Description
Technical field
A kind of deep hole inner pipe full-automatic alarm cord coring drill in place is the utility model is related to, with being particularly suitable for use in deep hole
Matter core drilling.
Background technology
With rapid development of economy, the consumption of the energy is also growing, the conventional energy resource such as shallow oil, coal and natural gas
A large amount of consumption, from the point of view of its remaining reserves, the conventional shallow-layer energy can not continue long term support modern industry, therefore each national capital
Try to explore Hydrocarbon Resource of The Deep Formation.The energy is stored with geological core drilling wire line coring method to layer deeper to explore
Just become particularly important.
In application wire line coring technology carries out drilling process, can accurately judging inner tube assembly, whether this be rope in place
Ask for the key of core success.Probing is it was verified that inner tube can hear sound in place when more than 1500 meters, more than 1500
Meter Yi Hou, judge whether inner tube is very difficult in place.In drilling process, when inner tube in place after inner tube on hanging ring and outer tube
On seat ring contact block mud path, the blasthole that mud enters in inner tube, sent from apopore, so as to be formed inside drilling rod
Mud path.In place to realize that inner tube is alarmed in place, i.e., alarm mechanism changes pump pressure by inner tube to current inner tube afterwards in place
Valve is set to block up between blasthole and apopore, mud is pushed up, valve opening is stifled to be discharged from apopore, mud during this
The pressure rise of stock pump.This mechanism must be always maintained at elevated pressures after mud top valve opening is stifled and is always maintained at ensureing that valve is stifled
Open, can so increase the pump pressure in drilling process, there is very big infringement to pump, therefore the Opening pressure that valve blocks up can not be too big,
And in deep drilling pump pressure change it is too small do not observe, so be not suitable for deep borehole wire-line coring probing.
The content of the invention
The purpose of this utility model is aiming at above-mentioned the deficiencies in the prior art, there is provided a kind of simple in construction, action is easily
Realize, automatically realize process, the deep hole inner pipe relatively low to pump requirement full-automatic alarm cord coring drill in place of notifying in place.

Connection, the second torsion spring keep the second bullet card open, disc spring bottom by the second bullet card recovery tube provide on push up power, when inner tube in place
Afterwards, hanging ring and seat ring contact, mud peripheral passage block, and mud raises into blasthole mud pressure and pushes up valve opening core, valve
Core ribbon moves the second bullet card and comes downwards to the second adapter coupling bottom, and the second bullet card, which opens, is stuck in the second adapter coupling bottom, valve element without
Method return, slurry channel are opened, and mud pressure is returned to normal value, because the upper top effect of disc spring keeps the second adapter coupling
Do not move down.Second bullet card recovery tube is enclosed on the bottom of valve element, and catcher is connected by screw thread in the second bullet card recovery tube bottom and first
Connect, rock core fills basket after probing terminates, and basket is driven by upper top power is about to the second bullet card on the second bullet card recovery tube
Two play cards closure, the second bullet card is returned to the second bullet card recovery tube top.Valve element is up to block slurry channel, and pump pressure is again
Secondary rise proves that rock core has been filled with basket or there occurs rock core blocking phenomenon.
Clutch shaft bearing is fixed by upper bearing and step fixing seal, second bearing by step and spring, spring
Upper end is supported by second bearing, and lower end is supported by round nut, and catcher is connected through a screw thread in round nut and first, and safety pin passes through
Round nut ensures that round nut does not loosen with the first inscribed hole on hand, and catcher is connected through a screw thread in step and second, oil
Cup is connected by catcher in screw thread and second, and catcher is connected through a screw thread with non-return valve seat in second, and non-return steel ball is by itself weight
Power is seated on the valve port of non-return valve seat, and the two is quiet contact, and non-return valve seat is connected by screw thread with basket, basket and card
Spring abutment is connected through a screw thread, and jump ring is seated on clip spring seat lower taper inwall, and 2-3 millimeters are kept between clip spring seat bottom and drill bit
Gap.
First adapter coupling is connected through a screw thread with bullet card room, and bullet card room is connected by screw thread with the first reamer, and first
Reamer is connected through a screw thread with outer catcher, and outer catcher is connected by screw thread with the second reamer, and the second reamer passes through screw thread
It is connected with drill bit.
The beneficial effects of the utility model：
The utility model is notified in place by providing a mud pressure peak value to realize, and you will press after realization is notified
Power returns to normal value, and the infringement to slush pump is smaller, while reduces the performance requirement to pump itself, improves the use of pump
Life-span, it is not necessary to which pump keeps high pressure in drilling process, therefore does not produce harmful effect to drilling.Because valve gets lodged in opening
After will not return, valve block up spring pretightning force can be set higher value, such larger pressure peak deep borehole wire-line coring drill
During when and can be easily detected, therefore can realize that inner tube is alarmed in place in deep well drilling, after drilling and borrowing beam, rock
The heart fill basket inner tube assembly bear push up power valve element is pressed on valve seat, mud path blocks, slush pump pressure rise
Prove that rock core has been filled with basket, while the second bullet card is retracted, and can directly be carried out next time after proposing inner tube and removal of core
Probing, so as to reduce drilling non-cutting time.
