Description
Technical Field
The utility model relates to a rope coring probing construction technical field particularly, relates to a rope coring probing is gushed water pressure release drilling rod for drilling.
Background
The wireline coring drilling technique is a technique for taking out a core from a drill pipe without pulling out a drill string. The specific process is as follows: after the drill rod is connected with a rope coring drilling tool and a coring drill bit which are internally provided with a core tube, the drill rod is driven by the drill to rotate to drill, the core enters the core tube, and the core tube is fished out after the core tube is drilled to a certain depth, so that the core can be taken out. And after the core tube is put into the rope core drilling tool again to reach the preset position, the next drilling can be started. The process does not need to lift the drill rod out of the drill hole, so that the efficiency is high. However, when the drill encounters a water-bearing stratum during drilling and groundwater is flushed from the hole, the core barrel cannot be easily put into the drill pipe. According to practical experience, the probability of water inrush is high when horizontal and near-horizontal drilling holes are drilled, and when the water inrush amount and the water inrush pressure are high, the operation of putting the core barrel into the drill rod becomes very difficult. Because the outer diameter of the core tube is close to the inner diameter of the drill rod, the clearance between the core tube and the drill rod is very small, and in the operation process, an operator is continuously sprayed by water, a large amount of accumulated water exists in a construction site, and certain potential safety hazards exist. If the method of putting all the drill rods into the core barrel is adopted, the auxiliary time for pulling and putting the drill rods is greatly prolonged, and the construction efficiency is reduced. A common approach to this problem is to try to reduce the borehole water inflow and water inflow pressure.
An application with an authorization publication number of CN202970614U discloses a water inrush drilling water stopping device.

The patent application with the publication number of CN108868825A discloses a rapid drilling hole plugging method with high pressure and large water inrush quantity, which is suitable for plugging drilling hole water inrush. Patent application with publication number CN111764863A discloses a method for blocking high-pressure borehole water gushing of a fault fracture zone in a well, which uses a directional drilling technology in the well to block the high-pressure borehole water gushing of the fault fracture zone. The patent application with the publication number of CN112375549A discloses a weighted fiber slurry for water burst drilling, a preparation method and a drilling method. It utilizes this aggravate fibre mud to drill hole to carry out the timely switching of different mud according to actual mud return volume and mud return proportion at drilling process, make in the drilling condition that changes, can keep the pore wall firm all the time, avoid gushing water and the condition of loss to take place. The method focuses on blocking and suppressing water burst of the drill hole, the auxiliary time is long, the flow is multiple, the first three methods are generally used for non-coring drilling, and the fourth method is not suitable for horizontal and upward coring drilling.
Therefore, the utility model discloses an under the condition that does not influence the efficiency of construction, the design produces a drilling drainage utensil that gushes water to initial delivery of fisher or core barrel when being applicable to the drilling and gushing water, especially be applicable to the level, nearly the level gushes the application in the water drilling.
