Abstract
A hydraulic drill-pressure presser for directional drilling of sidetracked well, directional well and separate horizontal well comprises upper joint 1, cylinder body 2, O-shaped seal rings 3, a piston 4, a central spindle 5, connection joint 6 of the cylinder body, cap preparation 7 of transmission shaft, transmission sleeve 8 and transmission shaft 9, wherein the upper joint 1 and cylinder body 2, the cylinder body 2 and connection joint 6 of the cylinder body, the piston 4 and the central spindle 5, cap preparation 7 of transmission shaft and the transmission shaft 9, connection joint 6 of the cylinder body and the transmission sleeve 8 are all in threaded connection, the transmission shaft 9 and the transmission sleeve are in inner hexagon sliding fit, O-shaped seal rings are respectively positioned in the seal grooves of elements including the piston 4, connection joint 6 of the cylinder body, the cap preparation 7 of transmission shaft and the transmission shaft 9. The utility model has solved problems that bit feed is difficult to control, stability of weight on bit is difficult to maintain, and that false weight on bit is prone to occur etc. in current technologies, and can be widely used for directional drilling work of sidetracked wells, directional wells and separate horizontal wells.
Description
Technical field:
The utility model relates to hydraulic pressure the pressure of the drill pressurizer that a kind of sidetracked hole, directional well, separate well directional drilling are used.
Background technology:
In conventional drilling, the pressure of the drill is that drill bit top drill collar weight provides, though this conventional press mode is simple, also exists many inevitable disadvantages.For obtaining a metastable the pressure of the drill, in the conventional drilling, the pressure of the drill is provided by drill bit top drill collar weight, this conventional press mode, need driller's steering brake handle little by little, continuously to send brill, send the brill amount to be difficult for holding, the pressure of the drill also just is hard to keep stable.In sidetracked hole, directional well or horizontal well, owing to be subjected to the influence of factors such as partical gravity, buoyancy, frictional resistance, can produce " false the pressure of the drill " phenomenon, be difficult to obtain desirable the pressure of the drill, make operation have blindness, cause operate miss, cause all adverse consequences.
Summary of the invention:
The utility model purpose is to provide a kind of hydraulic pressure the pressure of the drill pressurizer, and it has solved the conventional press mode of utilizing that exists in the prior art need continuously send brill, send the brill amount to be difficult for holding, and it is stable that the pressure of the drill is difficult to keep; In sidetracked hole, directional well or horizontal well,, be difficult to obtain the problem of desirable the pressure of the drill owing to the influence that is subjected to factors such as partical gravity, buoyancy, frictional resistance produces " false the pressure of the drill " phenomenon.
The technical scheme that its technical problem that solves the utility model adopts is: hydraulic pressure the pressure of the drill pressurizer is equipped with cap, drive sleeve, power transmission shaft by top connection, cylinder body, O RunddichtringO, piston, axle, cylinder body jointing, power transmission shaft and forms; Top connection is equipped with cap with cylinder body jointing, piston with axle, power transmission shaft with cylinder body, cylinder body and is with drive sleeve and is threaded with power transmission shaft, cylinder body jointing, power transmission shaft and drive sleeve are that interior six sides are slidingly matched, and are equipped with in cap, each part seal groove of power transmission shaft at piston, cylinder body jointing, power transmission shaft and put into the O RunddichtringO respectively.Hydraulic pressure the pressure of the drill pressurizer is that the pressure drop that utilizes slurry flows to cross its following drilling tool (motor, drill bit etc.) acts on its piston and produces the pressure of the drill, if piston area is S, pressure drops to Δ P, then the pressure of the drill of hydraulic pressure the pressure of the drill pressurizer generation is F=Δ PS, therefore, the size that its produces the pressure of the drill is only fallen relevantly with the area of piston and pressure, and piston area is certain, can change pressure and fall Δ P and obtain suitable the pressure of the drill by adjusting drilling parameter.
The new beneficial effect of this practicality is, uses this device can make the pressure of the drill stable, helps improving rate of penetration and drilling tool application life; It can be converted to the pressure of the drill with bit nozzle or down-hole motor pressure drop; Extensional vibration and this drillstring vibrations more than pressurizer of drill bit can be separated, prevent extensional vibration, the protection drill string; Reduce the drill collar consumption, alleviate weight on hook and reduce waterpower consumption.
Description of drawings:
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model A-A sectional schematic diagram.
Among the figure, 1, top connection, 2, cylinder body, 3, the O RunddichtringO, 4, piston, 5, axle, 6, the cylinder body jointing, 7, power transmission shaft is equipped with cap, 8, drive sleeve, 9, power transmission shaft.
The specific embodiment:
As shown in Figure 1, this pressurizer is equipped with cap 7, drive sleeve 8, power transmission shaft 9 by top connection 1, cylinder body 2, O RunddichtringO 3, piston 4, axle 5, cylinder body jointing 6, power transmission shaft and forms; Top connection 1 and cylinder body 2, cylinder body 2 and cylinder body jointing 6, piston 4 and axle 5, power transmission shaft are equipped with cap 7 and are with drive sleeve 8 with power transmission shaft 9, cylinder body jointing 6 and are threaded, power transmission shaft 9 and drive sleeve 8 are slidingly matched for interior six sides, are equipped with in cap 7, power transmission shaft 9 each part seal groove at piston 4, cylinder body jointing 6, power transmission shaft and put into O RunddichtringO 3 respectively.
