The invention relates to a sea fracturing method. The method includes firstly performing fracturing geological design; mounting a fracturing
wellhead, and mounting a fracturing
wellhead high-pressure pipeline and connecting to a
high pressure hose; loading fracturing equipment, suspending the fracturing equipment to a
deck and fixing, concentrating the fluid container area, arranging a fluid feeding pump, a sand container, a sand mixing pump pry, a high-pressure injecting pump unit, a
high pressure pipeline
assembly and the like sequentially behind, preparing water, feeding material and preparing
fracturing fluid; after a fracture construction ship arrives at a platform, adopting a
tail laying manner,
mooring, connecting to the
high pressure hose at the
gunwale of the platform, starting all high
pressure injection pumps, inspecting circularly, and performing the pipeline pressure test; performing fracture construction according to the designed pump injection progress after the pressure test is qualified. The high pressure pipeline
assembly is an
assembly connected the high
pressure injection pumps and high
pressure injection pipeline, and the high pressure injection pumps are
power equipment injecting fracture fluid into oil pipes through the high pressure pipeline assembly and the high pressure pipeline. The method is applied to oil testing and fracturing construction of sea exploration and development wells.
