1. Oil\/Gas Field Surface Test and Metering Equipment Skid<\/b><\/strong><\/span><\/p>\n Introduction<\/strong><\/span><\/p>\n Oil\/gas filed surface test and metering facility system is mainly used to measure yield, wellhead pressure, and physical property during temporary flow of production in the test process of flowing well in the initial stage of oil\/gas field exploratory development so as to analyze oil reservoir.<\/span><\/p>\n High pressure mixture of oil, gas and water flows out from wellhead assembly firstly through choke manifold and throttle for depressurizing and then through high pressure throttle heater or heat exchanger, and then flows through angle type choke valve with the help of two-level heating coil for heating for further depressurizing and finally enters test separator.<\/span><\/p>\n Inside the test separator, the gas\/liquid mixture is primarily separated into gas and fluid phases by means of energy consumption part at inlet. Gas goes into gas phase space, from which the liquid drop particle with the size of more than 100 \u00a6\u00ccm is separated at the rear space through the coalescence and rectification functions of stuffing, and then goes into mist eliminator to separate the liquid drop with the size of more than 10 \u03bcm. The natural gas with the liquid less than 0.05 g\/Nm3<\/sup>\u00a0flows out of test separator via outlet. The natural gas is measured by senior orifice plate and three-pen Oil\/Gas Field Surface Test and Metering Equipment Skid recorder. Separator pressure is controlled by pressure controller and pressure regulating valve and then the natural gas flows to flare system.<\/span><\/p>\n Liquid that enters liquid phase space flows pass washboard and the gas bulb with the size of more than 100\u03bcm is separated. The oil and gas mixture settles in the separation and settling chamber for a while. The separated crude flows over baffle board and into buffering chamber and then out of test separator through vortex breaker and oil outlet. The crude is measured by two parallel-connected positive displacement flowmeters or turbine flowmeters. Oil level is automatically controlled on site by liquid level controller and two liquid level regulating valves with parallel connection and then the crude flows into measuring tank.<\/span><\/p>\n Oily water flows out of test separator via drainage outlet and is measured by positive displacement flowmeter or turbine flowmeter on site. Interface between oil and water is automatically controlled on site by oil\/water interface controller and interface controller and interface regulating valve, and then the oily water flows into cesspool.<\/span><\/p>\n Features:<\/span><\/strong><\/p>\n <\/p>\n Oil\/Gas Field Surface Test and Metering Equipment Skid<\/span><\/strong><\/p>\n Technical Parameters:<\/span><\/strong><\/p>\n \u00a0Media Physical Property and Processing Capacity<\/span><\/strong><\/p>\n <\/p>\n 2. Test Separator Skid (Three-phase or Two-phase)<\/b><\/strong><\/span><\/p>\n Introduction<\/span><\/strong><\/p>\n The test separator skid consists of test separator, control valves and relevant pressure\/temperature\/liquid level measurement instrument and data acquisition system. It is applied to separate oil\/gas well production fluid into oil, gas and water and then to measure them.<\/span><\/p>\n Features<\/span><\/strong><\/p>\n <\/p>\n 3. Measurement Calibration Skid<\/b><\/strong><\/span><\/p>\n Introduction<\/span><\/strong><\/p>\n The measurement calibration skid is applied to calibrate oil\/water flowmeter of test separator and calculate correction coefficient.<\/span><\/p>\n When crude oil yield is so small that the flowmeter cannot measure flow rate, the fluid can be switched into measuring tank and the flow rate can be calculated by level gauge.<\/span><\/p>\n When the viscosity of crude is large, crude oil can be swerved to measuring tank and then is transferred by pump for load.<\/span><\/p>\n The measuring tank is double compartment normal atmosphere cuboid tank. Bypass manifolds are equipped at inlet and outlet. Steam heating coil is at the bottom. At the front of each compartment, there is level gauge, while at the rear part, there is manway for waste. Each compartment has one manway, flame arrestor on top. Outlets of the flame arrestors are connected to be one pipeline, which goes beyond safe area.<\/span><\/p>\n Specifications<\/span><\/strong><\/p>\n <\/p>\n 4. High Efficiency Specialized Separator for Oil\/Gas Field<\/b><\/strong><\/span><\/p>\n Light and medium oil high efficiency oil-gas-water three-phase separator<\/span><\/p>\n Introduction<\/span><\/strong><\/p>\n The separator is mainly used to separate the oil-gas-water mixture produced from oil well into three phases: purified oil, associated gas and qualified sewage. It can be applied at the following sites:<\/span><\/p>\n onshore oil-gas field:<\/span><\/strong><\/p>\n offshore oil-gas field:<\/span><\/strong><\/p>\n The mixture of oil, gas and water enters high efficiency three-phase separator gas-liquid separation area. The associated gas will be removed by gravity and collision separation. Oil-water mixture enters plate groove liquid distributor (patent component) from the clapboard bottom, then flows into separation chamber. In separation chamber, through two phase coalescence and rectifying stuffing, oil-water will remove the remaining water in the<\/span><\/p>\n oil and the oil in the sewage. The purified oil enters oil chamber, flows out of three-phase separator. The qualified sewage enters water chamber, flows out of three-phase separator. After removing liquid by mist eliminator, the associated gas from the separated chamber flows out of three-phase separator.<\/span><\/p>\n \u00a0Features<\/span><\/strong><\/p>\n Features of three-phase separator<\/span><\/strong><\/p>\n For crude oil with medium and high water cut, after once three-phase separator dehydration, the water cut in oil will be less than 0.3%, and the oil in sewage will be lower than 300 mg\/L<\/span><\/p>\n \u00a0Technical parameters<\/span><\/strong><\/p>\n \u00a0Media Physical properties<\/span><\/strong><\/p>\n <\/p>\n 5. Medium and Heavy Oil High Efficiency Oil-Gas-Water-Sand Separator<\/span><\/strong><\/p>\n \u00a0Introduction<\/span><\/strong><\/p>\n The separator is mainly used to separate the thick and extra thick oil-gas-water-sand mixture produced from oil well into four phases: qualified thick oil and extra thick oil, associated gas, qualified sewage and sand. It can be applied at single well producing test site, metering station, oil transfer station, joint station, CEP platform and land terminal.<\/span><\/p>\n Light and Medium Oil High Efficiency<\/span> In the gas-liquid separation area, the incoming oil-gas-water-sand mixture separates the associated gas. The separated gas separates the liquid drop with diameter > 100\u03bcm across the second stage stuffing, then through the mist eliminator to remove the liquid, and flows out of the equipment from gas outlet. The separated gas-water -sand mixture from the gas-liquid separation area flows into tube type liquid distributor. After through the second stage coalescence stuffing and first rectifying separation stuffing to remove free water and part emulisifier and remove the oil in sewage, oil and water will separately flow into oil chamber and water chamber, then flow out of the equipment separately from oil outlet and water outlet. The separated sand from the oil and sewage water first flows through “V”\u00b1 type stuffing, then through the sand collecting chamber to sand collecting component, through the internal pressure helping sand-drainage equipment to drain out of the equipment.<\/span><\/p>\n \u00a0Features<\/span><\/strong><\/p>\n \u00a0Medium Oil Technical Parameters<\/span><\/strong><\/p>\n\n
