And its method for blocking.
Background technology
When drill bit is to subterranean well, because drilling well is too deep, the geological condition of extreme is frequently encountered, such as solution cavity,
Crack is developed very much, subsurface rock is firmly crisp, the soil is porous, and these situations will cause drilling fluid and cement etc. in drilling process
A large amount of losses of slurries, it will produce the significant wastage of slurries and serious environmental pollution, cause substantial amounts of human and material resources, wealth
Power is lost, in some instances it may even be possible to cause a series of major accidents such as bit freezing, well slough and blowout.Therefore, during strengthening to wellbore construction
The closure processing of solution cavity is very urgent.
From the point of view of current solution cavity leakage stopping technology, mainly put into the perfect of loss circulation material, and from well head to shaft bottom
The things such as cement ball, rubble, coarse sand and straw branch, then add sealing agent.Such method solution cavity all right to geology can
To prove effective, but solution cavity and cellular solution cavity that can not be larger to volume ratio be blocked, often this mode high cost, effect
Rate is low, and the rapid hardening, environment friendly to loss circulation material require very high.When running into cellular porosity, loss circulation material is often
Seepage is serious, and most of loss circulation material ot-yet-hardeneds are to flow into subterranean fracture, and then impurely descend underground river, can be caused serious
Environmental pollution and the wasting of resources, considerably increase the time needed for drilling well, have a strong impact on the efficiency and cost of closure solution cavity, this is right
Closure solution cavity causes very big difficulty.Therefore traditional waterproofing can only be adapted to that solution cavity is smaller, solution cavity internal environment relatively
Used in the case of good.

Fallen out of drilling tool pipeline, until reaching sleeve inner；
Step S5, ultrasonic sensor is by by the triggering induced signal produced by wooden bead, and control system will make
Electromagnet one is stopped, so as to lose magnetism, the radial slider one adsorbed by electromagnet one will be by extended state
Spring one pulling force, so as to cause movement of the radial slider one from the set barrel dliameter heart to sleeve wall；Originally blocked by radial slider one
Longitudinal sliding block firmly is due to by gravity, it will decline along longitudinal sliding block track, the connecting plate that welds together, connecting pole,
Contiguous block will be with the decline of longitudinal sliding block and entirety is moved down；Due to the effect of hinge one, hinge two, driven rocking bar will
It can rotate, so as to trigger radial slider two to produce the movement from the set barrel dliameter heart to sleeve wall, until rubber stopper blocks drilling well
Liquid perforate；Wherein, the ratchet device being made up of ratchet and tooth bar is set at the two ends of radial slider two, due to sliding installed in radial direction
The effect of the ratchet at the two ends of block two, radial slider two will can only produce the movement from the set barrel dliameter heart to sleeve wall, and can not produce
From sleeve wall to the movement in set barrel dliameter heart direction；
Step S6, rubber stopper is blocked after drilling fluid opening, and ultrasonic sensor receives trigger signal, and overground system is from fluid injection
Three cement injections of mouth, cement flows into sleeve out of drilling tool pipeline, due to covering in the pipeline of reception pipe two without radial slider two,
Cement is poured into from the pipeline of reception pipe two, is flowed through reception pipe two, reception pipe three and reception pipe four, is finally poured into pouch；
Step S7, cement is poured into after pouch, and pouch will expand rapidly, and will be seated against the growth of solution cavity wall；
Step S8, when the cement according to obtained by quantitative calculating all injects pouch, pouch is to be expanded to solution cavity size, sensing
Device control system will send signal, and triggers circuit make it that electromagnet two is stopped, after electromagnet two loses magnetism, radial slider
Three by the spring two in extended state pulling force, so as to cause radial slider three to make the shifting from the set barrel dliameter heart to sleeve wall
Dynamic, the reception pipe three originally blocked by radial slider three by gravity due to that will be declined so that reception pipe three, reception pipe four,
Check valve and pouch are separated with sleeve, are fallen into solution cavity；Due to installing check valve in reception pipe four, cement is flowed into can not after pouch
Outflow；If solution cavity volume is excessive, drilling rod and sleeve are pulled out into ground, a sleeve is reinstalled, above action is repeated, will
Underground underground river inside solution cavity, basal crack are thoroughly blocked；
Step S9, drilling fluid is irrigated by liquid injection port one, and drilling tool, sleeve are rinsed, and is flowed out from reception pipe two, will be remained
Rinsed well in the cement of drilling tool and sleeve inner；
Step S10, the present apparatus is taken out from drilling well, when after the cement in pouch thoroughly solidification, solution cavity is successfully sealed
It is stifled, next step drilling well work can be carried out.
Further, the solution cavity is unilateral solution cavity or bilateral solution cavity.
Environmentally friendly bag type paste underground intake transformation device of the present invention is blocked to solution cavity, by from well
Mouth slow cement injection into the pouch in shaft bottom, until pouch fills up solution cavity, then the pouch for filling cement is put into solution cavity,
When carrying out further drilling well work in pouch when theing cement solidifies again.Due to there is pouch to load loss circulation material below sleeve,
Loss circulation material can obtain nearly absolutely utilizing, and so not only can quickly block solution cavity to prevent safety problem,
But also can effectively solve the problems such as the drilling fluid loss in the case of complicated solution cavity, cement leakage, to substantially increase solution cavity
The efficiency of plugging operation, reduces the cost of plugging operation.Can be in big solution cavity, leakage geological stratification and cellular solution cavity
Conjunction is used, and to the less demanding of loss circulation material, and present apparatus low cost of manufacture, easy to maintenance, environmental pollution are small, can replace passing
The leakage stopping technology of system.
In addition, the structure design of the closing device, and it is used in combination with sensory-control system so that the present invention
The characteristics of also there is simple in construction, favorable integrated operability, high working efficiency.
