Rock pyrologger and pyrolytic analysis method

Abstract

The invention belongs to the technical fields of rock pyrolysis and component analysis and in particular relates to a rock pyrologger and a pyrolytic analysis method. The rock pyrologger is characterized by comprising a pyrolytic detecting system, a gas analysis system connected with the pyrolytic detecting system and a sample residual analysis system connected with the pyrolytic detecting system. According to the rock pyrologger and the pyrolytic analysis method disclosed by the invention, various indicators of S0, S1, S2, S3, S4 and Tmax can be tested at one time by using one sample, and S0, S1 and S2 components can be subdivided; the highest splitting temperature can reach the national standard of 800DEG C; in addition, the rock pyrologger has the advantages of high precision, high stability, high detection precision and high analysis speed; the rock pyrologger can be widely applied to scientific research institutions and oil fields for detection analysis, can adapt to field severe conditions and the like; the blank of domestic instrument of the kind is filled in, and the urgent demand of the domestic scientific research institutions on the instrument is met.

Description

technical field [0001] The invention belongs to the technical field of rock pyrolysis and component analysis, and in particular relates to a rock pyrolysis analyzer and a pyrolysis analysis method. Background technique [0002] In the process of oil exploration in our country, timely, accurate and quantitative evaluation of oil and gas characteristics of formation is the goal and requirement of mud logging work. In recent years, with the progress and development of exploration, the complexity of formations has gradually been recognized. At the same time, the comprehensiveness of on-site mud logging data has increased, so it is urgently needed to be able to analyze the exploration formations during mud logging. At present, my country's oil exploration industry has been going on for decades, and many oil fields have entered or are facing to enter the stage of mid-to-late development of oil fields. Therefore, the exploration of highly mature or over-mature source rocks in variou...

Problems solved by technology

However, the current domestic rock pyrolysis analysis instruments can only measure source rock S 0 Content, S 1 Content, S 2 content, the maximum cracking temperature Tmax value or get the reservoir rock S 0 , S 11 , S 21 , S 22 , S 23 Five indicators, unable to measure the content of carbon dioxide at 300°C-400°C and carbon monoxide at 300°C-500°C (the sum of the two is S 3 content), unable to thermally evaporate hydrocarbons at the same time (S 0 +S 1 ) and pyrolysis hydrocarbons (S 2 ) components, and the final temperature of pyrolysis is 600°C, which cannot meet the current national standard "GB / T18602-2012 Rock Pyrolysis Analysis", which requires a maximum cracking temperature of 800°C, and is not suitable for highly mature or over-mature hydrocarbon sources Rock Detection Analysis
