Description

A kind of filter sand formula oil well metering device

Technical field

The utility model is related to a kind of oil field measurement apparatus, more particularly to a kind of filter sand formula oil well metering device.

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.Due to the fluctuation of some oil wells Liquid output greatly, or containing a large amount of oil-sands and there is interval now As the metering of Liquid output cannot accomplish 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.
