由于新疆油田公司SAGD试验区现场测压井数多,工作量大,科研人员前期所使用的测试毛细管大多采用人工补氮气方式,现场存在一定的局限性。为提高现场测试工作效率,降低操作人员劳动强度,新疆油田公司工程技术研究院科研人员成功研制了热电偶温度补偿压力测量补氮控制仪,解决了上述问题,该控制仪于2013年10月获得国家知识产权局专利授权。毛细管测压由于具有耐高温、抗腐蚀、井内无任何电子元件器和高精度器件特点,而被广泛应用于SAGD井及其它高温井中,但毛细管阻塞是毛细管测压的顽疾,所有使用毛细管测压单位和企
Due to the large number of in-situ manostat wells and heavy workload in the SAGD pilot area of Xinjiang Oilfield Company, most of the test capillaries used by researchers in the early stage were man-made nitrogen gas reservoirs, so there are some limitations on site. In order to improve the efficiency of on-site testing and reduce the labor intensity of operators, the researchers of Engineering Research Institute of Xinjiang Oilfield Company successfully developed the nitrogen compensation controller for temperature compensation of thermocouple and solved the above problems. The controller was obtained in October 2013 State Intellectual Property Office patent license. Capillary piezometry is widely used in SAGD wells and other high temperature wells due to its high temperature resistance, corrosion resistance, absence of any electronic components and precision components in the well, but capillary occlusion is a chronic problem of capillary pressure measurement.
