电阻热采物理模型研究

研制了一套二维电阻热采物理模拟系统． 该系统包括五个组成部分：模型主体、注入系统、采出系统、抽真空系统和温度测量系统．其模型主体的体积为４００ ×４００ ×３６ｍ ｍ ． 在模型底部开有若干个温度测量孔，通过测量孔将测温热电偶放置在模拟油藏中． 电热油藏的物理模拟过程中的温度测量采用自行研制的温度场数据采集系统，实现了在线监测． 可利用该系统研究电场提高原油采收效率的方法及其影响因素，更适合于电热油藏的机理性研究．

APhysicalModel for Therm alRecovery of Oil Reservoirs by Electric Heating

A tw o-dem ension physicalsim ulating system is developed for electric heating of oilreservoirs. The system consistsofthem ain body ofthe m odel, injection system , production system , pum ping vacuum sys- tem and tem perature m easuring system . The size of the m ain body of the m odelis 400×400×36m m . The tem perature ofsim ulated reservoirscan be m easured by tem perature field data gathering system , so thetem per- ature m easuring ison-line. The m odelcan be used forthestudy ofthem oving law ofreservoirin the processof electric heating, and itcan also provide technicalparam etersforthe electricheating ofrealreservoirsby sim ulating the realreservoirs in proportion. The tem perature field distributions ofsim ulated reservoirsunder different heating conditions are studied by m eansofthem odel. Theprinciple ofdeterm ining electric heating pow erisalso given. The m odelcan also be used forthe study ofthe electric heating m echanism ofreservoirs.
