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...

Problems solved by technology

[0003] Since the extraction liquid used in the extraction of rock cutting is a toxic and volatile organic liquid (usually n-hexane or polytetrafluoroethylene), it will enter the human body through the respiratory tract, skin, etc., and long-term exposure will cause the operator to suffer from Chronic poisoning such as dizziness, fatigue, and numb limbs can lead to fainting, loss of consciousness, cancer, and even death in severe cases. dangerous

[0004] The application date is November 2, 2002, and the invention patent with application number 02144550.8 (hereinafter referred to as reference document 1) discloses a standard solution automatic preparation device. The standard fluorescent solution configuration device is technically combined with the solution configuration system, the standard bottle sealing system and the control panel to form a standard fluorescent solution preparation device, which solves the problem of long time, low precision, and great damage to the human body. Unable to meet the needs of the logging operation site and other issues

[0005] In the comparison document 1, the standard bottle sealing system is used to seal the standard fluorescent solution with devices such as the sealing lamp head and the pull-out sealing pliers, and then the fluorescence characteristics are analyzed. Although this method solves the sealing problem of the standard fluorescent solution, Before preparing the standard fluorescent solution, it is necessary to use the extraction solution to extract samples such as rock cuttings. The automation of this extraction process is very low, and the sealing problem of the extraction process has not been mentioned in the comparison document. Therefore, to solve the extraction The automation of the process and the sealing of the extraction fluid are urgent problems to be solved for the fluorescence logging equipment
