The specific embodiment
Referring to Fig. 1, a kind of oil well individual well automatic oil-measuring device, mainly by gauging chamber 6, Oil-gas Separation umbrella 3, magnetic flap level gauge 5, upper signal transducer for liquid level control 4, lower signal transducer for liquid level control 8, electric three passes ball valve 9, the compositions such as PLC control circuit 11, feed tube 22, flow line 7, natural gas line 2, oil and gas pipe line 10.
Oil-gas Separation umbrella 3 is umbrella and is positioned at gauging chamber 6 internal upper parts, has aperture to be evenly distributed on Oil-gas Separation umbrella 3; Upper signal transducer for liquid level control 4 is positioned at the bottom of the top Oil-gas Separation umbrella 3 in gauging chamber 6; Lower signal transducer for liquid level control 8 is positioned at the bottom in gauging chamber 6; Upper and lower signal transducer for liquid level control 4,8 respectively by valve 3. 17,4. valve 18 be connected with the upper and lower end that is positioned at the magnetic flap level gauge 5 of placing with gauging chamber 6 outer wall parallel vertical; Feed tube 22 inserts from the top in gauging chamber 6, and is positioned at the top of Oil-gas Separation umbrella 3; Flow line 7 inserts from the bottom in gauging chamber 6, and the other end is connected with electric three passes ball valve 9; Natural gas line 2 by valve 2. 16,1. valve 15 be connected with the top in gauging chamber 6, the other end is connected with electric three passes ball valve 9; Electric three passes ball valve 9 is connected with flow line 7, natural gas line 2, flow line 10 respectively; 2. 20 upper and lower signal transducer for liquid level control 4,8, electric three passes ball valve 9 be respectively by holding wire 1. 19, and holding wire, 3. holding wire 21 be connected with PLC control circuit 11.
Operating principle: the production fluid of oil well flows out from oil reservoir 29, enter successively sleeve pipe 18, oil pipe 27, by tubing valve 23, feed tube 22, be injected on the Oil-gas Separation umbrella 3 in gauging chamber 6, feed liquor launches on Oil-gas Separation umbrella 3, natural gas overflows in liquid, realize Oil-gas Separation, natural gas is positioned at the top in gauging chamber 6, and stratum production fluid is positioned at the bottom in gauging chamber 6, with landing surface production fluid inlet oil pocket 6, liquid level 25 constantly rises, gauging chamber 6 in the process of feed liquor, the natural gas on its top by valve 2. 16, valve 1. 15, natural gas line 2, electric three passes ball valve 9(its be the gauging chamber feed liquor exhaust condition of Fig. 3) enter oil and gas pipe line 10 until oil-gas gathering and transportation system, when liquid level 25 reaches upper signal transducer for liquid level control 4, 2. upper signal transducer for liquid level control 4 20 reaches PLC control circuit 11 by signal by holding wire, PLC control circuit 11 is passed to electric three passes ball valve 9 by the instruction of 12 90 ° of the ball valve cores of turning clockwise, electric three passes ball valve 9 moves according to instruction, this is the gauging chamber discharge opeing state that electric three passes ball valve 9 is Fig. 2, liquid in gauging chamber 6 is by flow line 7, electric three passes ball valve 9, oil and gas pipe line 10 drains into oil-gas gathering and transportation system, natural gas outlet on gauging chamber 6 is closed at electric three passes ball valve 9, natural gas is assembled and is expanded on the top in gauging chamber 6, compressing liquid level 25 declines, when liquid level 25 drops to lower signal transducer for liquid level control 8, 1. lower signal transducer for liquid level control 8 will 19 reach PLC control circuit 11 by signal by holding wire, PLC control circuit 11 is passed to electric three passes ball valve 9 by the instruction that is rotated counterclockwise 12 90 ° of ball valve cores, electric three passes ball valve 9 moves according to instruction, repeat the feed liquor exhaust process in gauging chamber.
The time that liquid level 25 changes between upper and lower signal transducer for liquid level control 4,8 is memorized by PLC control circuit 11, and the volume in the gauging chamber 6 between upper and lower signal transducer for liquid level control 4,8 is constants, obtains the instantaneous delivery of oil well by calculating.PLC control circuit is the oil well stratum production fluid amount of a day by recording the oil well liquid-producing of the inlet oil pocket 6 of 24 hours.Like this, by individual well automatic oil-measuring device, both instantaneous delivery can be obtained, also integrated flow can be obtained.
Magnetic flap level gauge 5 can intuitively reflect the variation of the liquid level 25 in gauging chamber 6, and the production fluid amount of energy human metering oil well is that a kind of of automatic metering function supplements.Casing valve 24 can regulate the casing pressure of oil well.
On PLC control circuit, data acquisition and transmitter unit can be set, gauging data be sent to LAN and for related personnel, browse.
When having a power failure, electric three passes ball valve is adjusted to Fig. 2 state automatically, opens oil flow channel.
The innovative design of this device throughput oil recess structure and with the combination of automatic control technology, realized oil well instantaneous, the completing of accumulative total automatic metering function; Can as a kind of of automatic gauge, supplement by human metering again simultaneously.Be a great change of outlying oil well one-well metering, there is very important economic benefit and social benefit.Electric three passes ball valve is an innovation.
