Summary: The wildcat crop that oil field of introductory our country basically uses is metric method, oil of its Central Plains is metric include glass to be in charge of level gauge to measure oil of maximum dose of oily, report, tipping bucket to measure oil; Natural gas is metric the measurement that includes gas of orifice plate lavatory, detached gas to discharge fluid to measure flowmeter of gas, gas to measure gas and water content. Crop of the oil in introducing wildcat to collect a fluid at the same time, gas, water is integrated and metric method and its are relevant technology, elaborate the development trend of wildcat weights and measures technique.
Keyword: Metric aerometer measures wildcat crude oil moisture content is metric unit develops a tendency
Of wildcat crop metric it is one of management of oil field production main job, undertake to wildcat crop accurate, seasonable metric, to mastering oil deposit state, make producer proposal, have important direct sense. Metric method basically has the wildcat yield that at present domestic each oil field uses vitreous canal measures oily orifice plate to measure gas, tipping bucket to measure oily orifice plate to measure gas, two-phase detached density law and three-phase depart are metric the method. As technical progress, oil field needs a function more and more the wildcat with high rate of strong, automation is metric equipment in order to improve the level of management of labor productivity and oil field.
The measurement of 1. crude oil
(1) vitreous canal level gauge measures oil
On oil gas segregator installation grows 80 control and form with segregator connect tubal glass provides level gauge. The certain and main oil inside segregator will be hydraulic pour glass inside the canal, the relation of oily quantity inside the height that according to glass the water inside the canal rises and segregator gains the oily weight inside segregator, the time that measures so that place of ascendant height of face of the fluid inside vitreous canal needs from this, can lose the crop of cipher out wildcat.
Oil of vitreous canal quantity is the traditional method that domestic each oil field uses generally, occupy the 90% above of wildcat gross about. This method equips simple, investment is little, but because use intermittent amount,oily means comes convert crop, bring about error of crude oil system to be 10% ～ 20% . Be in additionally tall hydrous period, be in especially especially tall hydrous period, the platoon fluid after low to enraging fluid to compare wildcat is metric is very difficult, this are metric the operation causes very big inconvenience.
(2) cable measures oil
In glass tubal level gauge measures oily foundation to go up, go up in H of the height that measure oil, issue each to install an electrode, when water rises to next electrode, timing ammeter puts through begin to time, water rises when electrify pole, ammeter is cut off stop to ambulate, record the time T with water ascendant tall H, can measure the output of oily methodological computation producing well according to vitreous canal level gauge.
