Abstract
The utility model provides a fluid pressure pipe expanding truing and repairing tool for an oil-water well. The truing and repairing tool consists of an anchorage device, a fluid pressure driver unit and a valving tube expander. The lower part of the anchorage device is connected with the upper part of the fluid pressure driver unit. The lower part of the fluid pressure driver unit is connected with the upper part of the valving tube expander. The connection screw threads of the anchorage device, the fluid pressure driver unit and the valving tube expander are drill pipe screw threads. The fluid pressure driver unit has the function of pressurization and provides a large axial force, so the valving tube expander is pushed to generate a large radial force. As a result, big casings and casings with serious deformation can be trimmed. Because of all-hydraulic truing, no vibration is generated, so the well cementation of casing string is not damaged and the service life of the oil-water well is not affect. As a result, the truing and repairing tool has remarkable economic benefits.
Description
One, technical field
The utility model is the oilfield oil well workover tool, particularly a kind of oil water well hydraulic expanding tube reshaping and renovation tools.
Two, background technology
Existing casing swage method is the mechanical type shaping, the instrument that uses has pyriform expand tube, roller device and jarring reshaper, when putting tubing string, the gravity of tube post produces radial load resiles the sleeve pipe hole enlargement of distortion undergauge, because tubing string gravity is limited, can only be used for the small casing shaping, or to being out of shape not serious casing swage, the casing swage success rate is low, occur shaping tool easily and be deformed the stuck problem that causes engineering accident of well section, because vibration is too big, destroy casing cementing easily again, influence oil-water well application life.
Three, summary of the invention
The purpose of this utility model is the deficiency that overcomes existing shaping tool, designs a kind of oil water well hydraulic expanding tube reshaping and renovation tools, and hydraulic coupling is changed into mechanical force, produces the axial force bigger than tubing string gravity, to big sleeve pipe and the serious casing swage of distortion.
The purpose of this utility model is achieved in that by anchor, hydraulic driver, distinguish tube expander to be formed, and the anchor bottom connects with hydraulic driver top, and the hydraulic driver bottom connects with distinguish tube expander top.
It is drill rod thread that anchor, hydraulic driver, distinguish tube expander connect screw thread.
The beneficial effects of the utility model are: the fluid power pusher has pressurization, the axial force that provides is big, the radial load that promotes the generation of distinguish tube expander is big, thereby can and be out of shape the serious casing swage of shape to big sleeve pipe, owing to be all-hydraulic shaping, friction during shaping, can the well cementation of casing string not damaged, can not influence the application life of oil-water well, therefore, the utlity model has remarkable economic efficiency.
Four, description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Among the figure: the 1st, anchor, the 2nd, hydraulic driver, the 3rd, distinguish tube expander.Be that embodiment of the present utility model is made up of anchor 1, hydraulic driver 2, distinguish tube expander 3, anchor 1 bottom connects with hydraulic driver 2 tops, and hydraulic driver 2 bottoms connect with distinguish tube expander 3 tops.It is drill rod thread that anchor 1, hydraulic driver 2, distinguish tube expander 3 connect screw thread.
The effect of anchor 1 is to support shaping tubing string, the hydraulic counter force when bearing shaping.The on-the-spot commonly used drill rod thread in oil field is all adopted in the last lower contact of anchor, is convenient to and drilling rod connects, and the grappling body can plural serial stage, and more reliable firm support force is provided.
Fluid cylinder, plunger are arranged on the hydraulic driver 2, and effect is to produce downward end thrust, and according to the size of shaping power, can be installed in series multistage fluid cylinder, plunger produce the end thrust that needs.The on-the-spot drill rod thread commonly used in oil field is all adopted in the last lower contact of hydraulic driver, and linking intensity is big, the sealing hole.
The utility model continues to transfer after can putting pressure, and one-stop operation can be carried out shaping to the many places deformed casing, and the efficient height is saved workover cost greatly.
