1.重力Specific Gravity 跟水来比,用API来衡量,水是10 degrees API 重力为1{(141.5/ Specific Gravity) – 131.5} 那么原油的分类有: · Bitumen沥青 (<10) · Heavy (10˚-20˚) · Medium (20˚-35˚) · Light (35˚-50˚) · Condensate 50˚+ 2.粘稠度Viscosity(Measured in Centis...
Petroleum includes crude oil, natural gas, and heavy oil. Petroleum refineries convert crude oils and other input streams into dozens of refined (co)products. Two properties are especially useful for quickly classifying and comparing crude oils: API gravity (a measure of density) and sulfur ...

The API gravity, viscosity, and SARA (saturates, aromatics, resins, asphaltenes) compositions of the utilized crude oils (obtained from a local oilfield) are shown in Table 1. Table 1. API gravity, viscosity and SARA compositions of the utilized crude oils. Empty CellLight crude oilHeavy ...
API gravity is measured as the inverse of the density of a petroleum liquid relative to water. The higher the API gravity, the lower the density of the petroleum liquid, meaning lighter oils have higher API gravities. The increase in light crude oil production is the result of the growth in...

• By relative density (or API gravity): Light, medium, and heavy. What do “paraffnic”, “naphthenic” and “intermediate” crude oils mean? Paraffnic, naphthenic and intermediate crude oils are difierentiated by the proportion of hydrocarbon molecules they contain. Paraffnic crude contai...
Amber to green to black liquid, depending on source. Crude oil is volatile and flammable, and may cause flash fires. If ingested, aspiration may occur, causing lung damage or death.Health Effects: The information below represents an overview of health effects caused by overexposure to one ...
2.1 Crude oil API gravity Crude oil density is defined as the mass of a unit volume of the crude at a specified pressure and temperature and expressed in g/cc. In typical oil reservoirs, the oil density decreases with pressure depletion until it reaches the lowest value at the bubble point...
