Automatic fluorescence logging analyzer

Abstract

The present invention discloses an automatic fluorescence logging analyzer, which comprises an optical processing module, a central control module and a power source, wherein an automatic liquid preparing apparatus for automatically preparing a standard fluorescent liquid is further arranged in the automatic fluorescence logging analyzer and comprises an automatic liquid preparing device and a liquid conveying device for transferring a prepared standard fluorescent liquid, the automatic liquid preparing device comprises an injection arm, an injection pump and a rotatable object placement frame, the injection arm is connected to the injection pump in a sealed manner, a sample bottle with the sealed top portion is placed on the object placement frame, the injection arm injects an extraction liquid into the sample bottle and passes through the liquid conveying device comprising a liquid sucking pump and a liquid sucking arm, the liquid sucking arm sucks the standard fluorescent liquid in the sample bottle, and the liquid sucking pump sucks the standard fluorescent liquid in the liquid sucking arm and transfers to the optical processing module, such that the effects of whole-process extraction solution sealing and automatic extraction are achieved.

Description

technical field [0001] The invention belongs to the field of automatic fluorescence analysis, and more specifically relates to a logging instrument for oil exploration and development. Background technique [0002] Quantitative fluorescence mud logging instrument is a kind of equipment for detecting, analyzing and discovering oil in the process of drilling. It is a commonly used detection instrument in the process of oil drilling and exploration. The obtained spectrum is analyzed to obtain parameters such as oil content and oil quality of the petroleum sample. In the prior art, the working principle of the quantitative fluorescence mud logging instrument is: put the drilling cuttings and other samples into the sample bottle after screening, pour the extract into the test tube and shake or centrifuge the sample bottle to make the rock The oil in the cuttings is fully extracted by the poured extract, and the extract solution that has been extracted from the cuttings is introd...
