Technical field
It is specifically a kind of quick without marine riser based on circulating fluid the utility model relates to oil gas drilling technical field
Core-drilling system.
Background technique
Oil gas survey with ocean Science Drilling visit the depth of water be it is deeper and deeper, deepwater drilling, ultra deepwater drilling have been more than a few kms,
In conventional deepwater drilling, the method for generalling use marine riser, using marine riser method have the disadvantage that 1) it is this using every
Water pipe well system is mating complicated, complicated for operation, and load acts on well head soft formation, influences well head stability, and conventional water proof
When keeping mud (also known as drilling fluid) closed cycle in pipe, causes mud circulation pressure drop and increase, to narrow space Density Window
Construction causes greatly to restrict, very strict to closed circuit drilling well-head sealing requirements, and meets the emergency release of emergency case
Program is complicated, and risk is high；2) it is turned round using conventional open circuit direct circulation, open circuit drilling mud flow to drill bit by drilling rod from ship
Place, flows out to the annular space between drilling rod and the borehole wall by hydrophthalmia, annular space is directly discharged in seawater from well head without closed loop, mud, no
Only mud consumption is very big, and mud is at high cost, and drilling fluid directly arranges sea and pollutes environment, violates environmental legislation；3)
It is easy to be impacted by mud at the borehole wall especially well head, stability cannot get effective guarantee, and mud speed rate is insufficient, causes to drill
In landwaste carry effect it is poor, easily cause bit freezing, rock core is easy chip off-falling, and the quality of core sample is difficult to ensure；4) deep water just follows
When loopback turns coring operation, the rigid drilling rod of several kms turns round in the seawater to be influenced by ocean current etc., is easy to swing back and forth, and is bored
Head drilling direction is affected, and goes hither and thither, and reduces bit life, and influence core recovery percentage；Even if 5) taken using rope
The heart also only accelerates coring efficiency, for improving drilling rate without obvious effect, further, since bit life is limited, one
The effective coring round trip of drill bit is less, takes a significant amount of time make a trip coring and more bit change, and several hundred rice even a few km drilling rods return
Turning very big by the resistance of seawater, is finally applied to the power and torque very little of drill bit revolution, drilling efficiency is but still very low, when
Between higher cost.
