  • At present, in the Shunbei oil and gas field in the Tarim Basin of China, 41 oil and gas wells with a vertical depth of more than 8,000 meters have been drilled, and four 100 million-ton oil and gas fields have been established, marking the successful exploration and development of this oil and gas field with the deepest burial in the world.


  • Immediately after oil enters the sea, a series of changes occur, including diffusion, evaporation, dissolution, emulsification, photochemical oxidation, microbial degradation, sedimentation, and formation of asphalt balls. Oil pollution can damage seaside landscapes and baths.


  • Qingdao Haitongda Petroleum Instrument Factory is a comprehensive high-tech enterprise specializing in the design, research, manufacture and operation of experimental instruments and equipment for oil and gas field exploration and development. For more than 40 years, the company has an oil and gas exploration and development equipment technology center and a municipal R&D center, which has the functions of technology development and laboratory.


  • On the 25th, the National Oil and Gas Strategic Research Center and the China Petroleum Exploration and Development Research Institute released the report "Global Oil and Gas Exploration and Development Situation and Oil Company Dynamics (2022)" in Beijing.


  • Santai County held a discussion with PetroChina Southwest Oil and Gas Field Branch on tight gas development projects


  • In order to explore and exploit the oil and natural gas contained in the deep formation, people must use various drilling equipment and tools to drill through the hard and complex formation, which is the main task of drilling work. In order to meet the needs of the rapid development of my country's petroleum industry, it is necessary to drill more wells, drill wells faster, and drill wells to double the drilling speed. To this end, while fully mobilizing the positive factors of people, it is also necessary to provide drilling workers with advanced drilling equipment and tools with good performance, and make full use of modern science and technology to serve oil drilling work.


  • Oil, known as the blood of the industrial age and also known as "black gold", is the main source of energy for current machine power. From the current point of view, the world will extract about 75 million barrels of oil every day, and about 25 billion barrels of oil will be extracted every year to meet people's needs, and this number is still increasing at a rate of 2%-3% per year, which means that in the future More oil will be extracted by humans.


  • Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons in natural occurrences. Petroleum is further divided into crude oil, natural gas, natural gas liquid and natural tar, but it is customary to use "petroleum" as the definition of "crude oil". Petroleum is a viscous, dark brown liquid known as the "blood of industry." There are oil deposits in parts of the upper crust. So what are the conditions for extracting oil?


  • During the drilling process, the drilling fluid or other medium (cementing slurry, etc.) in the wellbore leaks into the formation pores, cracks and other spaces. Loss of circulation is a common complex situation in the well in drilling engineering, and most drilling processes have different degrees of leakage. .Severe lost circulation will cause the pressure in the well to drop, affect the normal drilling, cause the instability of the wellbore, induce the formation fluid to flow into the wellbore and cause the blowout. Therefore, we must take timely measures.


  • Through the study of safety management measures in the process of oil and gas field development, the safety of oil and gas field production can be improved, the occurrence rate of oil and gas field production safety accidents can be reduced, the cost of oil and gas field production can be reduced, and the economic benefits of oil and gas field production can be continuously improved.


  • Loss of circulation refers to a kind of working fluid (including drilling fluid, cement slurry, completion fluid and other fluids) that directly enters the formation under the action of pressure difference during downhole operations such as drilling, cementing, testing or workover. Downhole complex situation. So, what is the reason for the drilling loss?


  • Drilling fluid is a general term for various circulating fluids that meet the needs of drilling work with various functions during the drilling process. Drilling fluid is the blood of drilling, also known as drilling flushing fluid. Drilling fluid can be divided into clear water, mud, clay-free flushing fluid, emulsion, foam and compressed air according to the composition.
