In order to conveniently understand a kind of liquid spike equipment with function of measuring that the embodiment of the present application provides, first isotope tracer technique is simply introduced, so-called isotope tracer technique is the radionuclide (or stability nucleic) that utilizes of isotopic tracing and their compound, to nature exist corresponding common element and compound between chemical property and biological property be identical, just there is different nuclear physics character., so that it may to mark as one with isotropic substance, therefore make the tagged compound containing isotropic substance (such as mark food, medicine and metabolic substd etc.) and replace corresponding non-marked compound. Utilize the nuclear physics character of radio isotope constantly release characteristic ray, just can follow the trail of it at any time in body or external position, quantity and transformation thereof etc. with nuclear detector, although stable isotope does not discharge ray, but its difference to the quality of common corresponding isotropic substance can be utilized, pass through mass spectrograph, gas chromatography instrument, the analytical instrument of quality such as nucleus magnetic resonance measure. Radio isotope and stable isotope all can be used as tracer agent (tracer), but, stable isotope is lower as its sensitivity of tracer agent, and obtainable kind is few, and costly, its range of application is restricted price; And not only highly sensitive as tracer agent with radio isotope, measuring method is simple and easy to do, can be accurately quantitative, accurately locates and meet the feature such as physiological condition of studied object.
In oil reservoir logging process, these characteristics of isotope tracer technique are utilized oil well each layer position situation to be monitored, in actual applications, it is necessary to discharge isotopic tracer in oil well to be measured. Prior art discharges the equipment of isotopic tracer, owing to lacking metering outfit, in use can quantitatively not discharge isotopic tracer, on the one hand owing to isotopic tracer is expensive, therefore blindly release can cause certain waste, the logging cost made promotes greatly, the toxicity that the opposing party is certain owing to isotopic tracer has, and therefore environment too much also can be caused certain pollution by release. A kind of liquid spike equipment with function of measuring that the embodiment of the present application provides, by the gauge assembly of particular design, it is possible to easily realizing the requirement of quantitatively release, the element of wanting most of gauge assembly is all common element, and making method is simple, with low cost.
