3 25,883 v. CROWELL GAS ENERGY CONTROL HEAD FOR OIL WELLS Filed March 31, 1923 2 Sheets-Sheet 2 WITNESSES fl TTORNE YS my invention herewith shown and describedis to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of m invention, or the scope of the subjoinedcaims- 1 An importantfeature of the present invention relates in .the provision of the single valve 31 positively though adjustablg connected to the tubing and cooperable wit manner described.
Sometimes, oil and as is found cavernous strata, instead 0 porous sand bodies. In such cases,'the 011 and water has'free movement through the limestrata, and the oil is not definitely segregated .in the lime, above the water by gravitiv, as it is common to find them separate in a true sand. And in such instances, it is common for the water to choke the'oil away from the'welll bore, and the well flows water. It has been found in practice, that by choking the well tubing, a
charge tubing and having anchoring means; controlled by the discharge tubing, a con-- in, at surface, the invasion of the water is delayed, and the well flows oil. And it s common practice to choke thewell in on" tate therewith and top.
Now, with this device, means is rovided for positively and definitely preetermlning and regulating the de ree of opening p a wells a headfiior coupling with a packer,
through which the well may flow.
Also the regulation of .fiow, is down close .to the source of flow energy (which is the expansion of gas), so that the regulation is bound to be more positive, a desirable result.
I claim 1. In a device of the character described.
foruse with oil and gas wells, dischar e packer associated with the distrol head arranged upon the packer, and co-operative valve means carried by thecon -trol head and discharge tubing for posithe valve seat of the'co'ntrcl head in the,
nall
tively and definitely regulating the degree of opening through said valve means.
2. In a device of the character described for use with oil and gas wells, discharge tubing, a packer associated with the discharge tubing and havin anchoring means, a control head arranged upon the'packer, and co-operating valve means carried by the control headand discharge tubin roviding means for pre-determining an definitely regulating the degree of valve opening.
3. In a device of the character described, a control head including a tubular body portion adapted to be connected with the anchor packer arranged within the casing of an oilwell, tubing extending down mto the oil well and having a nipple connected to its lower end and extending into the tubular body portion of the control head, a spider connected with the control head and having a hub provided with internal screw threads, the periphery of the nipple being provided with screw threads engageable with the internal screw threads of the head of the spider whereby as the tubing is turned the nipple and tubing are longitudishifted with respect to the control the upper end of the control head behea provided with a valve seat, and'a single va ve of annular form and havin its openg ing provided with screw threa s and engageable with the screw threaded; nipple whereby the valve is adjustable on the nipple though normally constrained to ro-- artake of the motion thereof, the valve being cooperable with the valve' seatof the control head.
4. 111 a control device for oil and gas said head having a valve seat and an escape port at its upper end a tubular mernber having-screw threaded engagement in the head and adapted to be connected with a discharge tubin and a valve imm'ovably fastened on the-tubular member and adapted to enga e the seat of the head, said valve being adjusted to and maintained at, a definite distance from its seat, by a positive rotation of the tubular member, whereby the flow of fluid between the valve and its seat may be controlled to a definite and predetermined degree.
