Abstract
The utility model discloses a slope section one trip drilling tool structure, including the PDC drill bit that connects gradually, take the single curved screw rod of centralizer, no magnetism drill collar, 10-15 of thick wall drilling rod, drilling rod 25-50 and two 30-35 of thick wall drilling rod. The utility model discloses apart from 200 supple with material 260m before the target, survey horizontal well in the cancellation, realize that inclined shaft section one trip is bored, the utility model discloses reducible tripping drilling number of times shortens well drilling cycle, reduces the construction risk.
Description
Technical field
The utility model relates to the rich property brill way-type drilling unit structure of a kind of suitable oil well horizontal well drilling operation, is fit to the drilling tool structure that oil well horizontal well drilling operation lower curved section bores for a time.
Background technology
Carry out the oil well horizontal well construction in the prior art, through development in a few years, the oil well horizontal well drilling technology has obtained very great development, carry out in the prior art in the oil well horizontal well construction equipment, casing programme is that Ф 222.2PDC drill bit two spuds in to kickoff point (KOP), trip-out is changed Ф 215.9 rock bit deflectings and is crept into the 215.9mm rock bit when the angle buildup interval drill bit is deflecting during deflecting.Long celebrating oilfield horizontal well does not bore and leads eye at present, is drilled into about oil reservoir vertical depth 50m, and reference lamina is logged well after occurring midway.
But oil reservoir is stablized block relatively at present, surveys in the cancellation, and brill of lower curved section can directly be drilled into into window, and apart from 200-260m, adopt and bore technology twice before the target, the drilling tool rate of increase of angle does not reach designing requirement, can not realize, use rock bit, be subjected to the restriction of bit life, make a trip number of times more than three times, be unfavorable for speed-raising, drilling period is longer, changes the screw rod camber, improve PDC drill bit rate of increase of angle, be the main direction of speed-raising.
Summary of the invention
For solving above-mentioned existing in prior technology technical problem, the utility model proposes a kind of lower curved section and bore a drilling tool structure, for before the target apart from 200-260m, survey horizontal well in the cancellation, realize that lower curved section bores for one time, the utility model can reduce the number of times that makes a trip, and shortens drilling period, reduces construction risk.
The utility model is realized by adopting following technical proposals:
A kind of lower curved section bores drilling tool structure one time, it is characterized in that: comprise the PDC drill bit that connects successively, the curved screw rod of list, non magnetic drill collar, heavy wall drill pipe one 10-15 root, drilling rod 25-50 root and the heavy wall drill pipe two 30-35 roots of band centralizer.
Described PDC drill bit is that Ф 216mm protects footpath PDC drill bit by force.
The curved screw rod of described list is the curved screw rod of list of 213mm for the centralizer external diameter.
The diameter of described non magnetic drill collar is Ф 165mm, built-in wireless drilling inclinometers device.
The diameter of described heavy wall drill pipe one, drilling rod and heavy wall drill pipe two is Ф 127mm.
Compared with prior art, the beneficial effect that reaches of the utility model is as follows:
1, in the utility model, adopt the PDC drill bit that connects successively, the list of band centralizer to bend the drilling tool structure that screw rod, non magnetic drill collar, heavy wall drill pipe one 10-15 root, drilling rod 25-50 root and heavy wall drill pipe two 30-35 roots form, it is preceding apart from 200-260m to solve target, survey the horizontal well lower curved section drilling process number of times that makes a trip in the cancellation, do not use this technical level well to reduce brill at least 2 times, thereby shorten the oil well horizontal well drilling cycle, improve bit speed, simplify the horizontal well construction process.
2, heavy wall drill pipe specifically adopts the 10-15 root, drilling rod 25-50 root and heavy wall drill pipe two 30-35 roots, and protect footpath PDC drill bit in conjunction with the PDC drill bit by force for selecting Ф 216mm for use, it is the curved screw rod of list of 213mm that single curved screw rod is selected the centralizer external diameter for use, it is Ф 165mm that non magnetic drill collar is selected diameter for use, the non magnetic drill collar of built-in wireless drilling inclinometers device, the heavy wall drill pipe of selecting for use one, the diameter of drilling rod and heavy wall drill pipe two is Ф 127mm, the drilling tool structure that forms has best result of use, can reduce because occurring drill bit failures in the drilling process, shorten drilling period, need the horizontal well advantageous particularly of kill-job for the high pressure block, because of the minimizing number of times that makes a trip, the spy enters target zone fully and does not pull out of hole midway, reduce the accidents such as overflow blowout that make a trip and bring out, because of without rock bit, complex situations such as lost cone can not occur.
Description of drawings
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments, wherein:
Fig. 1 is the structural representation of this use habit
Mark among the figure:
1, PDC drill bit, 2, single curved screw rod, 3, non magnetic drill collar, 4, heavy wall screw rod one, 5, drilling rod, 6, heavy wall drill pipe two.
The specific embodiment
As preferred forms of the present utility model, referring to Figure of description 1, the utility model discloses a kind of lower curved section and bore a drilling tool structure, comprise the PDC drill bit 1 that connects successively, the curved screw rod 2 of list, non magnetic drill collar 3, heavy wall drill pipe one 410-15 root, drilling rod 25-50 root and the heavy wall drill pipe two 630-35 roots of band centralizer.
In actual use, the lower curved section drilling tool structure is as follows:
It is the single curved screw rod 2 (button-type 430 * 430 or 430 * 460) of 213mm+joint+MWD joint+1 (interior placement wireless drilling inclinometers device+)+Ф 127mm heavy wall drill pipe 10-15 of the no Ci Zuan of Ф 165mm Collars root+Ф 127mm drilling rod 25-50 root+Ф 127mm heavy wall drill pipe 30-35 root that Ф 216mm protects seven 1.5 ° of centralizer external diameters of footpath PDC drill bit 1+ by force.
In the oil well horizontal well construction, length according to distance before the target, determine preferred casing programme and drill bit, grow 6 target zones than good ground for Hua Qing, Ansai, distance before the target is cancelled the horizontal well of electrical measurement midway less than 260, and rate of increase of angle is greater than the horizontal well of 18 °/100m, use Ф 216mm to protect drill bit+7LZ172mm*1.5 ° of * 213mm of footpath PDC centralizer by force, realize that lower curved section bores for one time.
Drill bit is preferably particularly important.The at present preferred drill bit Ф 216EDM1616SEL of horizontal segment or Ф 216SM1665SSR drill bit.
