In some embodiments, internal layer and skin are made up of elastomeric material.The program can realize the change of tube wall diameter, thus realizes the change of tube chamber volume.
In some embodiments, internal layer and skin are made up of corrosion resistant elastomeric material.Make coiled tubing have corrosion resistant characteristic by this set, this characteristic can ensure that coiled tubing is in acidifying, test, the security performance that can voltage-controlledly to operate etc. in completion practice.
In some embodiments, corrosion resistant elastomeric material is special-shaped polyurethane.This kind of material has good flexibility, retractility, the advantage such as high temperature resistant, high pressure resistant and corrosion-resistant, fully can ensure coiled tubing safety in use.
In some embodiments, enhancement layer comprises sub-supporting layer and covers the sub-topping outside sub-supporting layer, and sub-topping is fixed together with internal layer and skin respectively.Sub-supporting layer plays main supporting role in enhancement layer, and internal layer and the skin of sub-topping on the one hand for preventing sub-supporting layer from damaging tube wall, be conducive to enhancement layer on the other hand and be fixedly connected with outer field with internal layer.Preferably, sub-supporting layer is made up of braided steel wire.
Compared with prior art, coiled tubing of the present utility model is hollow cylindric under pressurized expansion state in pipe, and has the characteristic of conventional coiled tubing; Tabular can be reverted under normal pressure non-expansion state, its surface structure is similar to fire hose, there is the features such as good flexibility, retractility, high temperature resistant, high pressure resistant and corrosion resistance, the volume of its variable tube chamber makes it more be better than conventional coiled tubing, himself transport more convenient while the discharge capacity increasing coiled tubing.
Accompanying drawing explanation
Also will be described in more detail the utility model with reference to accompanying drawing based on embodiment hereinafter.Wherein:
Fig. 1 is the cross sectional representation according to coiled tubing of the present utility model.
In the accompanying drawings, identical parts use identical Reference numeral.Accompanying drawing is not according to the scale of reality.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Details described here is exemplary, and is only used for carrying out illustrative discussion to embodiment of the present utility model, and their existence is to provide the most useful and the most intelligible description be considered to principle of the present utility model and concept aspect.About this point, here do not attempt introduction CONSTRUCTED SPECIFICATION of the present utility model being exceeded to the degree needed for basic comprehension the utility model, those skilled in the art can be expressly understood by manual and accompanying drawing thereof and implement several form of the present utility model how in practice.
Fig. 1 shows the cross sectional representation of a kind of coiled tubing 100 provided according to the utility model.This coiled tubing 100 comprises body, the tube chamber 20 that body comprises tube wall and formed by tube wall, and wherein, tube wall has variable diameter and has variable volume to make tube chamber 20.The structure of tube wall can have a detailed description hereinafter.
The tube wall of coiled tubing 100 of the present utility model has variable diameter and tube chamber 20 can be made to have variable volume, when coiled tubing 100 in use, tube wall is subject to the pressure of oil body, and the volume of tube chamber 20 increases gradually, and this substantially increases the discharge capacity of coiled tubing 100; When coiled tubing 100 is finished using, in tube chamber 20, pressure and oil body fade away, the volume of tube chamber 20 reduces gradually, coiled tubing 100 forms tabular gradually, the coiled tubing 100 that volume reduces can reduce taking up room of coiled tubing 100, when transporting this coiled tubing 100, longer coiled tubing 100 can be held in same transport space, thus effectively saved cost of transportation.
