Description
Technical field
The utility model provides a kind of four-way, is specifically related to a kind of deepwater oilfield wellhead assembly rising four-way.
Background technology
China's oil drilling and extracting equipment manufacturing enterprise has accumulated rich experience in the equipment preparation process of the land of decades, for offshore oil equipment Design manufacture waterborne, lays a good foundation, and has realized the production domesticization of part equipment component.But, the production domesticization usage degree of the part sea oil drilling and production of China equipment is only applicable to 300 meters of above shallow sea areas at present, for 2000 meters of above marine sites, deep-sea, China compares the drilling and extracting equipment of the huge South China Sea of existence larger gap, especially petroleum resources storage capacity also at the technical elements of deepwater oilfield drilling and extracting equipment key equipment with western developed country still needs import.
Along with the increase of the depth of water, more and more higher to the requirement of offshore oil underwater kit, between each several part, connect each other closelyr, design and manufacture difficulty obviously strengthens, and new technology also emerges in an endless stream.China's offshore oil equipment mainly contains the following aspects with the gap of World Developed Countries: 1, country just further goes into overdrive at Eleventh Five-Year Plan to offshore oil exploration and exploitation, starts late; 2, offshore oil equipment Manufacturing is just at the early-stage to the research of offshore oil equipment, substantially in study and understanding stage; 3, research and development insufficient investment, highly qualified professional's disappearance; 4, research and development lack use support, and research progress is slow; 5, China's basic industries are poor, and particularly carft of construction research is relatively backward.
Be tending towards above-mentioned reason, strengthening independent research innovation, strengthening R&D expenditure, strengthen introduction high-level personnel dynamics is the inexorable trend of petroleum equipment manufacturing enterprise.
Summary of the invention
The utility model provides a kind of deepwater oilfield wellhead assembly rising four-way, utilize deepwater oilfield wellhead assembly rising four-way of the present invention to manufacture deepwater oilfield wellhead assembly, improve significantly mechanical performance and sealing performance, adapt to the demand of deepwater oilfield high pressure, high flow rate, there is corrosion resistance.
