Micro-photoluminescence spectra measurement mechanism of liquid inclusion enclave

Abstract

A microscopic fluorescence spectrum measurement device of fluid inclusions includes a computer with the data processing, a fluorescence spectrophotometer which comprises an optical fiber base, a microscope objective and an inverted fluorescence microscope which is provided with a carrier at the interior, the invention is characterized in that the device further includes a high-precision adjusting bracket which is arranged on the inverted fluorescence microscope, a reflective microscope objective is arranged on the high-precision adjusting bracket, the reflective microscope objective is connected with an A port of a Y-shaped optical fiber cable, other two ports of a B port and a C port of the optical fiber cable are respectively connected with an optical fiber excitating port B and an optical fiber transmitting port C of the optical fiber base in the fluorescence spectrophotometer, and the reflective microscope objective is coaxial with the microscope objective of the inverted fluorescence microscope. The invention integrates the microscopic positioning, the single color excitation and the fluorescence collection into a whole, the structure is simple and reasonable, the regulation is easy, the cost is low, the device can measure the fluorescence spectra of single hydrocarbon inclusion and the groups, as well as the other inclusions including the biological materials.

Description

technical field [0001] The invention relates to a microscopic fluorescence spectrometer, in particular to a microscopic fluorescence spectrometer measuring device for fluid inclusions. Background technique [0002] The so-called fluid inclusions refer to the microfluids that originally existed in the reservoir when the mineral crystallized and grew, which were captured by the diagenetic cement and wrapped in the defects or pockets of the mineral crystal lattice, authigenic minerals developed in the reservoir rocks Inclusions and the traces of fluid substances that endow them in a bound state Fluid inclusions record the properties, components, physicochemical conditions and geodynamic conditions of hydrocarbon fluids and pore water. Since the inclusions are formed without the addition of foreign substances and the outflow of their own substances, they can be studied as the original ore-forming fluids and have reliable primary properties. Therefore, regular sampling in the hor...

Problems solved by technology

[0004] Although there is a micro-fluorescence device for measuring single oil and gas inclusions that uses a deep ultraviolet upright fluorescence microscope, but because it must use a very expensive deep ultraviolet microscope, the cost of the entire device is too high, which greatly limits its application.
