Abstract

The invention discloses a detection device for the oil extracting speed of an oil well based on ultraviolet detection and belongs to the technical field of oil recovery. The detection device for the oil extracting speed of the oil well comprises an oil transportation pipeline for detecting and an ultraviolet detector, wherein the oil transportation pipeline for detecting comprises a conventional oil transportation pipeline and a detection pipeline; and the ultraviolet detector comprises a solar panel, a storage battery, an ASE (Amplified Spontaneous Emission) broadband light source, an input single-mode fiber, a Zno nano-rod-micro-nano-fiber hybrid waveguide, an output single-mode fiber and a spectrometer. A method comprises the following steps: firstly, enabling the detection pipeline inthe oil transportation pipeline for detecting to be communicated with a oil transportation path at a polish rod; then performing whole week running on a beam-pumping unit crank for one week in accordance with a prescribed cycle and preserving oil in the detection pipeline; then starting a heating device and performing spectrum detection on an optical signal outputted from the output single-mode fiber by utilizing the spectrometer; and finally, determining oil pump capacity through the relationship obtained by calibration. The detection device disclosed by the invention can realize the technical aim of detecting the oil extracting speed of the oil well.

Description

technical field [0001] The invention relates to a detection device for the oil output speed of an oil well based on ultraviolet detection, which belongs to the technical field of oil recovery. Background technique [0002] China National Petroleum Corporation and Daqing Oilfield Co., Ltd. pointed out in their invention patent application number 2016105892521 "A Combination Working System Swabbing Operation Method of Beam Pumping Units" In the case of insufficient fluid, it is often necessary to reduce the theoretical displacement of a single well. [0003] In fact, earlier, Harbin Sophie Electric Technology Co., Ltd. has disclosed two technical means to reduce the theoretical displacement of a single well. Non-sucking operation method of pumping unit" and the invention patent with application number 2015108388310 "Dynamic Variable Stroke Operation Method of Beam Pumping Unit Based on Non-circumferential Crank Movement". [0004] It can be seen that under the condition of i...
