In 2014, international oil prices fell sharply, and the world's oil and gas industry entered a downturn cycle. The "four lows" (low price, low return, low investment, and low cost) will become new features of the oil and gas industry in the new era. 1. Global oil supply and demand will remain loose before 2020
Petroleum products have a very wide range of roles and functions in social and economic development, and their refined products have penetrated into all aspects of people's lives and are inseparable. [6] Petroleum is a mixture of different hydrocarbon compounds. Through one-time processing, the simple physical method of atmospheric pressure and vacuum distillation is mainly
Modern petroleum history began in 1846 when Abraham Kisner, living in Atlantic Canada, invented a method of extracting kerosene from petroleum. In 1852, the Polish Ignaci Lukasiewicz (Lgnacy·Ukasiewicz) invented the method of extracting kerosene using more readily available oil. The following year the first modern oil field opened near Klosnow in southern Poland. These inventions
Refining Features (1) Refining production is the production of equipment flow. Oil flows through each equipment along the process sequence, and is decomposed into different fractions under different temperature, pressure, flow, and time conditions to complete each stage of product production. A set of devices can produce several different products at the same time, and
Refining method There are many basic methods of refining petroleum, and only a few main refining methods are introduced here. [6] 1. Distillation: Using the principle of gasification and condensation, the petroleum is divided into various components with different boiling point ranges. This process is called petroleum distillation. Distillation is usually divided into atmospheric distillation
mining technology Well logging engineering applies geophysical methods in the wellbore, and transmits the information on the original conditions and changes in the drilled rock formations and oil and gas reservoirs, especially the information on the distribution and changes of oil, gas, and water in the reservoir, through the cable It is transmitted to the
Mining Features Compared with general solid mineral deposits, there are three salient features: ① The object of exploitation is constantly flowing during the whole exploitation process, and the reservoir conditions are constantly changing. All measures must be carried out according to this situation. Therefore, the whole process of oil and gas field exploitation is a
Oil pumping method: The oil pumping method is mainly deep well pump oil recovery, which can be divided into two categories: rod pump oil recovery and rodless pump oil recovery. ①Rod pump oil production: Rod pump oil production refers to the artificial lift oil production method in which the pumping unit drives the piston of
Gas lift method: The gas lift method means that the formation still has a certain amount of energy, which can drive oil and gas to the bottom of the well, but when the energy supplied by the formation is not enough to lift the oil from the bottom of the well to the surface, the
mining method A long time ago, people used the simplest way to extract oil, just like using a bucket to lift water in a well, and using a winch to extract oil from the oil well. But this method is only suitable for oil wells with very shallow reservoirs, low pressure and low production. For
