Specific embodiment
With reference to embodiment and Figure of description, claims hereof is done it is further specifically
It is bright, but do not form any restrictions to the utility model.
Embodiment 1
A kind of shut-in well resin plunger provided by the utility model includes the plunger body 1 of solid cylindrical, institute refering to Fig. 2
The diameter for stating plunger body 1 is gradually reduced from top to bottom, is conveniently placed at the position needed in well.Outside the plunger body 1
Columnar step 2 there are two setting in week, forms the first groove 5 between two columnar steps, when filling out envelope, is filled out in the first groove 5
Filled with cement, be conducive to fill out the cement being honored as a queen and combined with the borehole wall, increase whole fastness.
The lower face of the plunger body 1 and trapezoidal cylinder body 3 is located at same level, under the trapezoidal cylinder body 3
Bottom surface is identical with the floor space size of plunger body 1, not only improves and fills out envelope, also has and is processed convenient for resin plunger.
The 1 lower end periphery of plunger body is equipped with trapezoidal cylinder body 3, is conducive to resin plunger sinking down into needs and fill out
