Summary of the invention
The purpose of the utility model provides the flexible lubricator of a kind of external hanging type; Adopt the telescoping cylinder hermetically-sealed construction; Have in airtight space and still can make the characteristics of putting forward on the down-hole string instrument; Smoothly farm labourer's tool in the well is tripped out or transfers in the time of can in well, having high pressure, and then make the also salable farm labourer's of the removing tool of the Operating Pressure equipment that does not contain lubricator, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
The described external hanging type of the utility model lubricator that stretches comprises lifting sub, center-pole, hydraulic cylinder oil-in, hydraulic cylinder, hydraulic cylinder oil return opening, hydraulic cylinder piston, prolongation cylinder, pressure relief opening, abutted flange, Hydraulic anchor, hydraulic cylinder cylinder cap, box cupling.Said lifting sub is connected with abutted flange with hydraulic cylinder, box cupling, prolongation cylinder in order; Hydraulic cylinder is equipped with hydraulic cylinder in the lower end, and hydraulic cylinder piston is installed in the hydraulic cylinder, and hydraulic cylinder piston passes from hydraulic cylinder; The hydraulic cylinder piston lower end is equipped with Hydraulic anchor; Hydraulic cylinder oil-in, hydraulic cylinder oil return opening are installed on the hydraulic cylinder, on the prolongation cylinder pressure relief opening are installed, center-pole is installed in hydraulic cylinder and the lifting sub.
Wherein, said lifting sub is up-small and down-big variable-diameter structure, and its top is provided with side opening.Said center-pole one end matches with the hydraulic cylinder piston upper end, and the other end stretches out outside the side opening of lifting sub.Said abutted flange is installed on the bottom that prolongs cylinder.Said hydraulic cylinder piston upper end is in hydraulic cylinder, and hydraulic cylinder and abutted flange are passed in the lower end.Said Hydraulic anchor is installed on and stretches out on the outer hydraulic cylinder piston of abutted flange.Said hydraulic cylinder top is equipped with the hydraulic cylinder oil-in, and the middle part is equipped with the hydraulic cylinder oil return opening, and the bottom is equipped with pressure relief opening.Said hydraulic cylinder is monolithic or the split-type structural that is connected by box cupling, and hydraulic cylinder is a upper end closed formula member, and its center, upper end is provided with the hole of passing center-pole.Said hydraulic cylinder piston is " T " shape structure, and the top of being somebody's turn to do " T " shape structure is on the top end face of hydraulic cylinder cylinder cap, and the center is provided with through hole.Said center-pole is the hollow cavity structure, and its hollow cavity is connected with the central through hole of hydraulic cylinder piston.
The present invention compared with prior art has following advantage:
1, external hanging type stretches, and lubricator is removable to be adorned, and easy construction has improved efficiency of construction;
2, make and do not have the Operating Pressure of lubricator equipment to seal to remove farm labourer's tool;
3, abutted flange makes the flexible lubricator of external hanging type be connected with Operating Pressure equipment, forms the integral body of a sealing, the instrument coupling part can make the flexible lubricator of external hanging type quickly and easily with well in instrument be connected, bear the interior tubing string weight of well simultaneously.
