The radio-frequency water-cut analysis device for an oil field has a compact structure, accurate measurement, and can achieve the effect of continuous measurement of a single well on site.
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。 The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
一种油田用射频含水分析装置，如图1所示，包括有壳体1，壳体1内部安装有芯线2，芯线2外围设置有起保护作用的护管3。其中，芯线2上设置有射频信号发生器4，芯线2始端连接设置有信号处理单元5，芯线2末端通过连接体6与探头7相连接。较为优选的，信号处理单元5还连接设置有数据远传模块（图1中未示出），而连接体6的外围布设有起绝缘保护作用的绝缘橡胶套。护管3其始端与壳体1密封相连接，其末端与连接体6密封相连接。 A radio frequency water analysis device for an oil field, as shown in FIG. 1 , includes a housing 1 , a core wire 2 is installed inside the housing 1 , and a protective tube 3 is provided on the periphery of the core wire 2 for protection. Wherein, the core wire 2 is provided with a radio frequency signal generator 4 , the beginning of the core wire 2 is connected with a signal processing unit 5 , and the end of the core wire 2 is connected with the probe 7 through the connecting body 6 . More preferably, the signal processing unit 5 is also connected with a data remote transmission module (not shown in FIG. 1 ), and the outer periphery of the connecting body 6 is provided with an insulating rubber sleeve for insulation protection. The starting end of the protective tube 3 is connected to the casing 1 in a sealed manner, and the end thereof is connected to the connecting body 6 in a sealed manner.
此外，如图1所示，壳体1的侧面上还设置有第一法兰口8以及第二法兰口9，其中，第一法兰口8与油井地面集输管线的井口计量入口相连接；第二法兰口9与油井地面集输管线的井口回流口相连接。 In addition, as shown in Figure 1, a first flange port 8 and a second flange port 9 are also provided on the side of the housing 1, wherein the first flange port 8 is connected to the wellhead metering inlet of the oil well surface gathering pipeline. Connection; the second flange port 9 is connected with the wellhead return port of the oil well surface gathering pipeline.
在本发明所示的油田用射频含水分析装置工作过程中，分别开启第一法兰口以及第二法兰口，待检测油井液流入壳体与护管之间的介质流通通道内；而探头则向被测介质中发射稳频恒幅的电磁波。当电磁波穿透被测介质，透过的电磁波强度会随油井液中水含量的不同而对应产生变化，信号处理单元通过检测变化后的电磁波即可确定油井液中水含量的多少。 During the working process of the radio frequency water analysis device for oil field shown in the present invention, the first flange port and the second flange port are respectively opened, and the oil well fluid to be detected flows into the medium circulation channel between the shell and the protective pipe; and the probe Then emit electromagnetic waves with stable frequency and constant amplitude into the measured medium. When the electromagnetic wave penetrates the measured medium, the intensity of the transmitted electromagnetic wave will change correspondingly with the water content in the oil well fluid. The signal processing unit can determine the water content in the oil well fluid by detecting the changed electromagnetic wave.
值得注意的是，为提高信号处理单元的运算速度，该信号处理单元可选用采用高速的单片机技术和24Bit高精度A/D转换器。同时，利用先进的数学模型与高效算法，对含水量计算结果进行校准，最终得出精确的油井液含水量。而后，进一步的可将上述计算结果通过数据远传模块传送至服务器或数据中心，从而完成对油井液的远程监控。 It is worth noting that, in order to improve the operation speed of the signal processing unit, the signal processing unit can use high-speed single-chip microcomputer technology and 24Bit high-precision A/D converter. At the same time, use advanced mathematical models and efficient algorithms to calibrate the calculation results of water content, and finally obtain accurate oil well fluid water content. Then, the above calculation results can be further transmitted to the server or data center through the data remote transmission module, so as to complete the remote monitoring of the oil well fluid.
