Waxy crude oil is characterized by high pour point and poor flow properties, which bring great difficulty to the oil exploitation and transportation. In this study, the fluidity of waxy crude oil with the pour point of 47掳C was highly improved by emulsification with synthetic formation water ...
1.Which of the following is true about petroleum formation? A. Microscopic organisms that live in mud produce crude oil and natural gas. B. Large amounts of oxygen are needed for petroleum formation to begin. C. Petroleum is formed when organic material in sediments combines with decaying orga...
As crude oil is one of the commodities which has been financialized deeply, the active international market involves millions of investors from the world. What kind of impact will the international crude oil price have on the crude oil price in China? Based on the spot price of Daqing oil ...
This paper analyzes the group component,the saturated hydrocarbon chromatogram and the biomarkers of the crude oil of Paleogene Dongying Formation in the Wenliu area of the Dongpu depression and the results show that the extractable matter,that is,saturated hydrocarbon from the oil sand of Dongying ...
[20]. The viscosity of crude bio-oils increases rapidly by heating, which leads to bio-oil polymerization, phase separation, and coke formation[21]. Crude bio-oils contain a large amount of water (15–30 wt%) coming from free water in biomass andcondensation reactionsduring production[22]....
发明人: MEBES BRUNO 摘要: In a disinfection method for petroleum and petroleum products, propylene oxide is used as active substance. The process is particularly suitable for inhibiting the undesirable growth of microorganisms when petroleum is extracted.收藏...
During chemical EOR operations, when the concentration of surfactant is above critical micelle concentration (CMC), the formation of micelles will occur leading to a pronounced decrease in IFT. This reduction in IFT will displace the adsorbed oil ganglia from the pores. Thus, the oil ganglia coale...
The materials exhibit high ionic conductivity and thermal stability due to the nature of the cationic moieties, thus rendering this class of new materials as an attractive alternative to develop ion-conducting membranes.Similar content being viewed by others Formation of hierarchically ordered structures ...
Mango, 1990, Mango, 1992, Mango, 1994 proposed a steady-state catalytic process to explain the chemical origin of light hydrocarbons in petroleums and the parent–daughter scheme was established and modified for the formation of C7 hydrocarbons. In the scheme, Mango defined several parameters, inc...
CO2flooding crude oil may generate abundant foams in oil field separators after depressurization. A large amount of foams occupies most of the space in a separator and spends much time to burst, which, in turn, reduces the separation efficiency of the separator. Moreover, the incomplete gas-liq...
