Description
Technical Field
The invention belongs to the technical field of offshore oil and natural gas drilling, and particularly relates to a green energy laser drilling device based on a semi-submersible drilling platform.
Background
The ocean contains rich oil and gas resources, and is a huge resource treasury. At the present stage, with the development of marine oil and gas exploration technology, the exploration of reserves is increasing, and advanced exploitation technology is increasingly needed to obtain marine oil and natural gas. Marine drilling and land drilling both contain numerous places where technology is in communication and present many risks and challenges due to the complexity and uncertainty of their drilling environment. On one hand, the ocean drilling faces uncertain factors including seabed low-temperature environment, natural gas hydrate, shallow gas, typhoon and the like, and on the other hand, high technology, high cost and high risk also bring high return and huge economic benefits.
Ocean is used as an important resource treasure house and contains a large amount of green clean energy, wherein the most common energy is wave energy and tidal energy; in addition, in marine environments, there are also green energy sources such as solar energy and wind energy which are relatively common. Green clean energy such as solar energy, wind energy, wave energy and the like can be converted into energy through a specific mechanism under a certain condition, and the green clean energy is converted into electric energy by applying the law of conservation of energy, so that necessary energy is finally provided for drilling operation.
Laser drilling is a novel drilling technology, and equipment such as a drill bit, a casing pipe and the like in the traditional drilling process is not needed. The laser essentially converts energy into photons, the photons are gathered into strong beams, and the laser drilling uses strong laser beams to crush, melt and even evaporate rocks, so that the drilling effect is achieved. Compared with the traditional drilling process, the laser drilling process does not need equipment such as a drill bit, and a ceramic layer well wall can be formed on rocks in the drilling process, so that well blowout harm is prevented to a certain extent, and the drilling safety is improved. In this regard, the potential risks and potential safety hazards of the drilling process to the semi-submersible drilling platform can be effectively avoided, and the method is particularly important for underwater operation of marine drilling. In addition, due to the comprehensive consideration of the economical efficiency of the laser drilling, the application of the laser drilling in land drilling is not popularized yet, however, with the continuous promotion of the research and development of lasers and the breakthrough development of the ultrashort pulse high-power laser technology, on the basis of the more mature laser drilling technology, the unique performance of the laser drilling technology can well meet the requirement of marine drilling, the inconvenience of the traditional drilling technology in underwater operation is avoided, and the laser drilling technology has important practical significance for improving the benefits of the marine drilling.
