Abstract
The invention discloses a pin-pulled broken-type automatic grouting valve floating valve. The automatic grouting valve floating valve is characterized in that one end of a supporting rod is connected with a valve cover pin hinge seat through a pin, and the other end is connected with a valve body pin hinge seat through another pin. The automatic grouting valve floating valve is simple in structure, and is easy to process, assemble and replace parts. As one end of the supporting rod is connected with the valve cover pin hinge seat through the pin, and the other end is connected with the valve body pin hinge seat through another pin, when a valve of the floating valve is in a half-open state, a fluid channel can be formed to realize the purpose of automatic grouting; and when the supporting rod is pulled and broken in a pumping circulation process, the valve can be automatically closed under the action of a spring to realize a function of a check valve.
Description
Technical field
The mode of manual grouting is taked in operation to the present invention relates to not stop lower brill (lower oil pipe) in brill (lower oil pipe) process under oil drilling, but automatic grouting.Namely play the effect of ball-and-seat after the turn on pump circulation, the generation of gas blowout accident in pipe in the time of can stopping to pull out of hole.
Background technology
bore the effect of only playing ball-and-seat in (lower oil pipe) process because of scene valve type float valve commonly used under oil drilling, and the restriction because of its bearing capacity and drilling rod (oil pipe) collapsoing strength, lower brill (lower oil pipe) is to prevent from easily causing when valve type float valve from causing losing efficacy because the pressure that bears is excessive in pipe even gas blowout accident of well kick during to certain well depth, anti-drilling rod (oil pipe) is squeezed to be ruined and causes the reason such as other complex accident, must stop lower brill (lower oil pipe) operation and pour into mud in drilling rod (oil pipe), to avoid the generation of above-mentioned many complexity and accident.In addition because of the existence of ball-and-seat, drilling rod (oil pipe) transfer in process for fear of the annular space that causes because of drilling rod (oil pipe) row of closing high return that speed causes that excessive surge pressure causes the complex situations such as leakage control drilling rod (oil pipe) lowering velocity.This has not only delayed a large amount of lower brills (lower oil pipe) time, has increased workman's labour intensity, and in the time of also might stopping tripping operation toward the interior mud grouting of drilling rod, because of the movable untimely differential sticking accident that causes of drilling rod, retarding oil gas is explored progress.
Summary of the invention
For the problems of the above-mentioned existence of on-the-spot valve type float valve, purpose of the present invention has aimed to provide and has not a kind ofly stopped that manual grouting is taked in lower brill (lower oil pipe) operation and the mode that realizes automatic grouting.Namely play the effect of ball-and-seat after the turn on pump circulation, prevent from managing the problem of interior well kick, gas blowout accident.
It is the spring force that has the principle balance autoshutdown valve type float valve valve of certain tensile strength to close according to support bar that this pin draws the principle of break-off type automatic grouting valve float valve, makes its valve be in half-open position, forms passage, realizes the purpose of automatic grouting.When finishing drilling turn on pump circulation time mud acts on power on valve greater than the tensile strength of support bar instantly, support bar is drawn, is fractureed.After termination of pumping, valve is in time closed the purpose that plays ball-and-seat under the effect of spring force, avoid existing with valve type float valve can not automatic grouting drawback.
The objective of the invention is to complete like this:
It is mainly to add valve cancelling nail hinge seat, pin, support bar, valve body pin hinge seat, pin composition on the basis of valve type float valve that pin draws break-off type automatic grouting valve float valve.
One of support bar is connected with pin with valve cancelling nail hinge seat, and the other end is connected with pin with valve body pin hinge seat.
The beneficial effect of advantage of the present invention and generation is:
1, the present invention is simple in structure, adopts conventional part assembling, is easy to processing.One of support bar is connected with pin with valve cancelling nail hinge seat, and the other end is connected with pin with valve body pin hinge seat.Make valve be in half-open position and form the fluid passage, reach the purpose of automatic grouting.When turn on pump circulation time support bar is drawn, fractures, valve is closed the effect of playing ball-and-seat voluntarily under the effect of spring.Reasonable and compact in structure, easy to use, and safe and reliable.
2, after field trial of the present invention success, not only do not stop lower brill (lower oil pipe) the operation operation of being in the milk when applying, also can accelerate drilling rod (oil pipe) lowering velocity.This not only can save a large amount of lower brills (lower oil pipe) time, also can avoid because stopping the lock of tool drilling of the movable untimely generation of tripping operation.
3, support bar of the present invention is the drillability material, if can not have any impact to drill bit during to the shaft bottom by bit port after being drawn, fractureing, saves drilling period, greatly reduces post workman's labour intensity, quickening oil-gas exploration progress.
Description of drawings
Fig. 1 is sectional view of the present invention.
The specific embodiment
As shown in Figure 1, to draw break-off type automatic grouting valve float valve be mainly to add valve cancelling nail hinge seat 1, pin 2, support bar 3, valve body pin hinge seat 4, pin 5 to form on the basis of valve type float valve to a kind of pin.
One of support bar 3 is connected with valve cancelling nail hinge seat 1 use pin 2, and the other end is connected with valve body pin hinge seat 4 use pins 5.Make valve be in half-open position and form the fluid passage, reach the purpose of automatic grouting.When turn on pump circulation time support bar 3 is drawn, fractures, valve is closed the effect of playing ball-and-seat voluntarily under the effect of spring.
Claims (1)
