Description

Detachable fluid pipe and magnetic resonance probe

Technical Field

The utility model relates to a fluid measurement engineering field, it is further, relate to one kind and can dismantle fluid pipe and magnetic resonance probe, especially relate to one kind can carry out on-line measuring's magnetic resonance fluid analysis appearance with dismantling fluid pipe and magnetic resonance probe to the flow, composition and the nature of fluid.

Background

The Nuclear Magnetic Resonance (NMR) technology is a mainstream indoor fluid component analysis technology at present, has the advantages of non-invasive, environment-friendly, efficient and accurate measurement means, and has good prospects when being applied to industrial fields for online measurement of complex mixed-phase fluids. The multiphase flow NMR flowmeter developed under the background realizes the application of the NMR technology in the field of oil and gas metering for the first time.

The NMR fluid analyzer adopts an on-line non-contact measurement method, in the working process, a fluid pipe and a field manifold form a completely closed connection, the measured fluid flows through the fluid pipe and is measured at the same time, and no choke element exists in the pipeline, so that the non-invasive measurement mode is realized. Due to the particularity of the NMR detection technique, the fluid tubes of the NMR fluid analysis instrument must be of a non-metallic material and the tubing cannot produce an NMR response.

The working principle of the NMR fluid analyzer is that a static magnetic field generated by a permanent magnet in the fluid analyzer and a pulse radio frequency field emitted by an antenna act on fluid component atomic nuclei under the same frequency to generate resonance, the signal change is measured, and the fluid content is analyzed in a mode of measuring the flow rate in a flowing state and measuring the components in a static state. In the working process of the instrument, the fluid pipe and the field manifold are in completely closed connection, a measured fluid passes through the fluid pipe and cannot contact with any sensor in the probe, the probe can perform magnetic resonance detection on the fluid pipe while detecting the fluid in the fluid pipe, so that the requirement that the material of the fluid pipe cannot generate signals for magnetic resonance is met, the phenomena of wax precipitation, blockage and the like cannot occur in the fluid pipe, and otherwise the detection result of the instrument can be seriously influenced. However, as the most important application scenario of the NMR fluid analyzer is in the petroleum field, the NMR fluid analyzer detects oil-gas multiphase flow produced underground, and as the underground crude oil contains macromolecular compounds, the fluid pipe is likely to have wax precipitation, scaling, corrosion and other phenomena when used for a long time or at a low environmental temperature, which seriously affects the detection accuracy of the analyzer. Because the NMR probe is made of permanent magnet materials with high magnetic induction intensity, the pipeline maintenance is not recommended on the premise of not disassembling the fluid pipe in consideration of the safety of manual operation. In order to shorten the manual operation time as much as possible, the disassembly and replacement of the fluid pipe are required to be as convenient, fast and easy to operate as possible.

Aiming at the problem that a fluid pipe in an NMR fluid analyzer is inconvenient to replace in the related art, an effective solution is not provided at present.

Therefore, the inventor provides a detachable fluid pipe and a magnetic resonance probe by virtue of experience and practice of related industries for many years, so as to overcome the defects in the prior art.
