Among them, the most representative of Daqing crude oil, low sulfur, high wax content, high pour point, can produce high-quality kerosene, diesel oil, solvent oil, paraffin oil and commodities. 其中,最有代表性的大庆原油,硫含量低,蜡含量高,凝点高,能生产出优质煤油、柴油、溶剂油、润滑油和商品石蜡。
Compounded reservoir blockage removal agent HGA-2 is developed for removing multiple precipitates of organic substances, inorganic salts, clay minerals, and etc in low permeable reservoirs of high pour point and high viscosity oil through acidizing, dissolution, heat and gas generation, and other functions. 双液法解堵剂HGA-2用于解除高凝高粘低渗油层中有机质、无机盐及粘土等多种沉积物造成的堵塞,具有酸化、溶解和放热放气等多种功能。
The operation result showed that the lube base oil products with high viscosity index and low pour point were produced from the 2nd and 4th vacuum column side cuts and the deasphalted oil of Daqing crude oil. 结果表明,以大庆原油的减二线、减四线和轻脱沥青油为原料,得到了粘度指数高、倾点低的润滑油基础油产品。
In order to adapt low temperature performance of CNG or gasoline convertible-fuel engine oil, several pour point depressants were added to the same base oil, and their flowing point, apparent viscosity and pumped-temperature were measured. 对几种降凝剂在同一种基础油中的倾点、表观粘度、边界泵送温度进行了探讨,来满足CNG/汽油两用燃料发动机油低温性能的要求。
These unconverted oik were superior feedstocks for ethylene manufacturing by steam cracking, and catalytic re-forming feedstocks with higher aromatics potential and jet fuels or low pour point gas oil were obtained simultaneously. 该尾油是蒸汽裂解制乙烯的优质原料,并兼得芳潜含量较高的重整原料、喷气燃料或低凝柴油。
Penglai 19-3 oil field is characterized by crude oil with high surface density, high viscosity and low pour point, high oil saturation pressure, little pressure difference between formation and saturation pressures, moderate dissolved gas-oil ratio and distinct biodegradation and water washing. 地面原油密度较大、黏度较高、凝固点低,地层原油饱和压力较高、地饱压差小,溶解气油比中等,原油的生物降解和水洗作用较为明显。
Crude oil with low pour point is different from low ( un) mature crude oil which is rich in high carbon number alkanes. 低凝固点原油区别于富含高分子量正构烷烃的低(未)成熟原油。
