The invention relates to a low-pressure-drop high-efficiency static mixing device and an oil blending method that are beneficial to oil blending. The static mixing device includes a pre-mixer, and the pre-mixer includes a container body and two or more symmetrical Arranged inlet connecting pipes; wherein, each of the two or more inlet connecting pipes forms an included angle of 45° to 50° with the axial direction of the pre-mixer, and passes through the inlet at the corresponding position on the container body of the pre-mixer and The interior of the container body is in fluid communication. Using the method of the present invention, the component oil products collected in the blending head are throttled and pressurized into multiple strands of materials, which respectively enter the pre-mixer through the inlet joints of the pre-mixer, and the materials are tangential along the pipe wall in the form of high-speed swirling flow. The direction is diagonally tangentially and symmetrically sprayed into the pre-mixer, and after full contact with the pre-mixing, it enters the static mixer for further mixing. The static mixing device of the present invention can ensure efficient and sufficient mixing of various component oil products, reduce density stratification, and make product mixing more uniform.

The invention discloses a sesame seed smashing device.The device comprises a shell, a screen arranged in the shell, and a smashing blade arranged in the shell, wherein the shell is obliquely arranged, an opening is formed in the top of the screen, the smashing blade is arranged in the screen, the top of the smashing blade is connected and fixed to the shell, the screen and the shell are spaced, and the screen and the smashing blade are spaced; the space between the screen and the smashing blade serves as a feeding channel, the space between the screen and the shell serves as a discharging channel, the bottom of the screen is connected with a transmission shaft, and the transmission shaft drives the screen to rotate; a discharging port is arranged on the side wall of the bottom of the shell, and a feeding port is arranged on the top of the shell.The device has the advantages that smashing speed is increased, and oil generation during smashing is prevented; smashed sesame seeds with granularity meeting the discharging requirement are discharged in time through the screen, repeated cutting or grinding of finished granules in the smashing device is effectively reduced, and oil generation is further prevented.

The invention discloses an evaluation method based on effectiveness of a shale reservoir. The method comprises: determining the lithofacies as a basic evaluation unit according to the characteristics of the shale oil reservoir; selecting the oil production property, the storage property, the modifiability and the flowability as evaluation contents; and further performing influence factor analysis by the system, preferably selecting organic carbon content, hydrocarbon generation potential, crack type and development strength, pore type and surface porosity, diagenetic action, relative brittleness coefficient, brittleness index and critical flow aperture as evaluation parameters, and obtaining the shale reservoir type by adopting a gray fuzzy mathematical method.

The invention discloses a method for evaluating the formation and evolution of terrestrial mud shale oil in a large freshwater lake basin. The method uses conventional drilling cores and geological experiment analysis, pressure-preserved and sealed coring, and frozen sample oil content calibration and logging technology. Combined method to evaluate shale oil content recovery, vertical sweet spot layer and plane sweet spot area; use depth, Ro, kerogen, chloroform bitumen "A", free oil, adsorbed oil, gas-oil ratio and other parameters , the formation and evolution evaluation model of continental shale oil was established, which met the needs of shale oil exploration. This method evaluates that the mass conversion of adsorbed oil to free oil at Ro1.1%-1.6% is the most favorable stage for the formation of shale oil, and shale oil at mature and highly mature stages is 1.5-3.5 times that of the classic oil generation model. The "sweet spots" of shale oil in the Liao Basin have been selected and breakthroughs in exploration have enabled the exploration depth to be extended to 2600m and the area of ​​sweet spots to be expanded by 1.2 times, laying the material foundation for large-scale exploration of continental mud shale oil in large freshwater lake basins.

The method for reducing aromatic hydrocarbon content in diesel oil in residual hydrogenation equipment is characterized by that the residual oil and hydrogen gas are fed into residual catalytic hydrogenation reactor, and the material flow obtained after reaction is fed into thermal high-pressure separator and separated into gas phase material flow and hydrogenated residuel oil, and gas phase material flow is mixed with diesel oil raw material, and fed into diesel oil catalytic hydrogenation reactor, and the reaction material flow is fed into cold high-pressure separator, and separated into gas and refined diesel oil generation oil, the gas is cleaned, pressurized and returned into residual hydrogenation reactor for circular use, and the refined diesel oil generation oil can be separated to obtain the diesel oil product whose aroamtic hydrocarbon content can be reduced by above 60%.
