Abstract
The utility model relates to a dual-path memory typed electric pressure gauge, in specific referring to a device which is used to test the dynamic pressure and temperature of the underground fluid in the petroleum exploration and exploitation field. The utility model comprises a seal socket sleeve provided with two sets of sensors and liquid inlet holes, a master seal bin provided with a circuit board, a battery seal bin and a tail cap etc. A temperature sensor and two identical sets of data collecting and processing systems are arranged on the circuit board to accomplish the recording and memorizing two groups of data simultaneously. A standard communication interface is arranged on the circuit board as well. Each part is in thread connection with each other and is provided with an O shaped rubber seal ring. The tail part is a tail cap which can thread and tie steel wires. The utility model has the advantages of a simple structure, integrating two instruments into one, a small volume, accurate pressure testing point, low cost in construction and convenience in operation.
Description
1. technical field the utility model relates to a kind of dual-path stored type electronic pressure gauge, is in the exploratory development such as oil specifically, is used to test the device of downhole fluid dynamic pressure and temperature.
2. the dynamic pressure and the temperature of oil-water-layer under the testing well often wanted in the background technology oil field in exploitation, existing multiple measuring method and device, and the ordinary electronic pressure gauge is exactly one of them.Because appliance requires continuous working in the high temperature and high pressure environment of down-hole in case instrument is found not obtain PRESSURE DATA or only obtained part information after mentioning ground, must be descended well measurements for a long time in accordance with regulations again.To get accurate pressure entirely and change data in order to get, the method that adopts two or three pressure gauges to be cascaded of having to, expectation can have a pressure gauge can measure success at least.But this will cause instrument excessive or long, and pressure tap is inaccurate, and construction cost and expense increase, and in the well, lose particularly evident in case instrument comes off.
3. summary of the invention the utility model designs a kind of dual-path stored type electronic pressure gauge, comprises the cover for seat that two sleeve pressure sensor and inlet opening are housed, and the primary seal storehouse of wiring board is housed, and cell sealing storehouse and tail cap etc.Wiring board is provided with two temperature sensors and the identical data acquisition processing system of two covers, and they are made up of amplifier, analog to digital converter, single-chip microcomputer, storer and clock system etc. respectively.Under the scm software programmed control, two cover electronic system automatic pressure acquisition and temperature signals after amplification and quantification treatment, are finished record synchronously and are stored two groups of data.Also be provided with the RS232 standard communication interface on the wiring board, to cooperate and microcomputer communication.Each several part is by being threaded, and is added with O type rubber seal, and afterbody is the tail cap of tying steel wire.
The utility model is simple in structure, and an instrument is worked as two to be made, and volume is small and exquisite, and pressure tap is accurate, and construction cost is low and easy to operate.
4. description of drawings Fig. 1 is the utility model structural profile synoptic diagram (comprising circuit block diagram).1-inlet opening 1 among the figure, 2-O type O-ring seal, 3-cover for seat 1,4-pressure transducer 1,5-inlet opening 2,6-cover for seat 2, the 7-cable-through hole, 8-pressure transducer 2,9-temperature sensor, 10-data acquisition process and storage system, 11-primary seal storehouse, 12-standard interface circuit, the 13-wiring board, 14-communication and power interface, 15-battery compartment, the 16-battery, 17-tail cap.
5. embodiment is pressed the oil well test routine operation, be connected with instrument tail cap (17) with the test steel wire for logging, sling instrument and it is fallen in the well behind the position to be measured, FIH by with the inlet opening 1,2 (1,5) of external communications, make the pressure transducer 1,2 (4,8) that is installed in respectively on the cover for seat 1,2 (3,6) detect the pressure of fluid, the machinery of sensor self is installed and is reached sealing effectiveness again simultaneously.Two pressure transducers are finished processing and storage with identical data acquisition process and the storage system (10) of two covers in the electric signal that two temperatures sensor (9) produces respectively is transferred to primary seal storehouse (11).The battery (16) that is contained in the battery compartment (15) is given circuit supply by communication and power interface (14).Communication and power interface (14), temperature sensor (9), data acquisition process and storage system (10) and standard interface circuit (12) are installed on the wiring board (13), and wiring board is fixed on the cover for seat 2 (6).By being threaded, and add O type O-ring seal (2) between cover for seat 1,2 and primary seal storehouse and the cell sealing storehouse.
After test was finished, instrument was mentioned ground, screwed off cell sealing storehouse (15), used the standard interface line that communication and power interface (14) are connected with microcomputer, finished transmission and playback process data information task.
Claims (3)
1, a kind of dual-path stored type electronic pressure gauge, form by gas-tight silo, sensor and wiring board etc., it is characterized in that being respectively equipped with on cover for seat 1 (3) and the cover for seat 2 (6) inlet opening 1 (1) and inlet opening 2 (5) with external communications, pressure transducer 1 (4) and the pressure transducer 2 (8) installed on it reach sealing effectiveness again; The identical data acquisition process of two covers and the wiring board (13) of storage system (10), temperature sensor (9), standard interface circuit (12) and communication and power interface (14) are housed to be fixed on the cover for seat 2 (6).
2, according to the described dual-path stored type electronic pressure gauge of claim 1, it is characterized in that cover for seat 1 (3) and cover for seat 2 (6), cover for seat 2 (6) and primary seal storehouse (11) all being threaded, and are added with O type O-ring seal (2) between the cell sealing storehouse (15) of primary seal storehouse (11) and tail cap (17).
