Self-lifting type multifunctional ocean platform and work method thereof

Abstract

The invention discloses a self-lifting type multifunctional ocean platform and a work method thereof and belongs to the technical field of marine transportation and ocean engineering technology. The multiple functions of the platform are combined to realize well drilling, well repairing, household self-holding and small-scale drilling. The self-lifting type multifunctional ocean platform mainly comprises a platform upper-layer deck, a machinery deck, cylindrical pile legs, a crane, pile shoes, a helicopter deck, a fore body lateral pushing part, a derrick, a tail thruster, pile shoe containing zones, a pile driver slideway, an LNG tank body, a pile driver, a main machine and the like. The self-lifting type multifunctional ocean platform meets the existing ocean engineering development requirement, achieves various operations such as ocean platform well drilling, well repairing, household self-holding and small-scale drilling, has the all-weather operation capability and long self-holding capability and adopts a cantilever drilling mode and advanced pile leg lifting equipment, drilling equipment and generating equipment. The self-lifting type multifunctional ocean platform is higher in integration capacity, has the well drilling, well repairing and small-scale drilling capacities, has a broad deck space, is provided with a natural gas collecting and compression treatment device and a corresponding power system, and is economical, efficient and high in engineering applicability.

Description

technical field [0001] The invention relates to a self-elevating multifunctional ocean platform and a working method thereof, which belong to the technical field of marine transportation and ocean engineering equipment. Background technique [0002] At present, offshore oil development has entered a new form. In view of the pressure of oil exploitation disputes in the South China Sea, the workload of major workover and adjustment wells on production platforms has increased. The traditional production process is: drilling well→installing jacket→drilling development well and completion→ Installation of production modules and drilling rigs→oil extraction→adjusting wells→oil extraction→well workover→oil extraction, etc. These operations require non-cantilever and cantilever mobile drilling platforms, fixed platform drilling rigs, mobile engineering support platforms, mobile life support The platform and offshore floating cranes have been completed one after another. The traditi...

Problems solved by technology

[0004] In order to solve the problems of low technical content, simple structure, single function, and serious waste of energy, the present invention provides a self-elevating multifunctional offshore platform and its working method. And other functions, and in the process of drilling, it can use its own natural gas to generate electricity and supply energy, and can compress and store natural gas, which can collect energy while reducing energy use. The entire platform has the characteristics of independently completing multiple functions, reducing the number of platforms. The number of times of plugging and unplugging can also reduce the number of platforms used, reduce the cost of the mining process, and have great commercial value
