Abstract
The utility model discloses a pitching device for oil drilling coring, and relates to the field of drilling coring of oil and natural gas. The pitching device for oil drilling coring achieves rapid pitching to a high-pressure pipeline on the ground during drilling coring. According to the technical scheme, the upper portion of a straight-cylinder-shaped ball storage tank is connected with a linear driving mechanism, the lower portion of the straight-cylinder-shaped ball storage tank is provided with a clamp spring, and the middle of the straight-cylinder-shaped ball storage tank is a steel ball placing area. The minimum clearance of the clamp spring is smaller than the external diameter of each steel ball. The pitching device for oil drilling coring is characterized in that due to the adoption of a clamp spring locking device, the purpose of pitching a plurality of steel balls after a set of devices are installed is achieved, a pitch plug does not need to be disassembled for multiple times, and the pitching device for oil drilling coring is simple and convenient to operate, simple in operation, and rapid in action. The pitching device for oil drilling coring can be widely applied to drilling coring a field where pitch balls need to be pitched to continuously to a drill water hole and relative fields.
Description
Technical field
The utility model relates to oil, the gas drilling field of coring, and especially a kind of oil drilling is cored and used ball-throwing apparatus.
Background technology
In the oil and gas exploration process, the operation of mechanical adding pressure type drilling and coring delivery need drop into 4 steel balls usually at interval in drilling tool, so that realize that the heart is cut in the machinery pressurization in the drilling and coring delivery, drilling tool can not handling arrive suitable position sometimes, can't dismantle drilling rod and carry out pitching.Traditional way has two kinds, and the one, dismantle plug from standpipe or swivel neck pipe and carry out pitching.Because the gooseneck position is higher, makes the operator have certain security risk; Drilling tool within a certain period of time can't be movable during dismantling and tighten plug, and this also may cause drilling failures such as bit freezing; Dismantle and tighten plug and hand-held tool need be taken to eminence, exist the high-altitude junk to hurt sb.'s feelings and the danger of the well that falls; Ball of every throwing all needs to repeat, unload the pitching plug one time.Another traditional way is a pitching plug to be installed, when needing pitching on the high pressure line of ground, at first need termination of pumping, put back to water, dismantle plug again, put into steel ball, tighten plug, shut low pressure valve, last turn on pump release, ball of every throwing all needs to come again aforesaid operations, mainly there is the problem of 3 aspects in this mode, the one, ball is told under the effect of mud outside sometimes, misses at all, and night work is all the more so; The 2nd, waste mud and time; The 3rd, be unfavorable for environmental protection and safety and increased operating personnel's work slight.Therefore, be necessary very much to research and develop a kind of simple in structure, be convenient to execute-in-place, can drop into the new tool of one or more steel balls according to the technological requirement gradation, to improve the technical level of pitching technology, reduce operating risk.
The utility model content
The purpose of this utility model be time-consuming at artificial pitching in the prior art, require great effort, exist problems such as safety, environmental protection risk, provide a kind of ball-throwing apparatus is connected on the ground drilling liquid high pressure line, the oil drilling of realization safe pitching is at any time cored and is used ball-throwing apparatus.
Oil drilling of the present utility model is cored and with ball-throwing apparatus is: the top, storage ball cabin of straight-tube shape connects straight line driving mechanism, and the bottom is provided with jump ring, and the middle part is the steel ball storage area; The minimum clearance at jump ring place is less than the external diameter of built-in steel ball.
Described straight line driving mechanism comprises leading screw or telescoping cylinder; Described jump ring is wire circlip or steel disc jump ring, and its distribution form comprises vertical distribution or cross direction profiles, and its quantity is the 1-5 piece.
Described telescoping cylinder comprises that hydraulic jack or pneumatic cylinder, linear electric motors driving cylinder are a kind of.
The outer end of described leading screw is provided with boosting-rod; The bottom in storage ball cabin is provided with the oily ninth of the ten Heavenly Stems; Be provided with sealing ring between described storage ball cabin and the leading screw.
Compared with prior art, the beneficial effects of the utility model are: 1, adopted the jump ring locking system, can once drop into a steel ball according to technological requirement, can realize that a covering device installs the back and drops into a plurality of steel balls by customer requirements.Only need rotating threaded shaft (perhaps driving telescoping cylinder) when 2, operating, simple to operate, be swift in motion, and need not repeatedly to dismantle the pitching plug, do not waste drilling fluid, avoided environment pollution, simplified the flow chart of traditional pitching greatly.3, this device is connected on the high pressure line of drilling fluid ground, can be during use in terrestrial operation, and the operation that need not to ascend a height improves greatly with respect to the traditional handicraft safety.4, device adopts oil to connect the ninth of the ten Heavenly Stems, conveniently is connected with the ground high pressure line.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Mark among the figure: 1. boosting-rod, 2. leading screw, 3. storage ball cabin, 4. sealing ring, 5. steel ball, 6. jump ring, 7. oil ninth of the ten Heavenly Stems.
The specific embodiment
Now the utility model will be further described in conjunction with specification drawings and specific embodiments.
Embodiment 1, and with reference to accompanying drawing 1, boosting-rod 1 is connected with leading screw 2, and leading screw 2 and storage ball cabin 3 are connected by threads of lead screw, and realize sealing by sealing ring 4.Steel ball 5 is " one " word arrangement in storage bottom, ball cabin, and steel ball is stopped by jump ring 6 bottom, can not free-falling.The device lower end is designed to have and is connected the oily ninth of the ten Heavenly Stems 7, realizes quick connection the with drilling well ground high pressure line.
Elder generation's termination of pumping in the time of need carrying out pitching, rotation boosting-rod 1 orders about leading screw 2, and to move downward the steel ball 5 that promotes in the storage ball cabin 3 descending, jump ring 6 is become big gradually by expanded inner diameter simultaneously, when jump ring 6 internal diameters reach steel ball size, steel ball enters the ground high pressure line, jump ring 6 returns to original size rapidly, and second steel ball is blocked again, and at this moment turn on pump can be sent first ball into drilling tool.Only need continue to repeat said process when needing pitching once more, steel ball just can be put in the drilling tool on request one at a time.
Embodiment 2, and the scheme that provides according to embodiment 1 is changed straight line driving mechanism and be hydraulic jack or pneumatic cylinder, the linear electric motors driving cylinder is a kind of, all can well realize above-mentioned purpose.
