Specific embodiment
The technical solution of the utility model is further described below by specific embodiment.
As shown in Figure 1, a kind of under balance pressure drilling Operating Pressure machine, including rise single system 1, tubing string Rotable Control System and
O exterior sealing system rises and is equipped with tubing string rotation control system between single system 1 and the o exterior sealing system
System, the tubing string Rotable Control System include jacking system 2 and elevating rotary system 3, and jacking system 2 is arranged in lifting rotation system
The top of system 3, drilling rod described in 2 clamping of jacking system prevent from altering on the drilling rod, and elevating rotary system 3 is realized described in rotation decentralization
Drilling rod.
Rise single system 1 include provide original power winch 1.5, winch 1.5 by wirerope 1.3, fixed pulley 1.2 with
Hook is connected with hanging ring 1.4, and 1.4 lower part of hanging ring is equipped with tap, and the tap lower part connects the drilling rod, described another
One end connects high-pressure rubber pipe.
As shown in Fig. 2, jacking system 2 includes supporter 2.2,2.2 lower part two sides of supporter are equipped with lifting hydraulic cylinder 2.4,
It is equipped with anti-jack slips 2.3 among 2.2 lower part of supporter, promotion or carrying slips 2.1 are equipped among 2.2 top of supporter.
As shown in figure 3, elevating rotary system 3 include be set to 3.7 lower part two sides of supporter elevating control fluid cylinder 3.6,
It is arranged in the middle part of supporter 3.7 and is equipped with main rotation gear 3.4, close to main 3.4 top of rotation gear and lower section point on supporter 3.7
Slips 3.3 and anti-jack slips 3.5 She You not be promoted, hydraulic motor 3.1,3.1 lower part of hydraulic motor are additionally provided on supporter 3.7
It is engaged equipped with pinion gear 3.2 with main rotation gear 3.4.
As shown in figure 4, o exterior sealing system is two groups of ring-like preventers 6 being fixedly connected, counter balance pocket is formed, it is ring-like
The bottom of preventer 6 is connected with well head attachment 7.When a ring seal is only arranged, when box cupling crosses ring seal, high
It is very big by being damaged to preventer under pressure difference, when design is there are two ring-like blowout prevention, when crossing box cupling, two preventers and drilling rod it
Between beat balance pressure after, then box cupling is allowed to pass through, balance pressure is released after and passes through preventer above again.The counter balance pocket is by connecing
Mouth links together with high-pressure pump to provide high-pressure balancing liquid.
Working principle:
In going down process, jacking system 2, the carrying slips 2.1 on the top of elevating rotary system 3, promotion slips 3.3 are handed over
Temporary substitute is made, and such as allows anti-jack slips 2.3, anti-jack slips 3.5 to leave the conical surface on platform, they all do not work at this time, if allowed
Entire drill string weight is all loaded on elevating rotary system 3, and jacking system 2 does not undertake drill string weight, and elevating rotary system 3 is continuous
After ground rotation and drilling to lowermost position, allows the promotion of jacking system 2 or carrying slips 2.1 to work, undertake whole drill string weights
When amount, elevating rotary system 3 no longer undertakes drill string weight, it allows promotion slips 3.3 to carry after can rising to highest order at this time, rises
Drop system 2 can continue rotary drilling, and such drilling rod weight acts on the slips of working condition, and upper part plays single lifting system
System 1 is not by great power.In 3 decentralization process of elevating rotary system, hydraulic motor 3.1 works, and will pass through pinion gear 3.2
Gear wheel 3.4 is driven to rotate, rotary power is directly passed to drilling rod by slips, realizes rotary drilling.
When such as meeting top or needing to increase bit pressure, lower part anti-jack slips 2.3, anti-jack slips 3.5 can be worked alternatively, and work is former
Reason is same as above.
During drill pipe coupling is crossed lower part preventer 6 and is above mentioned, in counter balance pocket 5 plus with well in identical pressure, this
Sample drill pipe coupling, by lower part preventer 6, after pressure release, then by the ring-like preventer 4 in top, prevents in the case where no pressure difference
Well liquid or gas leakage, also extend the service life of ring seal.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
