Abstract
The utility model relates to an automatic steel ball throwing device for a water hole of a drilling tool. The automatic steel ball throwing device mainly comprises nine components, namely a main body, a piston assembly, a piston baffle plate, a piston locking screw, a piston limit screw, a spring, a sealing ring, a steel ball and a ball retaining sleeve, wherein the main body is used for accommodating the steel ball, the ball retaining sleeve is used for fixing the steel ball, the piston assembly is used for locking the ball retaining sleeve, the piston locking screw is used for mechanically locking the piston assembly, and the steel ball is limited through the main body, the ball retaining sleeve, the piston assembly and the piston locking screw when the steel ball is not required to be thrown, however, the circulation of drilling fluid is not affected; and the piston locking screw is disassembled in the working procedure before ball throwing, and the steel ball is automatically thrown into the water hole of the drilling tool through the operation of termination of pumping. The automatic steel ball throwing device for the water hole of the drilling tool can be used for automatically throwing the steel ball through the operation of termination of pumping, is time-saving and labor-saving, secure and reliable, can realize the continuous operation and is particularly suitable for coring construction.
Description
Technical field
The utility model is a kind of drilling tool hydrophthalmia automatic ball-throwing apparatus when being used for oil, gas drilling coring operation or other operation.
Background technology
In oil, the natural gas exploration process, drilling and coring delivery construction operation or other (windowing, descend tail pipe etc.) operation, need in the drilling tool hydrophthalmia, throw steel ball, so that realize the pressure of spraining of cutting the heart or other operation of drilling and coring delivery, sometimes drilling tool can not be mentioned, and need unload plug from standpipe or water tap (drive on the top) and manually throw.During the artificial operation cost of throwing steel ball, effort, and the motionless within a certain period of time risk that has bit freezing of drilling tool.
Summary of the invention
Artificial throwing steel ball is time-consuming in order to overcome, effort and have the problem of bit freezing risk, and a kind of drilling tool hydrophthalmia automatic ball-throwing apparatus only utilizes the termination of pumping operation just can automatically steel ball be dropped into the drilling tool hydrophthalmia, shortens the pitching time to greatest extent, guarantees the continuity of constructing.Purpose of the present invention is exactly to provide quick and easy a kind of drilling tool hydrophthalmia automatic ball-throwing apparatus for oilfield construction.
The design scheme that a kind of drilling tool hydrophthalmia automatic ball-throwing apparatus is adopted is: the present invention is made up of body, steel ball, spring, sealing ring, the cover of blocking, piston assembly, piston baffle, the spacing screw rod of piston, nine parts of plunger lock screw rod.Body is processed with gas thread for the cylindrical shape two ends, and radially tube wall is processed with the profiled holes of cylindrical inner cone, communicates with the body centre bore, and bellmouth is partly installed piston assembly, and circular portion is threaded with piston baffle; The cover of blocking is installed on body interior, and is spacing by the pin of piston assembly end transverse slat.Blocking, it is cylindric to overlap into, and the side, upper end processes a circular hole, and its opposite flank processes a groove groove, and circular hole is connected with the pin of piston assembly.It is conical that piston assembly one end is, and conical portion is installed sealing ring, and the other end is cylindrical, and the transverse slat of cylinder end face is equipped with pin, and circular hole is processed at piston assembly tapering part center, and spring is installed in the circular hole.It is cylindric that piston baffle is, cylindrical processing regular screw threads, and the center processes waney hole, and circular hole, spring that the spacing screw rod of piston passes piston baffle are connected with the method for piston assembly with screw thread, and the plunger lock screw rod is connected with the spacing screw rod of piston threadably.
The utility model has the advantages that: compact conformation, easy to operate, safe and reliable.This physical efficiency is connected with drilling rod, according in good time being connected on the drilling rod of technological requirement; Seal fluid power helps envelope, can bear high pressure; Plunger lock screw rod mechanism lock piston assembly, no matter turn on pump or termination of pumping, piston assembly can not be moved and steel ball is spacing, but does not influence the circulation of drilling fluid; Lay down the plunger lock screw rod after turn on pump is normal, piston assembly drops into steel ball the drilling tool hydrophthalmia by the turn on pump state automatically to the termination of pumping state, turn on pump once more behind the steel ball input drilling tool.The pitching operation can realize the continuity of operation, and the construction that is particularly suitable for coring is used.

A kind of drilling tool hydrophthalmia of Fig. 1 automatic ball-throwing apparatus schematic diagram:
1. body 2. piston assemblies 3. piston baffles
4. spacing screw rod 6. springs of plunger lock screw rod 5. pistons
7. sealing ring 8. steel balls 9. cover of blocking
The specific embodiment
According to Fig. 1 the utility model is further described.
A kind of drilling tool hydrophthalmia automatic ball-throwing apparatus is made up of body 1, piston assembly 2, piston baffle 3, plunger lock screw rod 4, the spacing screw rod 5 of piston, spring 6, sealing ring 7, steel ball 8, cover 9 nine parts of blocking.
Body 1 two ends can be connected with drill rod thread, are connected on the drilling tool behind the following intact column.The internal diameter of body 1 holds steel ball 8, cover 9 stationary balls 8 of blocking, and piston assembly 2 lockings are blocked and are overlapped 9, and the 4 mechanical caging piston assemblies 2 of plunger lock screw rod are spacing with steel ball 8 when not needing pitching; Plunger lock screw rod 4 can make piston assembly 2 turn on pumps or termination of pumping can not move at this moment.When shedding plunger lock screw rod 4, the pressure of piston assembly 2 inside and outside the drilling tool hydrophthalmia that bears under the turn on pump state is greater than the active force of spring 6, and this makes a concerted effort to make piston assembly 2 cover 9 lockings of will blocking; During the termination of pumping operation, pressure in the drilling tool hydrophthalmia reduces, drilling fluid fluid pressure in the drilling tool hydrophthalmia that the active force of spring 6 bears greater than piston assembly 2, the active force of spring 6 overcomes drilling fluid fluid pressure promotion piston assembly 2 and moves a certain distance to drilling tool hydrophthalmia center, piston assembly 2 will be blocked and be overlapped 9 releases, the cover 9 of blocking moves down under action of gravity, and steel ball 8 enters the drilling tool hydrophthalmia under action of gravity, realizes throwing motion.Turn on pump piston assembly 2 sets back under the promotion of drilling liquid pressure once more, and fluid pressure promotes piston assembly sealing drilling fluid.
