The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil. Conventional reserves of petroleum are primarily recovered by drilling, which is done after a study of the relevant structural geology, analysis of the sedimentary basin, and characterization of the ...

2023年6月12日 · Petroleum products are fuels made from crude oil and the hydrocarbons contained in natural gas. Petroleum products can also be made from coal, natural gas, and biomass. What petroleum products are made from crude oil?

2023年2月16日，中国石油和化学工业联合会发布数据称，中国炼油产能已超过美国，成为世界第一炼油大国。 石油的性质因产地而异，密度为0.8～1.0g/cm 3， 粘度 范围很宽，凝固点差别很大，沸点范围为常温到500摄氏度以上，可溶于多种 有机溶剂，不溶于水，但可与水形成乳状液。 不过不同的 油田 的石油的成分和外貌可以区分很大。 石油主要被用作 燃油 和 汽油，燃料油和汽油在2012年组成世界上最重要的二次能源之一。 [3] 石油也是许多化学工业产品如溶剂、化肥、 …

石油（英語、拉丁語：petroleum，拉丁語詞源希臘語： petra （岩石）+拉丁語： oleum （油） [1] [2] ），也称原油，是一種黏稠的、深褐色（有时有点绿色的）液体。地壳上层部分地区有石油储存 [3] 。

2025年1月24日 · Petroleum, complex mixture of hydrocarbons that occur in Earth in liquid, gaseous, or solid form. The term is often restricted to the liquid form, commonly called crude oil, but, as a technical term, ‘petroleum’ also refers to natural gas and the viscous or solid form known as bitumen, which is found in tar sands.

Petroleum means rock oil or oil from the earth. Crude oil is found in large underground deposits, in tiny spaces within sedimentary rocks, and near the surface in tar (or oil) sands. Petroleum products are made from crude oil and other hydrocarbons contained in natural gas. Petroleum products can also be made from coal, natural gas, and biomass.

Crude oil, liquid petroleum that is found accumulated in various porous rock formations in Earth’s crust and is extracted for burning as fuel or for processing into chemical products. Crude oil is a mixture of varying hydrocarbons and other chemicals, and its physical properties vary widely.

The petroleum industry, also known as the oil industry, includes the global processes of exploration, extraction, refining, transportation (often by oil tankers and pipelines), and marketing of petroleum products.

Petroleum is a broad term that groups together a combination of organic liquids and gases that is formed after kerogen is heated and compressed over long periods of time. This mix can be fairly complex, but the main gaseous component of petroleum is natural gas - largely methane - whereas the main liquid component is crude oil .

2024年8月28日 · Petroleum-based oil describes a broad range of natural hydrocarbon-based substances and refined petroleum products, each having a different chemical composition. As a result, each type of crude oil and refined product has distinct physical properties.
