Description
Technical field
The invention provides a kind of bottom bracket shell device, be specifically related to a kind of marine oil field production tree bottom bracket shell device.
Background technology
China's oil drilling and extracting equipment manufacturing enterprise have accumulated rich experience in the land equipment preparation process of decades, for offshore oil equipment Design manufacture waterborne is laid a good foundation, and the production domesticization of achievement unit subset.But, the production domesticization usage degree of the part sea oil drilling and production equipment of current China is only applicable to the shallow sea area of more than 300 meters, for the marine site, deep-sea of more than 2000 meters, also there is larger gap at the technical elements of deepwater oilfield drilling and extracting equipment in China, especially the key equipment of the drilling and extracting equipment of the South China Sea that petroleum resources storage capacity is huge still needs import compared with western developed country.
Along with the increase of the depth of water, more and more higher to the requirement of offshore oil underwater kit, connect each other tightr between each several part, 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 goes into overdrive at Eleventh Five-Year Plan further to offshore oil exploration and exploitation, starts late; 2, the research of equipping offshore oil of offshore oil equipment Manufacturing is just at the early-stage, is substantially in study and understanding stage; 3, Innovation Input is not enough, and highly qualified professional lacks; 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, strengthen independent research innovation, strengthen R&D expenditure, strengthen and introduce the inexorable trend that high-level personnel's dynamics is petroleum equipment manufacturing enterprise.
Summary of the invention
The invention provides a kind of marine oil field production tree bottom bracket shell device, utilize marine oil field production tree bottom bracket shell device of the present invention designing requirement to manufacture marine oil field production tree bottom bracket shell device, improve mechanical performance and sealing performance significantly, adapt to the demand of deepwater oilfield high pressure, high flow rate, there is corrosion resistance.
Technical solution of the present invention is: this marine oil field production tree bottom bracket shell device comprises five-way body, filter cylinder assembly, flange, adpting flange assembly, welding neck flange, valve bonnet seal circle, stud, nut, the locking of screw thread anaerobism glue, double thread, nut, gasket ring, filter screen warning sign, screw, installs welding neck flange and adpting flange assembly in five-way body both sides.
In marine oil field production tree bottom bracket shell device of the present invention, between five-way body and welding neck flange, gasket ring is installed.
In marine oil field production tree bottom bracket shell device of the present invention, valve bonnet seal circle is installed between five-way body and flange.
Beneficial effect of the present invention is: structure is simple, and mechanical performance is high, and sealing performance is strong, and corrosion resistance is strong, safe and reliable, adapts to offshore oil production tree deep-sea oil producing operation.
