【摘要】 智能井各层井筒内实时压力、温度、产量与含水率等数据是指导调控匹配各层产量的重要参数,缺一不可。由于井下情况复杂,目前智能井系统普遍没有安装井下流量计与密度计,因此无法得知各层油藏参数、产量与含水率数据。基于质量守恒、动量守恒理论,结合传热学、热力学、渗流力学等理论,建立层段油管内与油套环空内流体能量守恒方程,利用各层井筒内油套环空与油管内流体单点压力温度实时监测数据分析出各层油藏参数并计算出各层产量与含水率。结合1口智能井实际生产数据,根据各层井筒内实时监测的压力与温度数据计算出各层油藏参数、产量与含水率。通过常规生产测井结果与实时压力温度数据分析结果对比,结果吻合度很高,证明该分析模型实现了智能井实时生产测井的功能,解决了现场实际生产问题。更多还原

【Abstract】 Real-time pressures,temperature,productions,water cut and other data in the boreholes of each producing formation of the intelligent wells are the important parameters to guide the adjustment and control the production allocation of every layer,so none can be excluded.Due to the complicated conditions in the downholes,the current intelligent well systems are not generally installed downhole flowmeter and hydrometer,so the data such as oil reservoir parameters,productions and water cut of each layer cannot be obtained.Based on the mass and momentum conservation theories,and moreover combined with theories of thermal conduction,thermodynamics,fluid mechanics and so on,the fluid energy conservation equation is established in the casing and tubing annuli of the intervals,the real-time pressure and temperature monitored data of each point of the fluids in the annuli of the boreholes of each layer are adopted to analyze and obtain the parameters stated above.Combined with the practical production data of one intelligent well and according to the real-time tested pressure and temperature data in the wellbore of each producing formation,the reservoir parameters,productions and water cut are calculated.By comparing the normal production test results with those of the analyses on the actually measured data,the matched degree is pretty higher,all the achievements stated above prove that the analyzing model has realized the functions of the real-time production test in the intelligent well,so the problems of the field production and operation are well solved.更多还原
