The evaluation of the four properties (reservoir property, oiliness, fluidity and compressibility) of the shale reservoir is an important research content and basis for unconventional oil and gas exploration and development, while the evaluation of the oiliness and fluidity is a key for exploration and development, and has important significance for realizing the quality evaluation of unconventional reservoir, the research of reserves and source storage configuration relation, and the exploration and development of preferably shale oil dessert and the like.
Methods for evaluating the oiliness of shale oil and tight oil reservoirs are reported in the literature, see (1) , zhang Zhenling, li, etc. "rock pyrolysis analysis" (national standard of the people's republic of China, GB/T18602-2012, 2013, 7, 1); (2) "Petroleum and sedimentary organic hydrocarbon gas chromatography method" (national standards for Petroleum and Natural gas SY/T5779-2008, 12 months 1); (3) Teng Jianbin, liu Huimin, longwei, etc. "control law of oil content by the composition of matter of the depressed shale oil reservoir" ("oil and gas geology and recovery ratio, 1 st 2019); (4) "prestack inverted tight sandstone reservoir prediction and detection of oil and gas properties" (vomit-haar gas, 2012, 1 st phase); (5) Zhang Jinyan "shale oil logging evaluation method and application thereof" (geophysical progress, 2012, 3 rd); (6) Li Xiaomei "quantitative evaluation and prediction of oil and gas contents of Dongying-pit lithology oil and gas reservoirs" (oil and gas geology and recovery ratio, 3 rd period in 2006), etc. The ROCK pyrolysis S1, S2, tmax and other parameters are detected by using ROCK-EVAL 6 type manufactured by French Mo Ji company or raw oil ROCK evaluator manufactured by domestic manufacturer to evaluate the oil content of the reservoir and shale; analyzing saturated hydrocarbon, aromatic hydrocarbon and crude oil total hydrocarbon components and parameters in the rock chloroform extract by adopting a gas chromatography method, and evaluating the types, maturity, oil-containing characteristics and the like of crude oil and sedimentary organic matter matrix; the method (3) adopts petrography and geochemistry analysis means to carry out crude oil occurrence state and substance component analysis on shale oil reservoirs of the upper subsection of the four sections of the sand trapping depression and the lower subsection of the sand trapping depression, and comprises shale oil fluorescent sheet characteristics and scanning electron microscope occurrence state analysis technology; the (4) adopts an integrated technology of seismic data amplitude preservation treatment and prestack inversion to predict the oil-gas properties of compact and shale reservoirs, and is often macroscopic oil-containing evaluation; the shale oil oiliness evaluation is carried out by using a logging method, and the oil gas information which can be detected by a logging technology is weaker due to the small reservoir space of a tight reservoir, so that the oiliness evaluation difficulty is high; and (6) establishing a quantitative prediction model of lithologic trap oiliness by adopting a mathematical geology method of stepwise regression and variable elimination.
