Offshore drilling for oil and gas exploration

Offshore drilling for oil and gas production wells and oil equipment measures mainly the following. An artificial island, and more for inshore shallow water, more economical. (2) Fixed mining oil and gas platforms in the form of a pile platforms (such as jacket platform), Sarasota platforms, gravity platforms (reinforced concrete gravity platform, reinforced concrete structure mixed gravity platform). 3 floating mining oil and gas platforms in the form of migration can be classified into platform (also known as the movable platform), such as jack-up rigs, machine for pellets platform and boat platform (ie drilling rigs); does not migrate floating platform, such as tension-type platform, articulated platform. 4 subsea devices: drill subsea wellhead approach will wellhead installed on the seabed, mining of oil and gas by pipeline directly to the onshore oil and gas facilities or enter the submarine set.
