Offshore well tombing method

Abstract

The invention discloses a tombing method, in particular to an offshore well tombing method. The offshore well tombing method comprises the following steps: (1) overall scheme design is performed; (2) preparation before drilling: a drilling ship is driven to a preset place; the position of a well is corrected; and a precise coordinate is recorded; (3) an offshore tomb well is constructed; and the barefoot well completion is achieved in advance; (4) a seabed tomb is buried; a cremation urn is put in a second-grade sleeve; and the second-grade sleeve is put in a well bottom tomb; (5) corrosion resistance and pressure increment are performed on the offshore tomb; high-density and low-filter-loss colloidal liquid with stable physical and chemical properties is injected; and a well mouth safety valve is closed; (6) a tombstone is put down to finish tombing; (7) the cremation urn is added; the safety valve is opened; the colloidal liquid is injected in a water separation pipe; and the cremation urn is directly put down; and (8) the cremation urn is transferred; seawater is pumped; the safety valve is opened; an electromagnet tool is put in; and a power supply is communicated to suck the cremation urn to transfer on the ship. The offshore well tombing method has the advantages of saving of the land soil, low cost and long preservation period.

Description

technical field [0001] The invention relates to a funeral method, in particular to an ocean well type tomb method. Background technique [0002] In traditional Chinese culture, the burial of the dead is an extremely important cultural symbol. People are used to expressing mourning and condolences at the grave of the dead. However, with the aging of the population, the number of dead is increasing, and urban development has caused land to become increasingly tense. The supply of land cemeteries to bury the dead is tight, especially in the densely populated eastern coastal areas. For example, all the cemeteries in Shanghai can only be used for more than ten years. After more than ten years, people need to pay sky-high cemetery fees again, otherwise they will face the problem of having nowhere to bury them. Therefore, the development of marine burial methods has become a very suitable path. [0003] The development of marine burial methods is undoubtedly of great significance...

Problems solved by technology

[0004] At present, the world's Shanghai burial methods are mainly to throw the body directly into the sea, or scatter the ashes into the sea, leaving no cemetery for people to mourn, and it is impossible to transfer the ashes of the ancestors; But the decay is serious, and the coffin is often eroded or washed away by ocean currents, so it is difficult to find it after a long time
