Description

A kind of self-elevating drilling platform based on truss framed leg

Technical field

The present invention relates to a kind of offshore oil and construction of natural gas fields device, is particularly the self-elevating drilling platform of 300ft about a kind of truss framed leg, operating water depth.

Background technology

Equip as most important shallow sea oil and gas development, self-elevating drilling platform (JACK-UP) has the characteristics such as adapt to different ocean bottom soil conditions and larger depth of water scope, stationkeeping ability is strong, operating flexibility, removable performance are good, playing the part of more and more important role in the marine oil and gas exploration and development, its quantity accounts for 60% of mobile offshore drilling unit, is main force's equipment of offshore oil field probing.

China since the phase at the beginning of the sixties in last century investigation and prospecting of offshore petroleum resources.Exploitation through decades, zone, the more shallow Bohai Sea of depth of water offshore oil field development is tending towards saturated at present, in the darker East Sea of the depth of water and the oil field at the South Sea, because China's deep-sea oil gas development technique falls behind, lack the necessary probing of deep-sea oil gas resource, exploitation and produce equipment, so recovery percent and on average to verify rate relatively low, most area also is in state to be developed at present.

Along with the raising of offshore oil exploration and exploitation technology and the lifting of Chinese overall national strength, the petroleum resources at the large-scale development East Sea and the South Sea becomes the important content of China's energy strategy.In the East Sea and the South Sea due to Offshore depth of water major part in about 70-200m, therefore very large to the demand of the offshore boring island quantity more than the 300ft operating water depth.

China is aspect the Basic Design of jack-up unit at present, still there is larger gap with Foreign Advanced Lerel, outstanding behaviours only has autonomous Design achievement for the equipment of shallow sea (operating water depth is below 150 feet) oil and gas development in present China, operating water depth is in the design of 300 feet and above self-elevating drilling platform and build 100% and adopt the foreign patent design, so far also there is no the deep water truss leg platform of 300 feet (more than reaching) of autonomous Basic Design, so be badly in need of development and innovation at the self-elevating drilling platform design field.
