Description
Technical field
This utility model relates to measuring apparatus field, especially, is a kind of constant volume type one-well metering structure.
Background technology
The metering of oil well output is an important process in field production management, and oil well output is carried out accurately, measured timely, to grasping oil reservoir situation, formulates production decision, has important directive significance.The method for production metering of oil wells that current domestic each oil field uses 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..Along with the progress of technology, oil field has increasing need for function is strong, automaticity is high oil well measurement equipment to raise labour productivity and the management level in oil field.Measurement (1) the gauge glass gauging of single-well crude oil is installed a root length about 80 on gs-oil separator and constitutes the gauge glass of communicating pipe with separator.In separator, hydraulic pressure is fallen in glass tubing by the oil of constant weight, the weight of oil in the relation of oil mass obtains separator in the height risen according to water in glass tubing and separator, thus record the time required for liquid level lifting height in glass tubing, oil well yield can be converted into.Glass tube oil gauge is the traditional method that domestic each oil field is commonly used, accounts for more than the 90% of oil well sum.The method equipment is simple, small investment, but owing to using the mode of interval gauging to convert yield, causing crude system error is 10%～20%.Additionally at high water-cut stage, particularly at ultra-high water cut stage, the most difficult for the discharge opeing after the oil well measurement that gas liquid ratio is low, this metrological operation puts to no little inconvenience.(2) telegram gauging is on the basis of gauge glass gauging, gauging height H one electrode of upper and lower each installation in regulation, when waterborne be raised to bottom electrode time, timing ammeter opens up beginning timing, waterborne when being raised to electrode, ammeter cuts off stopping and walking about, and record water rises the high time t of H, then can calculate oil well yield according to the method for gauge glass gauging.(3) tipping bucket gauging tipping bucket oil-measuring apparatus is mainly made up of oil jug, enumerator etc..One bucket translates into oil extraction when filling, and another charge of oil that struggles against, such iterative cycles carrys out accumulation oil mass.Tipping bucket metering can cannot cause measuring inaccurate by the cleanest for oil and connect the gap of oil and cannot be connected due to the oil in tipping bucket after upset is toppled over, and oil well yield also cannot real time measure, but interrupted counting.
