Synchronous experimental analysis device for oil content and fine components of shale

Abstract

The invention relates to a synchronous experimental analysis device for oil content and fine components of shale, thereby solving a problem that existing experimental devices are lack. The experimental analysis device is characterized by comprising an oil content detection unit, a trapping and pyroelectric release unit, a fine component detection unit and an oil content and fine component synchronous analysis control unit. According to the experimental analysis device, quantitative shale samples are placed in a pyrolyzing furnace through a sample injector to be heated and pyrolyzed, and hydrocarbon enters an FID detector through a quantitative flow divider to detect the oil content; the other path enters a trapping pipe to be frozen and enriched; heating and heat releasing are carried out,separating is carried out in an analysis column, and fine components are detected by an FID detector; and thus the synchronous analysis of the oil content of the shale and the rock or the fraction content of any section and the fine molecular components of the shale and the rock is automatically completed; the device is used for evaluation of oiliness and fluidity and comparative research of oilsources, and provides a new geological experiment means for optimization and formation mechanism research of 'desserts' of shale oil and tight oil so as to meet the requirements of unconventional oiland gas exploration on geological experiment technologies.

Description

technical field [0001] The invention relates to oil and gas geological experiments, in particular to a simultaneous experimental analysis device for mud shale oil content and fine components, and belongs to the field of unconventional oil and gas exploration. Background technique [0002] In recent years, unconventional oil and gas resources such as tight sandstone oil (referred to as tight oil), shale oil, tight sandy conglomerate gas (referred to as tight gas), and shale gas have achieved large-scale development, pushing the global oil industry into the conventional and unconventional oil and gas resources. A new stage of equal emphasis. The evaluation of the "four properties" (reservoir property, oiliness, fluidity, and compressibility) of shale reservoirs is an important research content and basis for unconventional oil and gas exploration and development, and the oiliness and fluidity evaluation is the key to exploration and development. It is of great significance for...
