Description
Technical field
The utility model is related to a kind of oil field measurement apparatus, more particularly to a kind of metering device of oil well well yield.
Background technology
Petroleum metering work is big, the relatively complicated element task of a workload, and continuous data is mainly used in oil field life
The Production rate of product process, reserves control and production management etc., the accuracy of metering is directly connected to the reasonable strategy of enterprise
Deployment and economic benefit, therefore, perfect measuring system is established and improve, rationally strict carries out oil well measurement management, accurate in time
The sustainable development of true grasp oily well yield and fluctuation pattern to oil field is played an important role, and is also to ensure oil field production
Core.
The method for production metering of oil wells that each oil field domestic at present adopts mainly has glass tube oil gauge orifice plate to survey gas, tipping bucket gauging
Orifice plate surveys gas, two-phase laminated flow densimetry and three-phase separator measurement method etc..Measurement (1) the gauge glass amount of single-well crude oil
Oil installs one long 80 or so on gs-oil separator and the gauge glass of communicating pipe is constituted with separator.One in separator
The oil for determining weight falls hydraulic pressure in glass tube, is divided with the relation of oil mass in separator according to the height that water in glass tube rises
The weight of oil, thus measures the time required for liquid level lifting height in glass tube in device, you can the yield of conversion producing well.
Glass tube oil gauge is the conventional method that domestic each oil field generally adopts, and accounts for more than the 90% of oil well sum.The method equipment letter
Single, small investment, but due to converting yield by the way of interval gauging, cause crude system error to be 10%～20%.Separately
External high water-cut stage, particularly in ultra-high water cut stage, the discharge opeing after the oil well measurement low for gas liquid ratio is very difficult, the metering
Operation puts to no little inconvenience.(2) telegram gauging is on the basis of gauge glass gauging, on the gauging height H of regulation,
Under one electrode of each installation, when it is waterborne be raised to bottom electrode when, timing ammeter turns on beginning timing, waterborne when being raised to Top electrode, electricity
Table cut-out stopping is walked about, and is recorded water and is risen the high time t of H, then can calculate producing well according to the method for gauge glass gauging
Yield.(3) tipping bucket gauging tipping bucket oil-measuring apparatus are mainly made up of oil jug, counter etc..One bucket translates into row when filling
Oil, another bucket charge of oil, such iterative cycles carry out accumulation oil mass.
Existing method is suffered from the drawback that：
1. error in dipping is big.Because some oil wells Liquid output fluctuates greatly, and there is intermittency, the metering nothing of Liquid output
Method accomplishes 24 hours continuous meterings, and continuous data cannot ensure accuracy, and error in dipping is larger.
2. randomness is sampled.Because a large amount of oil developments are in the middle and later periods, produced water cut is more, online analyzer of water content knot
Really undesirable, manual sampling randomness is big, it is impossible to obtain accurate water cut value.
3. instrument failure.Stuck, the bridging phenomenon that detecting instrument occurs easily causes motor-driven valve misoperation, as a result inaccurately,
It is difficult to control to the oil pressure of separator.
CN205400711U discloses a kind of optical fiber type single well metering device, including tank body, is provided with the tank body vertical
The optical fiber of straight arrangement, the top and bottom in the tank body is respectively fixed with optical launcher and optical receiver, the optical fiber
Two ends connect the optical launcher and optical receiver respectively, the optical launcher and optical receiver and a metering mould
Block is electrically connected, in the utility model using light different medium interface refractive index it is different the characteristics of make liquid-immersed light
Fine height determines the attenuation rate that light passes through, and then it is immersed to calculate optical fiber by the attenuation rate of light intensity
Height not, and then calculate the real-time yield of producing well.Although the device can realize metering automation, when the oil of measurement
When containing more coloured and lighttight impurity in aqueous mixtures, measuring result error is too big, it is impossible to meet actual oil field tubulars
The needs of reason.
