Problems solved by technology

However, in this scheme, there are too many approximate parameters, the physical meaning of each parameter is not clear, and the influence on the changing parameters such as pressure and temperature is not considered, which ultimately affects the method used and the measurement accuracy.
In addition, the use of g-ray measurement methods produced by radioactive sources has a relatively large weakness, that is, there are radioactive safety problems, especially in the current period when the anti-terrorism situation is relatively severe, this weakness is more prominent
[0012] At present, the principle and device for measuring water content and gas content in crude oil with continuous energy X-rays emitted by X-ray machines have not been found in the market

Abstract

The invention discloses X-ray measuring device and measuring method of water content and gas content in a multiphase flow. The measuring device comprises an X-ray apparatus, a computer, a front collimator, a multiphase flow pipeline, a first rear collimator, a detector, a signal amplifier and a multichannel analyzer. The X-ray measuring device and measuring method of water content and gas content in a multiphase flow have high measuring precision, can conveniently and rapidly acquire X-ray signal data penetrating through the multiphase flow pipeline in real time and realize the accurate measurement on a multiphase flow mixing medium according to the principle that different media have different absorbing and scattering conditions on X-rays with different energy.

Description

technical field [0001] The invention relates to a device and method for measuring the water content and gas content index of oil, water, and gas multiphase mixed media in oil pipelines, in particular to a device and method for measuring X-ray absorption and scattering of different energies according to different media The X-ray measuring device and method for measuring water content and gas content in multiphase flow based on the principle are especially suitable for automatic online metering systems in oil field production. Background technique [0002] Crude oil is one of the country's most important strategic materials. Crude oil extracted from oil wells is a mixture of multiphase media such as oil, water, and natural gas. To process this mixture, gas and liquid separation must be carried out first, and the remaining oil and water mixed liquid is dehydrated to obtain refined oil with a very low water content for export or sales. In a series of production activities such...
