Description
Technical field
The present invention relates to offshore oil gas drilling equipment technology field, more particularly to a kind of horizontal bit change in seabed is more
Changing device.
Background technology
With the shortage of landing field petroleum resources, coastal countries are explored and have been opened to Marine oil and gas resource successively
It adopts, and has gradually become the main trend of domestic and international oil and gas industry development with exploitation to the exploration of Marine oil and gas resource.In addition, with
China's economy to grow continuously and fast, petroleum resources insufficient supply by as hinder economic development principal contradiction, for improve oil
The occupancy volume of gas resource, the exploration and exploitation of marine oil and gas have become the strategic emphasis that China realizes energy sustainable development.
The exploitation of marine oil and gas is developed so far, and drilling well exploitation is still the major way of oily gas exploitation.A bite oil/gas well is from opening
Completion is got into, following three groundworks need to be carried out：Broken bottom rock puts down fragmented rock (i.e. landwaste) migration to ocean
Platform, complete well cementation, and drill bit be the key that in drilling engineering to fractured rock, formed pit shaft rock crushing tool.In the prior art
In, it, need to be old by shaft bottom when drill bit is worn by stratum or drill bit encounters the bad grounds such as hard formation, abrasive layer, rammell
Drill bit rises and is drilled into ocean platform to replace green bit；When trip-out, need to using hydraulic tongs, shackle removes one by one by drill pipe joint, from
And old drill bit is made to be promoted to ocean platform, and the old drill bit being worn is replaced on ocean platform, or replace and complexity
The old drill bit that stratum does not match that.After the completion of old bit change-over, tripping operation need to be carried out, when lower brill, need to use hydraulic tongs
Drill pipe joint is upper buckle-shaped at drill string one by one, to make green bit lower going-into-well bottom.Behind green bit lower going-into-well bottom, again turn on pump into
Row drillng operation, and then the purpose realized and improve bit speed, reduce drilling well overall cost.
However replace that the trip-out that old drill bit brings, tripping operation time are long, increase marine oil gas well drilling period and
Labor intensity is improved, drilling cost is considerably increased.
