Abstract
The invention relates to a large-diameter thread screwing device for offshore drilling. The four corners of an upper platform device are each provided with a stand column through hole and are in threaded connection with stand columns. A through hole is formed in the center of the upper platform device. A clamping and rotating device is connected with the upper platform device through hydraulic cylinders. A hydraulic motor is installed on one side of the clamping and rotating device. A lower clamping well-head template and slip device is composed of two opposite semi-ring-shaped well-head templates and slips. Protecting pins are installed on the well-head templates. The slips are installed on the inner walls of the well-head templates. A chassis device is located at the bottom. The upper platform device, the clamping and rotating device, the lower clamping well-head template and slip device and the chassis assembly are sequentially and fixedly connected through the stand columns from top to bottom. The large-diameter thread screwing device has the advantages that the design is ingenious, the structure is reasonable, the working efficiency is effectively improved, the labor intensity is relieved, the defect of an unreasonable down-hole technique during platform operation is overcome by the large-diameter thread screwing device, and the safety of drilling construction is sufficiently guaranteed.
Description
Technical field
The present invention relates to drilling engineering field, be specifically related to a kind of offshore drilling large calibre threads spin-up chain.
Background technology
In recent years, along with expanding economy and growth in the living standard, the demand of oil is rapidly increased by people, various countries pair
The speed of oil exploitation is the most constantly accelerated.In order to play water proof, every mud, every husky effect, generally make in Process of Oil Well Drilling
With conduit, and in order to improve production efficiency, joint of generally burn-oning at conduit two ends, this also makes the demand to water separation pipe joint
Amount continues to increase.But, during afloat drilling platforms operation, the nipple of heavy caliber high pulling torque is fastened as the biggest asking
Topic, platform space is little, and marine riser caliber is big, and this is also to bring the biggest problem to upper button.Nowadays the heavy caliber of platform connects
Detain work on head and substantially lean on winch and hydraulic pressure chain wrench, thus occur that joint is eccentric, the phenomenon of thread alternating, this danger coefficient height,
The upper button method of waste personnel labour force is inherently eliminated, and my company have developed a kind of can directly use, peace at platform
Complete, full automatic Offshore drilling large calibre threads spin-up chain, it can effectively improve bit speed, reduce and work into
This, realize full-automation for China's offshore platform operation and provide safeguard.
Summary of the invention
For solving the deficiencies in the prior art, the present invention provides a kind of offshore drilling large calibre threads spin-up chain.
The technical scheme is that a kind of offshore drilling large calibre threads spin-up chain, including upper platform device, on
Clamping and rotary apparatus, lower clamping and template and slip system, chassis assembling device, stand column device, upper platform device
Four angles have column through hole, and threaded with column, and upper platform device center has through hole；Clamping and rotary apparatus
Being connected by hydraulic cylinder with upper platform device, clamping has through hole with the center of rotary apparatus, and the surrounding in hole is uniform is fixed with hydraulic pressure
Cylinder, hydraulic cylinder by synchronous valve control, the side of clamping and rotary apparatus equipped with hydraulic motor, lower clamping and template and slips
Device is two split semiorbicular templates and slips composition, uniform equipped with oil cylinder, on template inside template
Equipped with guard pins, template inwall is equipped with slips；Bottom is base apparatus, upper platform device, clamping and rotary apparatus, lower folder
Tight and template passes sequentially through column from top to bottom and is connected fixing with slip system, chassis chunk.
Described column through hole is the hole of φ 1200mm, and hole wall is-7 °.
It is made up of six hydraulic cylinders with the clamp system rotated.
Hydraulic motor has two, high-speed motor, a zero motor.
The oil cylinder of template has six.
Template is connected by stiffness spring with slips.
The invention has the beneficial effects as follows: design ingenious, rational in infrastructure, effectively improve work efficiency, alleviate work strong
Degree, is the ideal tools gone into the well of Offshore Operation riser pipe, and this device is irrational when also compensate for platform operations goes into the well
Technique, fully ensures the safety of wellbore construction.
