Abstract
The utility model relates to a water content monitor for crude oil. The monitor comprises a measuring pipeline, a gamma ray source, a transmission detector and a scattering detector. In addition, a flow guiding pipe is also arranged in the measuring pipeline, and mixing blades are also arranged in a liquid inlet segment of the measuring pipeline. The flow guiding pipe of the utility model can avoid that a flow state of measured liquid generates variation and secondary flow is reduced, and the mixing blades can cause the liquid entering a measured position to form a homogeneous state. Therefore, the precision, the stability and the accuracy of the monitor can be enhanced, the monitor is more suitable for the on-line precise monitoring of water ratios for the crude oil containing gas, and the crude oil has the advantages of high degrees of viscosity, multivariant flow rates and fast oil-water separation.
Description
The utility model relates to a kind of automatic monitoring instrument, especially a kind of crude oil water containing monitor.
In oilfield exploitation was produced, the measurement of water ratio of producing crude oil was the production and technical indication and the economic target of petroleum chemical enterprise's outbalance, also is the emphasis of petroleum metering work; But especially be still even to this day, the measurement technology difficult problem of petroleum chemical enterprise for viscosity height, flow velocity is changeable, oil and water separation the is fast online precise monitoring of crude oil water content.In the prior art of measuring crude oil water content, sample examination method, capacitance method, microwave method, vibration densimetry are arranged; Wherein the sample examination method is time-consuming, and can not in time understand the situation of change of crude oil water content; It is moisture to adopt microwave method, capacitance method, vibration densimetry etc. to survey, because the site technology condition is limit, its zero drift error is bigger, powerless especially to more crude oil water containing monitoring, is difficult to satisfy the requirement of petroleum metering.At present, adopting more water cut monitor method is the radionetric survey technology, as disclosed crude oil gassiness, automatic water ratio-monitoring instrument in the Chinese patent 93107258.1, this instrument belongs to the moisture measuring instrument under the steady state flow condition, because its structural design limits, be not suitable for viscosity height, flow velocity is changeable, oil and water separation the is fast online precise monitoring of live crude water percentage equally.
The purpose of this utility model is for a kind of improved crude oil water content monitor that improves precision, stability and the accuracy of bearing analysis that carries out on Chinese patent 93107258.1 is provided.
The purpose of this utility model can realize by following measure:
A kind of crude oil water containing monitor contains measuring channel, transmission detectors, gamma ray projector and scattering detector; Be respectively equipped with gamma ray projector and transmission detectors in radial center line symmetry both sides, the sidewall upper edge of measuring channel; Forming an angle with gamma ray projector and transmission detectors place center line and axially on the center line sidewall of certain distance, be fixed with scattering detector with it along measuring channel; The measuring-signal of transmission detectors and scattering detector enters the gassiness, the water percentage that demonstrate tested crude oil mixed liquor after computing machine calculates behind linear amplifying circuit; Also in the measuring channel of fluid to be measured, also be provided with mozzle in addition; In the measuring channel liquid input section, also be provided with stirring vane.
The computing software of computing machine of the present utility model can be by drawing in the Chinese patent 93107258.1.
The utility model has following advantage compared to existing technology:
The utility model is provided with mozzle at the gamma ray projector place of measuring channel pipeline section, and mozzle is that rectangle can be avoided fluid flow pattern at tested segment to change and reduces the secondary flow phenomenon, thereby makes the liquid at tested place form steady flow; The utility model also used stirring vane to stir before liquid enters tested place in addition, thereby made the liquid that enters tested place be the even shape of gas-liquid; The utility model makes it be applicable to viscosity height, the continuous online precise monitoring of flow velocity is changeable, oil and water separation is fast crude oil water containing, gassiness adopting precision, stability and the accuracy that has improved Chinese patent 93107258.1 after the above-mentioned measure.
