ABSTRACT:
BACKGROUND OF INVENTION
1. Field of Invention
The present invention relates to down hole tubing for wells. More particularly, but not by way of limitation, the invention relates to flexible hose well suited for deep well fluid and gas recovery applications.
2. Related Art
In most wells, rigid metal tubing is employed to carry fluids and gas out of the well. The metal tubing is very costly to transport and install, but needed in order to withstand the forces of gravity exerted on the tubing when installed at relatively large depths, i.e. thousands of feet below the surface. Although alternative conduit material exists which is relatively far less expensive, such conduit has not been employed for various structural limitations. For example, flexible synthetic hose is prone to bottle necking when installed at deep depths due to the weight load overcoming the elasticity factors of the hose.
Accordingly, there remains a need to improve conduit used in extracting fluids from wells. The present invention solves the described problems which exist with respect to such conduits and methods of installing the same.
SUMMARY OF THE INVENTION
It is an object to improve tubing in a well.
It is another object to reduce the cost of wells by enabling use of less expensive synthetic hose in relatively deep wells.
It is another object to improve the method in which hose is deployed in a well.
Accordingly, the present invention is directed to a deep well flexible hose and method of deploying the same. The hose includes well flexible hose for use in extracting fluids and gases from deep wells, comprising a relatively flexible hose portion being of a length sufficient to extend to an operable position within the well, wherein the hose portion is of a predetermined weight load capacity and elasticity factor such that when the hose portion is so disposed in the well to the operable position, the hose portion's elasticity factor is exceeded due to the weight load normally exerted and means fixably connect to the hose portion for preventing the hose portion's elasticity factor from being exceeded at the operable position due to the weight load.
A method is also provided. The method is directed to disposing flexible hose for use in extracting fluids and gases from a relatively deep well and includes the steps of:
providing a relatively flexible hose portion being of a length sufficient to extend to an operable position within the well, wherein said hose portion is of a predetermined weight load capacity and elasticity factor such that when said hose portion is so disposed in the well to said operable position said hose portion's elasticity factor is normally exceeded due to weight load existing thereon;
fixably connecting means to said hose portion for preventing said hose portion's elasticity factor from being exceeded at said operable position by said weight load; and
deploying said flexible hose portion with said preventing means into the well.
