Description

Two-dimensional quantitative fluorescence detector

Technical field

The utility model relates to the on-the-spot oil gas evaluation appts of a kind of oil field prospecting, particularly a kind of two-dimensional quantitative fluorescence detector.

Background technology

Rationing fluorescent logging is one of on-the-spot important means of finding oil gas, evaluation oil gas of oil field prospecting, utilized the fluorescent characteristic of oil, obtain parameters such as sample concentration, oil by the fluorescence intensity that detects oil sample, for the oil field well logging provides important detection means and reference data.There is defective in traditional quantitative fluorescence detector aspect a lot, as light source, domestic for a long time quantitative fluorescence detector adopts all be xenon short-act lamp or tungsten lamp as light emitting source, its luminescence efficiency is low, need the xenon lamp of 150W excited sample to send fluorescence, and trigger voltage is big, need to insert special start-up circuit, and thermal value is big, cause sample volatile, usually need to add cooling air unit, need the environment of friction, no magnetic interference to work, cause machine volume bigger than normal; And for example traditional quantitative fluorescence detector adopts the PMT detecting device, though it is highly sensitive, needs light-dividing device, all can produce uncertain factor in links such as Installation and Debugging and carryings, if damage, position change can the lowering apparatus work efficiency.

Summary of the invention

Problem in view of above existence, the utility model proposes a kind of two-dimensional quantitative fluorescence detector, concrete technical scheme is: a kind of two-dimensional quantitative fluorescence detector, comprise light source power, Switching Power Supply, cold light source, optical filter, sample cell, CCD detecting device, computing machine and optical fiber, it is characterized in that: optical filter is fixed on the sample cell upper end, light source power links to each other with cold light source, Switching Power Supply links to each other with the CCD detecting device, cold light source, sample cell, CCD detecting device are connected in turn by optical fiber, and the CCD detecting device links to each other with computing machine by the USB mouth.

The beneficial effects of the utility model are: the heat dissipation problem that has solved instrument without any need for refrigerating plant.And long service life, the light path of utilizing optical fiber to form has reduced the optical noise of system greatly, has improved signal to noise ratio (S/N ratio), and machine volume is little, in light weight.
