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
Drilling plays a very important role in various tasks of petroleum exploration and oilfield development, such as finding and confirming oil-bearing structures, obtaining industrial oil flow, proving the oil-bearing area and reserves of proven oil-bearing (gas) structures, obtaining the geological data and development data of related oil fields, and finally bringing oil from underground to
Bio-Oil Theory (Lomonosov Hypothesis) Studies have shown that the generation of oil takes at least 2 million years, and among the oil reservoirs discovered today, the oldest is 500 million years old. But some oil was produced in the Jurassic. In the long history of the earth's continuous evolution, there are some "special" periods, such
Northeast China Daqing Oilfield: Located in the west of Heilongjiang Province, in the middle of Songnen Plain, is located in Harbin, Qiqihar City. The field is 140 kilometers long from north to south and 70 kilometers wide from east to west, with a total area of 5,470 square kilometers. In March 1960, the CPC Central
Distribution of oil resources in my country my country's oil resources are concentrated in the eight basins of Bohai Bay, Songliao, Tarim, Ordos, Junggar, Pearl River Estuary, Qaidam, and East China Sea Shelf; natural gas resources are concentrated in Tarim, Sichuan, Ordos, East China Sea Shelf, Qaidam, and Songliao , Yinggehai, Qiongdongnan and Bohai Bay
Distribution of oil resources in the world On the national stage, oil, as an important resource and strategic reserve material, has always attracted the attention of all countries, and oil has also been the fuse of many major wars in history. Below are the top ten countries with the largest oil reserves in the world
