Specification of Letters Patent.
Application filed August 16, 1911.
Patented Nov. 28, 1911.
Serial No. 644,278.
To all whom it may concern:
Be itknown that I, GEORGE H. TRAINER, a citizen of the United States, residing at Salem, in the county of Harrison and State of West Virginia, have invented a new and useful Gas-W'ell Construction, of which the following is a specification. 1
This invention relates to an improvement in tubing for gas wells.
The primary object of this invention is to provide means for utilizing the casing head as as well as the high pressure gas.
A Further object of the invention is to facilitate the flow of gas and provide means for prolonging the flow of the casing head gas.
It has been found that in removing the casing head gas from the ground the gas supply will cease as soon as water accumulates in the well tubing above said supply, the casing head gas not having suflicient force to expel the water or oil thus accumulated. When the water or oil rises and stops the flow of gas the well is termed drowned out, it heretofore having been found impossible to economically and conveniently remove the water or oil in order that the flow of the casing head gas may be continued.
In the drawings :Figure 1 is a view showing a gas well equipped with the improved mechanisms. Fig. 2 is a detail view of the pipe section and valve members shown in Fig. 1, and Fig. 3 is a View showing a modified form of valve.
In Fig. 1 it will be noted that the well casing is continued to the point A which is immediately above the inlet of the casing head gas which will be at approximately a ressure of 500 pounds. This flow of gas Wlll continue until the water or oil rlses within the casing effectually choking off the supply. Arranged within the casing 10 is a tube 11 which extends within the well a considerable distance deeper than the inlet for the casing head gas, the end portion of said tube being perforated and extending to a point where the high pressure gas which will be at approximately 1000 pounds will enter the tube and be conducted by the same to suitable distributing pipes. In the removal of this high pressure gas the pressure of the same is great enough to overcome the water pressure and thereby prevent choking of the well. As the low and high pressure gas is found in the same well the object of the present invention is to utilize a portion of the high pressure gas to expel the oil or water which may accumulate to choke the casing head outlet. In carrying out this idea the tube 11 is formed with an enlargement 12 at a point below the low pressure inlet and in order to prevent the igh pressure gas from escaping down the tube 11 and passing through the casing 10 the well is closed by the packer 14 which embraces the tube 11 and which is arranged at a point above the high pressure flow. Thus .the high pressure gas will be compelled to flow Within the tube 11. When water or oil has accumulated above the low pressure inlet, a suitable gate is opened in the upper portion of the tube 11 and the pressure in said tube lowered. When the pressure in said tube is equal to or less than the pressure in the casing the water accumulated above the casing head gas inlet enters the enlargement 12 of the tube 11 through the valve 15, the water or oil which has entered said tube 11 through the valve 15 being forced out of the tube 11 thus efiectually draining the well adjacent the casing head flow.
The water and oil may be ejected through the tube 11 by pressure less than that which is back of the same in the outer casing, as the friction is too great in the outer casing for even 500 pound pressure to elevate the same. In this manner the casing head flow may be at all times kept unobstructed and the supply of gas which has heretofore been wasted may be utilized. While the valve 15 may be of any suitable construction the construction shown in Fig. 2 has been found in practice to be effectual, its construction consisting of the intake pi e 16 which is normally closed by the flap 1 and which when in its 0 en position is disposed at an angle to the slde wall of the coupling 19 in order to direct the water upwardly. This valve is supported by section 21 of the casing in order that the same may be readily removed for the purpose of repair.
In Fig. 3 of the drawings, a slightly modified form of valve is shown. In the form shown in Fig. 2 the inward movement of the flap 17 is restricted by the stop 17', but in the modified form, the flap is provided with a bifurcated extension 22, a curved arm 23 carried by the extension 16 resting between the bifurcations of said extension. This curved arm being formed with a stop 23, which contacts with the bifurcation to restrict the movement of the flap.
It will be noticed from the foregoing that casing head gas which is for certain pur poses as valuable as the high pressure gas may be exhausted from the earth in the same manner as the high pressure gas and the choking or drowning out of the casing head gas will be effectually prevented. It will be noted that the casing head gas may be removed from the casing and supplied to any suitable pipe line and the high pressure gas removed independent of the first mentioned gas or the same may be co-mingled after they have been raised from the well. Attention is called to the fact that structure other than that shown in the drawings may be employed in carrying out this method of relieving the drowned out casing head flow.
What is claimed is 1. A device for raising liquid from gas wells, consisting of a high pressure outlet tube, a low pressure outlet casing, and a valve arranged in said high pressure tube, below the intake of the low pressure casing.
2. A device for raising liquid from gas Wells, consisting of a high pressure outlet tube, a low pressure outlet casing, a valve arranged within the high pressure tube below the intake of said casing, said valve consisting of a pivotally supported member, said member when in its open position assuming an angle to direct the fluid upwardly.
3. A device for raising liquid from gas Wells, consisting of a high pressure outlet tube, a low pressure outlet casing, a valve arranged in said high pressure tube, below said casing, said valve consisting of a pivotally supported member and a stop carried by said member and contacting with said casing to hold said pivotally supported member at an angle to said casing when open.
In testimony that I claim the fore oing as my own, I have hereto aflixed my signature in the presence of two witnesses.
