1976年8月24日美国专利3,975,941号《油井产量计量方法》提出,用手提式热—电仪表遥测出油管线放空火炬的热强度,然后查表可求得油井产量。发明者认为,这种方法用于偏远的单井测量或海上油井,由于不再采用计量分离器可节省2～2.5万美元。事实上,计量分离器重达4.5～11吨,而有效使用时间甚至不到1％。工作原理:主要仪表是一个自带电源的,手提式辐射热感应器。这种热感应器包括一个热—电变换器。变换器变换感应器输出为电流,然后提供计量机构,可读
U.S. Patent No. 3,975,941, August 24, 1976, entitled “Well Production Metering Methodology,” proposes using a portable thermoelectric meter to telemetrically measure the thermal strength of a flared torch in an oil pipeline and then looking up the table to determine the well’s production. The inventor believes that this method is used for remote single-well measurements or offshore wells, which can save between $ 2 and $ 25,000 as metering dispensers are no longer used. In fact, weighing separator weighing 4.5 ~ 11 tons, and the effective use of time even less than 1%. How it works: The main instrument is a self-powered, portable radiant heat sensor. This thermal sensor includes a thermo-electric transducer. Converter Transducer output current, and then provide a metering mechanism, readable
