Abstract
The utility model relates to an oil drilling auxiliary tool, in particular to a vibration acceleration tool used for drilling. The vibration acceleration tool used for drilling comprises a body, a vibration short circuit is connected with the lower end of the body, a power assembly is installed in the inner portion of the body, a pressure control switch is arranged at the lower end of the power assembly, a pressure adjusting cavity is arranged at the lower end of the pressure control switch, a power piston is arranged in the pressure adjusting cavity, and a return spring is sleeved outside the power piston. The vibration acceleration tool used for drilling achieves periodically high-frequency impacting on a rock and destroying cementation stress between rocks and stress of the rock, improves machinery drilling speed, overcomes shortage that rapid rock breaking can not be achieved only through impact energy of water power and grinding of a drill in the existing deep well hard foundation.
Description
Technical field:
The utility model relates to a kind of oil drilling aid, and particularly a kind of drilling well is with vibrating the acceleration instrument.
Background technology:
At present, in the oil drilling field, in deep layer, hard formation oil drilling, how target is crept in fast and safely realization, has become the stern challenge that each large oil drilling enterprise faces.Deep well hard formation is because the compaction on stratum is high, and the formation lithology drillability is strong, and only the grinding with hydraulic blow energy and drill bit can't realize breaking fast the purpose of rock.
The utility model content:
The technical problems to be solved in the utility model is to provide a kind of drilling well with vibrating the acceleration instrument, and this instrument has been realized periodically rock being produced high-frequency percussion, and between the destruction rock, the stress of cementing stress and rock itself, improve rate of penetration.Overcome existing deep well hard formation and only can't realize breaking fast the deficiency of rock with the grinding of hydraulic blow energy and drill bit.
Technical solution adopted in the utility model is: a kind of drilling well comprises body with vibration acceleration instrument; The body lower end connects the vibration short circuit, and body interior is equipped with power assembly, and the power assembly lower end is equipped with pressure control switch, and the pressure control switch lower end is provided with pressure regulating cavity, and power piston is installed in pressure regulating cavity, and power piston is set with returning spring outward.
The beneficial effects of the utility model are: the utility model is installed the mode of power assembly owing to having adopted, thereby has the function that periodically rock is produced high-frequency percussion, and between the destruction rock, the stress of cementing stress and rock itself, improve rate of penetration.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of drilling well comprises body 1 with vibration acceleration instrument; Body 1 lower end connects vibration short circuit 7, body 1 inside is equipped with power assembly 2, and power assembly 2 lower ends are equipped with pressure control switch 3, and pressure control switch 3 lower ends are provided with pressure regulating cavity 4, power piston 6 is installed, the outer returning spring 5 that is set with of power piston 6 in pressure regulating cavity 4.
The utility model body 1 intensity is high, and vibration short circuit 7 bottoms are connected with drill bit, and body 1 top connection drilling tool connects easy, safe and reliable.Power assembly 2 drives rotation by drilling fluid, driving pressure control switch 3 rotates, in the interior generation pressure oscillation of pressure regulating cavity 4, the variation of pressure produces axial driving force to power piston 6, act on vibration short circuit 7, and then act on drill bit, and producing restoring force afterwards under the effect of returning spring 5, the utility model produces the vibration of certain amplitude and frequency under the effect of periodicity active force.The utility model relies on the work of the hydraulic energy control tool of drilling fluid fully, can and impact the installation parameter that amplitude is adjusted instrument according to the frequency of concrete needs, ground is easy to adjust, quick, by use the utility model can be effectively in conjunction with cutting energy and the impact capacity of hydraulic energy, drill bit, the compound action power of formation to bottom rock, improve efficiency of breaking rock, and then improve rate of penetration.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
