asphaltene content) and wax structure (carbon number distribution of wax, branched-chain degree of wax); the weak pipeline shear can improve the flowability of some crude oil but also can deteriorate the flowability of other crude oil, which is related to crude oil composition and wax structure...
Geochemical Characteristics of Crude Oils from Zao-V Oil Measures in Shenjiapu Oilfield terms of the fractional composition of crude oils, GC characteristics of saturated hydrocarbon fraction of crude oils and the characteristics of their ... 尹伟,林壬子,林双运 - 《地球化学学报:英文》 被引量: ...
In this study, four core samples of different age, mineral composition, TOC (total organic carbon) content and thermal maturity were taken in four target strata of shale oil reservoirs (Table1). The samples include (1) Niobrara marl form the 3 Berthoud State well, between chalk sections C a...
(2) The petroleum source analysis has indicated that the crude oil in the Lunnan and Tahe oilfields are derived from the source rocks of the Middle and Upper Ordovician. (3) Three generations of oil inclusions from the Lunnan oilfield have been recognized and dated.中国科学:地球科学(英文版)...

However, the synergistic effect of chemical composition, concentration and in particular the pH of the brine in oil recovery during LSWI remains not well understood. In addition, there is a lack of low salinity studies in Brazilian sandstone rocks and light paraffinic crude oils of low acid/...
the analysis of the elements’ content determined the minerals’ composition and the genesis of their deposits. However, the method is costly and it is time-consuming to prepare samples. Analyzed using THz-TDS, the terahertz spectra of the samples are obtained through the interaction of terahertz...
2.2. Oil Spill Behavior and Calculation Principles 2.2.1. Transfer Process The transport of oil particles involves both expansion and drift processes, and the composition of oil particles does not affect these processes [18]. Expansion movement: Oil film expansion is calculated using the modified Fa...
In the control diet (CON) used in the experiment, no fishmeal was replaced. The composition of the basal diet is shown inTable 1. Sardine fish meal, anchovy fish meal, tankage meal, poultry by-product meal, soybean meal, wheat gluten, and soy protein concentrate were used as the feed ...
The production of SNG from biomass is generally considered to be made of three main process stages: gasification of the lignocellulosic biomass into raw syngas (mainly composed of H2, CO, CO2 and CH4 on a dry basis), methanation (catalytic conversion of the syngas into crude SNG) and ...
