Drilling BOP And Control System During oil drilling, it is installed on the wellhead casing head to control high-pressure oil, gas, and water blowout devices. When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (shut down). When the heavy mud is pressed into the drill pipe, there is a four-way under the ram, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the ejection of high-pressure oil and gas.

It was learned from the press conference of the “Shandong Forum†held on March 16 that the machinery industry, which is the pillar of “Shandong Manufacturingâ€, has been fully recovered so far, and the economic benefits and other indicators have reached the pre-crisis level and become “made in Shandongâ€. "A big highlight."
According to Liu Weidong, president of the Provincial Machinery Industry Association, in 2009 the province's machinery industry completed an added value of 340.527 billion yuan, an increase of 25.64% over the same period of the previous year; realized profits of 87.91 billion yuan, an increase of 30.33%.
From the perspective of the whole province, all the 11 small industries affiliated to the machinery industry achieved positive growth. The largest increase was in heavy mining machinery, which increased by 31.36% and the automobile industry increased by 26.64%.
The economic benefits have grown significantly and have begun to enter a virtuous cycle. Since the second half of 2009, the growth rate of benefits has reached or exceeded the normal year growth level before the financial crisis. Among them, the best growth rate of efficiency in the automotive industry, the growth rate reached 51.72%. Ranked nationwide, the province's machinery industry's total output value, sales revenue, and profitability are the second in the country.
In order to fully demonstrate the new achievements of the Shandong machinery industry, the fifth "Shandong System Fair" hosted by the provincial government will open in Jinan on March 25. At that time, 95 sets of the first set of equipment in the province, including the first set of extremely thin coal seam electromechanical integration and high-efficiency mining key technologies and equipment, Lunan Machine Tool Turning and Milling Compound Machining Center will be unveiled.
Its types are divided into ordinary blowout preventer, universal blowout preventer and rotary blowout preventer. The universal blowout preventer can be activated in emergency situations to deal with any size of drilling tools and empty wells; the rotary blowout preventer can realize the blowout and drilling operation. In deep well drilling, in addition to two ordinary blowout preventers, universal blowout preventers and rotary blowout preventers are often added, so that three or four combinations are installed at the wellhead.
Annular Blow-out Preventer Annular Blow-out Preventer is usually equipped with a large gate with a ram-type blowout preventer. During operation, a sealed annular space is formed between the pipe string and the wellbore. When there is a pipe string in the well, it can also be separated The well is closed, but it will not work after several times of use, and long-term shut-in use is not allowed.
All of the 11 small industries affiliated to the machinery industry achieved positive growth, with the largest increase being heavy mining machinery, an increase of 31.36%. Indicators such as the economic benefits of the machinery industry have reached the pre-crisis level.
