The utility model is characterized in being provided with a lower part lifting guiding cylinder, a certain joint, the splined shaft, the shock bearing ring, the joint for discharging water, and the shock spreading ring which are respectively integrated, wherein, seal is arranged between the sleeve barrel of the lower part lifting guiding cylinder and the certain joint, and seal is arranged between the splined shaft and the joint for discharging water. Under the permitted pump volume, the utility model has the advantages of reduced pump pressure, improved impact energy, increased transmission efficiency of impact work for drilling, strong back pressure proof ability, and good sealing performance.
Description
The utility model relates to a kind of solid mineral reserve geological prospecting that is used for and reconnoitre the instrument that creeps in the hole, particularly be that a kind of wire line coring does not have spring impact rotating drilling tool.
Known wire line coring does not have the spring churn drilling tools and is made up of the outer pipe assembly and the inner tube assembly that contain splined shaft, hold shake ring.Inner tube assembly comprises the no spring valve formula double acting hydraulic impacter that contains float valve, float valve body, piston block stamp, center tap, choke valve, anvil block, place no spring valve formula double acting hydraulic impacter top the last axis of cone, main shaft, be contained in and carry the suspension positioning mechanism that draws sleeve, goes up the bullet card containing on the main shaft, place no spring valve formula double acting hydraulic impacter bottom contain with the splined shaft relative position on drainage joint, pass the single action mechanism that shake encircles.It is complicated so seal is many that this drilling tool part reaches the water route more, salvage, throw in very easily damage, not only success rate is low and be difficult to guarantee sealing effectiveness.This drilling tool movable part is many, and is strict to transmission of power medium one property of flush fluid, and when particularly using mud, to circulating system desanding performance requirement height, sand content is little; Little because of gap between the inner and outer pipes assembly, cause that back pressure is big, pump pressure is high, influence block stamp and hit the anvil ballistic work; After inner tube assembly was thrown in the location, the moving gap of string was big, reduced ballistic work and was unfavorable for the impactor working stability, and the movable members that transmits ballistic work is many, and quality is big, and transmission efficiency is poor, and capacity usage ratio is low; Rope gets that to creep into the pump amount little, and pump pressure height, flushing liquor leak two-tube more serious than common, are difficult for improving impact energy; It is big that rope is got bit wall thickness, and limited ballistic work is difficult for reaching volumetric fracture energy essential when causing the drill bit fractured rock, thereby difficulty is big.
In view of above reason, the purpose of this utility model is to allow to reduce pump pressure under the pump amount in order to provide a kind of, the transmission efficiency that improves impact energy and hit the anvil ballistic work, and anti-back pressure ability is strong, and the wire line coring of good seal performance does not have spring impact rotating drilling tool.
The utility model is achieved in that the utility model is not have on the spring impact rotating drilling tool improved at known wire line coring, it is characterized in that suspension positioning mechanism comprises that also following the carrying that is contained on the main shaft draw sleeve pipe, the pipe assembly up and down are carried drawing on the sleeve relative position outside given joint, under carry drawing sealing (14) arranged between sleeve and given joint, splined shaft is with to hold shake ring in aggregates, drainage joint and biography shake ring are an integral body, sealing (17) (referring to Fig. 1) is arranged between splined shaft and drainage joint, the utility model hangs interior pipe, the commutation of ballistic work transmission and flushing liquor, hermetically-sealed construction is integrated, reduce the moving gap of string of inner tube assembly effectively, adopt upper-lower seal to guarantee no spring impactor requisite " low-pressure area ", pass shake ring and drainage joint, hold the shake ring and be combined into an integral body with splined shaft, reduced and passed the shake part, strengthened and passed shake area (pass shake contact surface area and can be 1.54 square centimeters), reduced the transmission energy loss of ballistic work, the transmission efficiency that has improved impact energy and hit the anvil ballistic work, anti-back pressure ability is strong, good seal performance.
The YX sealing ring made from the polyurethane rubber material is adopted in above-mentioned sealing (14), the J type dust ring made from the polyurethane rubber material is adopted in sealing (17), sealing (14) is contained in down to carry draws on the sleeve, sealing (17) is contained in (referring to Fig. 2, Fig. 3) on the drainage joint, simplified hermetically-sealed construction, reduce sealing ring quantity, improved the reliability and the durability (because of having adopted big, the wear-resisting material of elasticity) of sealing, reduced non-cutting time significantly.
Above-mentioned sealing (14), sealing (17) also can adopt the metal/metal high accuracy to seal movingly.
On the main shaft of above-mentioned inner tube assembly with on the relative reverse position of last bullet card bullet card (referring to Fig. 1) is housed down, can make and throw in the backlash that puts in place and hit the device outer tube and accurately locate, prevent that the impactor string is moving, not only improved the operating efficiency of impactor, and do not start impactor when helping cleaning bottom of hole.
Choke valve stroke in the no spring valve formula double acting hydraulic impacter in the above-mentioned inner tube assembly is the 4.5-21 millimeter, and the stroke that stretches into anvil block is the 3-12 millimeter, the stroke of piston block stamp is the 6-25 millimeter, make relative motion and the block stamp motion good teamwork of choke valve in block stamp, improved and hit anvil effect and job stability.
Choke valve in the above-mentioned no spring valve formula double acting hydraulic impacter stretches between part in the anvil block and anvil block gapped (referring to Fig. 5), and to enter anvil block easy in the bottom during throttle valve movement, improved job stability.
Adopt the surperficial heat treated metal/metal high accuracy of process (referring to Fig. 4) movingly between float valve in the above-mentioned no spring valve formula double acting hydraulic impacter and float valve body, removed the sealing ring of original float valve low-pressure area, guaranteed sealing effectiveness.
Hammer groove (referring to Fig. 6, Fig. 7) is lifted in the piston block stamp of above-mentioned no spring valve formula double acting hydraulic impacter bottom, makes to hit anvil and become a contact by the face contact, has increased simultaneously that to lift the flat side of a hammer long-pending, has accelerated the backhaul of piston block stamp, has improved frequency of impact.
To hit the anvil ballistic work in order more effectively increasing, to have strengthened piston block stamp diameter, make the upper piston and the area ratio of lower piston be 1:1.4.
Between the center tap of above-mentioned no spring valve formula effect hydraulic impacter and piston block stamp YX sealing ring (referring to Fig. 4) is housed.
The utlity model has following advantage:
1, economic benefit height:
1), pure brill timeliness improves 10-203%,
2), footage per round trip length improves 12-63%;
3), core recovery percentage improves 1-39%, rock core is complete, quality is good, bit life improves 53-200%;
4), hole Dou little, reduce to 1 ° by general time per hundred meters 3 °;
5, few during secondary station, pure brill rate is flat a little more than general backwater;
2, technological performance:
1), under the normal condition, throw in the success rate that puts in place and reach 100%, fishing success ratio can reach 98%;
2), start easily, working stability, reliable in the hole, anti-back pressure and anti-rock dust ability are stronger;
3), drilling tool intensity is big, long service life, for example a cover drilling tool has crept into 521 meters and still can continue to use;
