well is improved. The utility model discloses still have the structure succinct, convenient operation, safe, reliable characteristics. The pressure gauge can be placed underground for a long time, and data transmission is accurate without error codes.
Description
Technical field
The utility model relates to a kind of cable direct-reading pressure gauge that has, and belongs to the downhole data monitoring technical field.
Background technology
In the production of crude oil, in order to guarantee the safety of oil well and production, need monitor the pressure under the oil well, what adopt at present is the memory-type monitoring mode, specific practice is that a memory-type pressure meter is placed on the down-hole, the memory-type pressure meter detects the pressure of down-hole, and be stored in the pressure gauge, after detection in a few days, again pressure gauge is put on from the down-hole, the data that are stored in the pressure gauge are carried out playback, analyze the pressure Changing Pattern of down-hole, this detection mode, can not accomplish the pressure of down-hole is carried out real-time monitoring, if pressure gauge breaks down in the down-hole, aboveground monitoring personnel also can't know, directly influence the production of oil well, also have some unsafe factors in addition.Use very inconvenient.
The utility model content
The purpose of this utility model is, a kind of cable direct-reading pressure gauge that has easy to use is provided, it can with the pressure condition of down-hole real-time be passed to abovegroundly, directly read the pressure of down-hole by aboveground computer.Can improve the oil production of oil well, guarantee the safety of oil well.To overcome the deficiencies in the prior art.
The technical solution of the utility model: a kind of have a cable direct-reading pressure gauge, comprises the pressure gauge that is located at the down-hole, pressure gauge through transmission cable be located at aboveground decoder and be connected, decoder is connected with computer through communicating circuit.
Above-mentioned has in the cable direct-reading pressure gauge, and described pressure gauge is made up of the pressure gauge main frame, counterweight and the guide head that connect successively, and acquisition elements and coding circuit are installed in the pressure gauge main frame.
Aforesaid have in the cable direct-reading pressure gauge, and described transmission cable adopts armored cable.
Compared with prior art, the utility model since the pressure gauge that has adopted the down-hole directly be connected with aboveground computer, can with the pressure condition of down-hole real-time be passed to abovegroundly, directly read the pressure of down-hole by aboveground computer.Can guarantee the safety of oil well, can not delay production, improve the oil production of oil well because of instrument failure.The utility model also has simple for structure, and is easy to operate, safe and reliable characteristics.Pressure gauge can be put in the down-hole for a long time, and transfer of data is accurate, no error code.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the manometric pressure gauge main frame of a utility model partial enlarged drawing;
Fig. 3 is the partial enlarged drawing of manometric counterweight of the utility model and guide head.
Being labeled as in the accompanying drawing: 1-pressure gauge, 2-transmission cable, 3-decoder, 4-communicating circuit, 5-computer, 6-pressure gauge main frame, 7-counterweight, 8-guide head, 9-acquisition elements, 10-coding circuit.
The specific embodiment
Embodiment of the present utility model is as shown in Figure 1: it comprises the pressure gauge 1 that is located at the down-hole, pressure gauge 1 through transmission cable 2 be located at aboveground decoder 3 and be connected, decoder 3 is connected with computer 5 through communicating circuit 4.Described pressure gauge 1 is made up of the pressure gauge main frame 6, counterweight 7 and the guide head 8 that connect successively, as shown in Figure 2.Fig. 2 is a pressure gauge main frame partial enlarged drawing; Fig. 3 is the partial enlarged drawing of counterweight and guide head.Acquisition elements 9 and coding circuit 10 are installed in the pressure gauge main frame 6.In order to improve the intensity of transmission cable, described transmission cable 2 adopts armored cable.
Use-case of the present utility model: in the time need detecting to the pressure under the oil well, the pressure gauge that is connected with transmission cable from well head slowly put into oil well, pressure gauge is connected with transmission cable, because manometric front end is provided with smooth guide head and counterweight, slowly put transmission cable, pressure gauge relies on the weight of self to be placed into the down-hole.Then transmission cable is connected with aboveground decoder, decoder is connected with computer by communication cable, and the pressure to the down-hole that just can be real-time from the computer is monitored, and also monitored data can be printed, and uses for analysis and research.
The utility model not only can be used for oil well pressure and detect, and also can be used for the occasion of other remote inconvenient on-the-spot detected pressures.
