Abstract
The utility model aims to provide a high-frequency percussion drilling tool, comprising a downhole drill motor (1), an output shaft (2), an upper rotary valve (3), a lower standing valve (4), a main body (5), and a spline shaft (6) and a lower adaptor (7). The output shaft (2) is the output shaft of the downhole drill motor (1). Connection between the output shaft (2) and the upper rotary valve (3), the lower standing valve (4) and the spline shaft (6), the downhole drill motor (1) and the main body, and the spline shaft (6) and the lower connector (7) are all thread connection. The upper rotary valve (3) and lower standing valve (4) are equipped with the axial through hole at the deviation position of the shaft. The appropriate lower position of the main body (5) is equipped with an internal polygon or a spline mechanism, and the outside of the spline shaft (6) and the main body coordinates mutually. The tool has the advantages of simple structure and long service life.
Description
Technical field
The utility model relates to a kind of downhole drill instrument that oil is used, and particularly a kind of dither percussion drilling tool belongs to drilling well downhole tool class.
Background technology
At present, the percussion drilling tool that use in domestic oil field all is when rotate with certain speed, by certain frequency drill bit is applied impact, makes its fractured rock, carries out compound broken rock, thus the raising bit speed.The operating principle of the percussion tool of domestic use is all as described in the ZL200420123128.0, percussion tool is to utilize the liquid vibration block stamp to move back and forth, block stamp high speed impact hammering block, drive drill bit and drill, because vibration, makes very easily damages such as the mechanism that promotes the block stamp motion such as guiding valve, spring, changement by realizations of moving repeatedly of block stamp high frequency, cause such drilling tool life-span very short, cause the instrument complexity, difficult processing, maintenance difficulty, the very difficult needs that really satisfy drilling well.In addition, present hydraulic impactor need overcome the bigger inertia of block stamp self with certain mass in course of action, cause energy that certain loss is arranged.
Summary of the invention
The utility model is to provide a kind of do not have complicated changement, spring, dither percussion drilling tool simple in structure.
A kind of dither percussion drilling tool mainly is made up of mud motor 1, output shaft 2, last rotary valve 3, following standing valve 4, body 5, splined shaft 6 and lower contact 7 etc.Wherein, output shaft 2 is the output shaft of mud motor 1, output shaft 2 and last rotary valve 3, be between standing valve 4 and splined shaft 6, mud motor 1 and body 5 and splined shaft 6 and the lower contact 7 and be threaded down, last rotary valve 3 all has axially extending bore with following standing valve 4 on the position of off-axis, there are an inner polygon or spline mechanism in the appropriate location, bottom of body 5, and splined shaft 6 outside inside with body 5 form and cooperatively interact.
The utility model is not because inside has the changement of spring, guiding valve, complexity etc., and therefore relatively simple for structure, tool life is long.
Description of drawings
Fig. 1 the utility model structural representation;
Fig. 2 the utility model A-A schematic cross-section.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described in detail.
A kind of dither percussion drilling tool mainly is made up of mud motor 1, output shaft 2, last rotary valve 3, following standing valve 4, body 5, splined shaft 6 and lower contact 7 etc.Wherein, output shaft 2 is the output shaft of mud motor 1, output shaft 2 and last rotary valve 3, be between standing valve 4 and splined shaft 6, mud motor 1 and body 5 and splined shaft 6 and the lower contact 7 and be threaded down, last rotary valve 3 all has axially extending bore with following standing valve 4 on the position of off-axis, there are an inner polygon or spline mechanism in the appropriate location, bottom of body 5, and splined shaft 6 forms with it and cooperatively interacts.
The utility model operating principle is as follows: this instrument is connected drill string bottom, is positioned on the drill bit.When instrument during down to the shaft bottom, the turn on pump circulation also applies certain the pressure of the drill, mud motor drives output shaft and the together rotation at a high speed of last rotary valve under the effect of drilling fluid, at this moment, eccentric axis hole between last rotary valve and the following standing valve then is in and aligns or depart from this two states, because this action is carried out repeatedly, thereby form continuous high-frequency pressure pulse, under the effect of this pressure pulse, following standing valve and splined shaft apply fluctuating load to drill bit, and under the effect of this load, help more realizing that drill bit breaks rock, thereby improve rate of penetration.
Claims (5)
