Five, embodiment:
As seen from the figure, the data acquisition process instrument mainly is by monolithic processor controlled LCD MODULE 6, RS232 Serial Port Line 11, clock module and data-storing and signal processing in the surface-mounted integrated circuit 19.Sensor section is made of liquid level sensor 2 and the ultrasonic liquid leveller 13 that is installed in the magnetic inversion liquid level gauge 1 of a side and is installed in separation vessel 10 tops, and be connected with separation vessel 10, vent valve 17 is installed above separation vessel 10, feed tube 7 is installed below separation vessel 10, and associated line 18 of the present invention is equipped with in the top; The control that is connected with thin film switch 5 of LCD MODULE 6 in the single-chip microcomputer in surface-mounted integrated circuit 19, one side links to each other with liquid level sensor 2, magnetic inversion liquid level gauge 1 by signal communication interface 4, signal wire 3, another path ultrasound wave control line 16 is connected with ultrasonic liquid leveller 13, and one road electric signal communication interface 4 is connected with microcomputer 12 through RS232 Serial Port Line 11 again.
Its course of work is like this:
By dry-reed position transducer 2 is installed in original magnetic inversion liquid level gauge side, metering plant separation vessel 10 places, ultrasonic liquid leveller 13 is installed at separation vessel 10 tops, liquid level sensor 2 liquid level signals send moisture measurement mechanism to by communication interface 2, when liquid level reaches liquid level gauge and presets peak, the liquid level data that this device is obtained in separation vessel this moment by ultrasonic liquid leveller 13 by ultrasonic communication control line 16, when liquid level reaches liquid level gauge and presets minimum point, the liquid level data that this device is obtained in separation vessel this moment by ultrasonic liquid leveller 13 by ultrasonic communication control line 16 once more, utilize moisture influence in the liquid measure for liquid measure density, it is poor with the interior liquid level of corresponding separation vessel finally to be reflected in liquid level gauge preset height difference, thereby obtains water percentage; The single-chip microcomputer of this device is handled, is stored data as the core of data processing, utilizes Liquid Crystal Module to show, by communication signal interface and microcomputer communication, carries out data readback, realizes the robotization of oilfield moisture measurement.
Its application characteristic is:
1, measure accurately: compare with traditional water gaging that contains, adopt this device to measure, container is to separate Device is compared with the sampling oil drum, and volume is big, and the data that record are accurate, objective, and save the work on the spot people The member carries the trouble of sampling oil drum field sampling every day.
2, Real-time Collection: this instrument band clock control circuit, can automatically record the time of measuring various data, Accuracy is accurate to second. When measuring water ratio in oil well, gather individual well production fluid amount and automatically gather this well The temperature of metering room and Measuring Time have guaranteed the uniformity of four measurement indexes, stopped the staff because of Error and cause measuring pound sign and actual pound sign is inconsistent. Measurement data is by this instrument and squad's computer communication, Microcomputer is differentiated its accuracy by contrast and the processing of every data, automatically makes production report, thereby protects Demonstrate,prove the true and reliable of every data.
3, simple to operate: this device instrument has two row, ten Chinese character LCD MODULE to show, actions menu adopts full Chinese prompt, only just can finish various function choosing-items with 5 simple key-press, and operation indicating arranged, the operation indicating oil field actual conditions of combining closely, the staff who is familiar with on-the-spot gauging only need simply train the technical ability that just can on top of use this instrument.Use this instrument, not only do not increase field personnel's workload, and removed the work that field personnel and the documenter of production crew calculate, copy form from.
4, easy to carry: this installs main instrument is the portable intelligent instrument, and the field personnel of production crew needs take back squad with oneself every day, prevents that the lawless person from stealing.
5, unique system powers: this device is low-power consumption, and working current is direct current 5V.Both can adopt external transformer 12V power supply, also can adopt the internal battery power supply.Battery adopts the memoryless property of high-power rechargeable battery, and battery can be operated in rapid charge and trickle charge state, and two states can automatically switch.The staff can take back squad with instrument and charge, and need not to look after, and quickly charging battery can be full of after 4 hours, and cut the trickle charge state automatically and can charge for a long time, but continuous working more than 5 hours after battery is full of.
6, automatic recognition system: because of the pound sign of each test satellite location different with the separation vessel model, need and be solidificated in the instrument at the independent making software of the employed instrument of each test satellite location, system discerns this instrument automatically and belongs to which test satellite location when data readback, stopped the problem of the data readback confusion that maloperation causes, so this instrument can not be general between test satellite location.
7, install simply: do not change the flow process of former test satellite location when this instrument is installed, do not influence the ordinary production of oil well, only need on the basis of original test satellite location flow process, to install the sensor of this instrument of cover.
