Slickline Stuffing Box

Hydraulic Seal Head

Bottom Sheave Grease Injection seal head

Product Description

Slickline Stuffing Box is designed to pack-off all size of solid wireline up to 0.125",with safety and convenience.

It is lightweight, compact and simple to operate. Positioned at the uppermost point of the pressure control

equipment string. The Stuffing Box incorporates a blow-out plug to automatically shut-in the well pressure

in the event of the slickline breaking or being stripped from the rope socket.

Slickline Stuffing Box consists of a chamber which contains packing with an external adjustable nut. The

slickline passes through the packing and the nut is hydraulically tightened to the point where leakage around

the line, caused by well pressure, is reduced to a minimum. If required a manual packing nut can be supplied.

Replacing the sealing elements can meet different sizes cable to work.

Seal Control Head used for sealing the wellhead in time and promise safety of operation.

It can be controlled by manual as well as hydraulic. Replace the sealing elements can meet different sizes slickline to work.

2. Tool Catcher

Product Description

Hydraulic Tool Catcher is a safety device, which is installed between the seal head and the lubricator, it ismainly used for automatically grasping rope socket when tools are connected underground and are lifted to the top end of the lubricator, thereby effectively preventing cables from falling off the cable head or instruments drop in well when the cable is broken or the rope socket is impacted on the bottom end of the seal head because of the very fast pulling speed or over big pull force.

Hydraulic Tool Catcher,when release the rope socket , should use the hydraulic control system for pressurizing to lead the hydraulic force to push the piston in the tool catcher and the robotic gripper, the piston drives the robotic gripper which is opened, and then release the rope socket. The upper end connect the grease injection seal head choke flow tube directly,and the safety choke flow ball valve is designed on it, once the cable falling off or broken from the cable head accidentally, under the function of the high pressure flow or the airflow, the safety choke flow ball valve can plug the cable hole to choked flow and seal wellhead automatically.

2. Lubricator

Top sheave

Product Description

The Lightweight Lubricators enable the wireline tool string to be introduced or retrieved from a well bore under pressure. The lubricator can be used singly also can use multiply according to the requirement of the oilfield operation,but the seal control head always be assembled on the top of the lubricator. Single Lubricator is 0.8-3m, the number of lubricator and total length could be decided by operation. Titanium alloy Lubricator is much better quality and lightweight than normal steel materials.

The Lightweight Lubricators usually consists of four basic parts: a quick union collar, a male quick union, a lubricator tube, and a female quick union.

Product Features

--The pressure bearing part adopts high strength alloy steel,which has good corrosion resistance;

--When operated at the wellhead,the nonnut will be hung at the platform,so that the sealing cover can be exposed to the wellhead;

--There is a convex pipe body in the middle part of the nozzle body,which increases the stiffness of the nozzle and the rigidity of the blowout preventer when it is connected with the nozzle for too long.

5. Slickline Ram Bop

Compact Slickline Valve

Manual Control Ram BOP

Hydaulic Control Ram BOP

Top sheave Bottom Sheave Grease Injection seal head

The BOP is used for sealing the wellhead to prevent well blowout accidents in logging operation when there are accidents and there are cables in the well. The BOP has simple structure, convenient application and maintenance, small volume, light weight, high pressure bearing, hydraulic remote control and simple and reliable operation.

The BOP is mainly composed of main casing, and ram assembly piston, hydraulic cylinder, lead screw, end cap, hand wheel and other spare parts, which are moving in the main casing in opposite direction. When the well needs to be sealed, the hydraulic control and grease injection pressure control system is pressurized to push the piston, thereby leading the two ram bodies to move towards the center of the well bore, and well sealing can be achieved through the associative action of the front rubber sealing element and the top sealing rubber. The ram can be locked on the shut-in position through clockwise rotating the locking hand wheel. What be specially noticed is that before the well is opened, the locking hand wheel must be anticlockwise rotated, the hydraulic control system can be used for pressurizing after the hand wheel is totally receded to the initial position, the piston is hydraulically pushed to led the two rams to rearwards move, and then, the well can be opened. It should be guaranteed to open the full i.d. to prevent the instruments and the ram from colliding when the well is opened.

6.Crossover/ Wellhead Adapter

Bottom Sheave

The main function of the crossover is that it can connect the wellhead with the whole Pressure Control Equipment conveniently and tightly。The thread type can be machined following the API-6A Standard or client's request.
