Description
Technical field
The present invention relates to a kind of down-hole equipment in field of oil development more particularly to a kind of composite impact drilling tools.
Background technology
In petroleum drilling engineering, the raising of rate of penetration is eternal target.Oil drilling mode is to pass through drilling rod at present
Drill bit rotation is driven, rock is sheared by drill bit, is impacted, realizes the broken of rock.Fragmented rock passes through drilling well
Liquid is carried out ground.Entire drilling process is that drill bit is pressed in rock upper end by the static pressure that drill string provides, and is passed by drill string
The torque drive drill bit rotation being delivered at drill bit, type of drive includes turntable, top is driven and mud motor provides.
Drill bit is a most important part in entire drilling process, is directly related to the efficiency of broken rock.PDC drill bit is current
Using the preferable drill bit of more, effect, broken rock is mainly realized by the shearing to rock.Influence PDC drill bit broken rock effect
The parameter of rate includes mainly bit pressure and torque, and bit pressure is to influence the major parameter of PDC drill bit cutting edge wedging rock depth, and eat
Enter the volume that depth can be understood as individual pen rock cutting, bit pressure is bigger, and the depth of cutting edge wedging rock is bigger, rate of penetration
It is higher；Torque is the parameter for influencing stock-removing efficiency, and torque is higher, and shearing force is bigger, and rock cutting is more smooth, drill bit rotation fluctuation
It is smaller.
It is generally acknowledged that PDC drill bit is suitble to stratum soft and softer in boring, be not suitable for the drilling of hardpan, with boring hard
When layer, it is susceptible to：1) the rotation fluctuation of drill bit is larger, and stick slip vibration is more serious；2) bit penetration is inadequate, power auger
Speed is relatively low.It is the reason of limitation PDC drill bit uses in hardpan above.
And at present when boring chance hardpan, rock bit or diamond bit are generally used, both drill bits are hard
In quality layer, main broken rock mode is the mode of impact and mill pressure, although both drill bits energy crushing hard stratum, breaks
Rock efficiency is not very high.
In order to improve the rate of penetration of hardpan, the use of PDC drill bit drilling is a kind of effective method, but needs simultaneously
It solves PDC drill bit and is boring the stick slip vibration and the inadequate both of these problems of depth of tooth penetration that the when of meeting hardpan occurs.
In order to solve the problems, such as that hardpan rate of penetration is low, some scholars propose and devise spin drilling tool, this kind of work
Tool is to increase axial impact on the basis of rotary drilling, and be transmitted at drill bit, and rock is realized by the way of impact
Volume broken rock, at present these tools can be divided into two major classes by operation principle：Valve type impactor and jet flow type shocker.Such work
Tool has been applied at the scene, there is certain speed-increasing effect, but some problems also occurs, includes mainly：1) ballistic work
Larger, field application requirement is not achieved in the service life of drill bit；2) use of the larger ballistic work to bottom drilling assembly (BHA)
Service life proposes challenge；3) it is unfavorable for the progress of deflecting work.
In order to inhibit the stick slip vibration of PDC drill bit, torsion impact device is had developed respectively both at home and abroad, and answered at the scene
With.The operation principle of the tool is that the torsional pulse of high-frequency reciprocating is provided at PDC drill bit, reduces the fluctuation of torque at drill bit.
Currently, the tool is applied at the scene, and using effect is preferable, but the tool is the effect for playing vibration damping, to hard
The raising of the rate of penetration of quality layer is limited.
The patent for entitled " composite impact drilling tool (the CN 204457422U) " that the present inventor has applied, axial direction
Impact is the jet stream of pulse to be formed by specific structure, and strike on shell, due to the rheological characteristic of fluid, generated punching
The finite energy that load is smaller, is transmitted at drill bit is hit, is not enough to generate direct broken rock, main function is vibrating drag reduction；Together
When the drilling tool axial impact and torsional pulse frequency it is different, two kinds of shock loadings respectively work, and efficiency of breaking rock is limited.This hair
The patent for entitled " composite impact drilling tool (CN103953281B) " that a person of good sense has applied, the composite impact in the patent are
Implemented by a cam mechanism, due to broken rock need ballistic work it is larger, cam mechanism be susceptible to abrasion it is more serious into
And there is the case where premature failure, seriously limit the onsite application of the tool.
Based on posed problems above, the present inventor relies on is engaged in experience and the practice of relevant industries for many years, in conjunction with spinning
The characteristics of drilling tool and torsion impact device, proposes to improve the rate of penetration of hardpan and devises a kind of composite impact brill
Well tool, to overcome the deficiencies of existing technologies.
