Description
Technical field
The utility model belongs to ocean platform technical field, more particularly to a kind of jack up for preventing jetting pipeline from blocking
Ocean platform shoe Chong Zhuan mechanisms.
Background technology
In the exploration and development of Offshore petroleum resource, jack-up unit is widely used, and occupies main force status.Jack-up unit
A kind of mobile ocean platform, available for operations such as the drilling well of offshore oil, well workover, formation testing and pilot productions, have it is mobile flexibly,
The advantages that stability is good, and daily rental fee is relatively low, it usually needs carry out the operations such as pitching pile, pile pulling in different waters.
Self-elevating ocean platform is inserted spud leg and shoe at sea bed certain depth by way of ballast, to provide platform
Required bearing capacity, it is ensured that platform operations safety.When current well location operation is completed, it is necessary to carry out pile pulling operation, and then will be flat
Platform is displaced to next target well location.In order to smoothly complete pile pulling operation, especially in the case where shoe supporting course is argillic horizon,
It is generally necessary to which the system of rushing carried using jack-up unit carries out punching stake, and then reduce pile extraction resistance especially shoe bottom
Absorption affinity acts on.Jack-up unit rush an effect for ensure platform pile pulling operation be smoothed out it is significant, will
Directly affect platform pile pulling job scheduling, or even safety.
The nozzle that existing jack-up unit rushes stake system is directly arranged in lower surface and the upper table of shoe in the form of opening
Face.Although being furnished with the protective cover of arc outside nozzle, the problem of can not still avoiding jetting pipeline from being blocked by seabed soil, cause
Rush stake effect be difficult to reach, pile pulling it is difficult, reduce pile pulling operation timeliness, or even pile pulling operation occur not normally completing.Specially
Sharp CN 101302763A rush at stake mouth installation and rush stake valve, hydraulic means etc. each, and structure is numerous and diverse, and installation, operation, maintenance are not
Just, and delivery port, washing pipe, the blockage problem of rushing stake mouth etc. still have, further, since shoe inner space is very limited, it is existing
Field feasibility is restricted.The A of patent CN 103696423 add jetting pipeline, but asking of blocking of jetting pipeline, protective cover
Topic still has.The A of patent CN 102383426 are transformed a mode of rushing for shoe upper surface, and pile pipe is rushed in existing shoe
The problem of line blocks still has.
The content of the invention
