Abstract
The utility model relates to a high-intensity compound tube which comprises a tube body made of metal material. The high-intensity compound tube is characterized in that the middle part of the tube body is axially provided with a groove, and a high-intensity fiber layer is wound and bonded at the groove. The high-intensity compound tube has the following advantages: the mechanical property of the high-intensity compound tube such as pressure resistance and extrusion resistance can meet and even exceed the level of the original sleeve tube so that not only can the intensity performance requirement of the sleeve tube be ensured to meet operation need but also is the high-intensity compound tube easy to mill and cut; therefore, the operation time is saved, and the operation efficiency is improved. Moreover, the compound tube further has the advantages of convenience in operation, good safety and low cost.
Description
Technical field
Oil gas well mining technical field of the present invention particularly relates to a kind of multilateral well that is used for and bores the high-strength composite pipe that the completion process is used.
Background technology
Along with the large-scale development of oil gas field, there are a large amount of new wells or old well to need window sidetracking to improve output, the Multilateral Wells technology of Xing Qiing was the drilling well new technology that grows up after directional well, sidetracked hole, horizontal well technology especially in recent years.This technology increases drainage area by get out several Multilateral Wells in a main borehole, improves oil well output, reduces the oil reservoir development cost.After the branch well hole cementing operation finishes, be lowered to again that branch well hole and main borehole is overlapping this section tail pipe of packaged milling tool and directly overlap milling and slice off.Because the overlay segment material is a high strength steel oil gas casing, cover mills difficulty, and the time spent is longer, and operating efficiency is lower.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of easy to operate, to reduce operation low-cost and can improve cover and mill the high-strength composite pipe of efficient and safety.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
High-strength composite pipe comprises the body that metal material is made, and it is characterized in that: be shaped on groove on described body middle part is axial, be fixed with the high strength fibre layer at groove.
The present invention can also adopt following technical scheme:
Described groove twines and is bonded with the high strength fibre layer.
The high strength fibre layer that described groove twines bonding is the carbon fiber material.
The high strength fibre layer that described groove twines bonding is the glass fiber reinforced plastic material.
Described body two-port inwall all is shaped on standard spiral shell button.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, the high strength fibre layer that promptly has been fastened on body makes the resistance to compression of clad pipe, the anti-sleeve pipe that mechanical property is equal to even is higher than same level, intensity height such as squeeze.Because fibrage is easy to cutting than the sleeve pipe material, makes whole clad pipe not only can guarantee the casing strength performance requirement, satisfies the operation needs, cuts but also be easy to overlap milling, has saved the activity duration, has improved overall operation efficient.In addition, this clad pipe also has easy to operate, safety and reaches the low advantage of cost well.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, body; 2, high strength fibre layer; 3, standard spiral shell button.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment 1, sees also figure, and high-strength composite pipe comprises the body 1 that metal material is made, and is shaped on groove on described body middle part is axial, is fixed with high strength fibre layer 2 at groove.In the present embodiment, be bonded with high strength fibre layer 2 in the groove winding, the high strength fibre layer that described groove twines bonding is the carbon fiber material.For the stress that reduces composite material tube is concentrated, at body 1 groove cutting beginning place, fall 30 degree chamferings earlier, with carbon fiber wire with ± miter angle degree by the pipe crimping molding mode utilize epoxy resin directly bonding be wrapped on the body 1.All be shaped on mechanical property requirements standard spiral shell buttons 3 such as to satisfy tension at body two-port inwall.
Operating principle of the present invention is:
The tail pipe that at first the high-strength composite pipe bottom is directly connected branch well hole, the high-strength composite pipe top union tail device of slipping out of the hand, with tail pipe be lowered to fully put in place after, make this clad pipe be in a well and a main borehole overlay segment.After the well cementation of well is finished, when linking up main borehole, need the cover milling to cut main borehole and the clad pipe that props up the well overlay segment, because clad pipe adopts metal material and high tensile strength fibrous material to make, so not only being easy to overlap milling cuts, for the communication of main borehole brings great convenience, also can save the activity duration simultaneously, increased substantially operating efficiency.
