INVENTOR. Jo; ep ./l/ Foes-as United States Patent 3,504,695 NATURAL HEAT MANIFOLD Joseph N. Rogers, P.O. Box 353, Marrero, La.
Filed Aug. 3, 1967, Ser. No. 658,222 Int. Cl. E21c 43/12; F161 53/00 US. Cl. 137340 1 Claim ABSTRACT OF THE DISCLOSURE The present invention relates to a natural heat manifold arrangement in which gas lift of oil wells in maintained at the beginning of the winter and continues throughout to the end of the winter without the wells ceasing to cause the flow of gas so that the wells do not die because of a gas lift choke freezing.
An object therefore of the present invention is to provide oil well apparatus that is adapted to continued use during freezing winter temperatures without the loss in production due to the gas well dying because of a gas lift choke becoming frozen under winter conditions.
The above and other objects and advantages of the invention will become apparent from the following detailed description and accompanying drawings in which:
FIG. 1 is a side elevation view of the head end of an oil well using the natural heat manifold of the present invention;
FIG. 2 is a front elevation view of the natural heat manifold in accordance with the preferred embodiment of the present invention; and
FIG. 3 is a side elevation view of FIG. 2 in crosssection, taken along lines 3-3 thereof, and in which there is shown in exploded view the cage nipple bean and the insert choke therefor.
Referring now to the drawings, there is shown an oil well head having a production valve 12, a hot oil line 14 from the production valve 12, a natural heat manifold 16 comprising a short hollow section of pipe 18 forming a manifold housing, the housing having a hot oil well inlet nipple 20 and a hot oil outlet nipple 22.
There is shown passing through the housing 18 in a transverse direction to the flow through the housing of the oil, a gas lift line 30 which passes through the housing in a straight path terminating on the opposite side in a gas lift line 32 that is coupled to a casing valve 36 at the oil well head.
"Ice
FIGS. 2 and 3 show the features of the natural heat manifold in more detail, and when it becomes time to valve down the gas lift line because of decrease in gas flow therein, then the gas lift line 30 is adapted to have inserted therein a cage nipple 40 which is of hollow passage construction and in which there is provided a threaded portion 42 to engage a threaded portion 44 terminating in a flange 46 within the cage nipple 30.
Similarly, when it is desired to reduce further the gas flow therein, an insert choke 50 is provided to be inserted similarly within the cage nipple bean 40, the insert choke 50 having a small passageway therethrough so that it engages by a threaded portion 52 with the threaded portion 54.
Additional embodiments of the invention in this specification will occur to others and therefore it is intended that the scope of the invention be limited only by the appended claims and not by the embodiment described hereinabove. Accordingly, reference should be made to the following claim in determining the full scope of the invention.
What is claimed is:
1. A natural heat manifold comprising a short hollow section of pipe consisting of a manifold housing having a nipple inlet for hot oil at one end and a nipple outlet for hot oil at the other end, a transversely disposed cylindrical nipple cage extending centrally through the housing having threaded ends and an opening therethrough of a given diameter, a fittingly engaged cage nipple bean to threadedly engage the inner surface of said nipple cage and having its opening therethrough of a smaller diameter than the dimension of said given diameter, and an insert choke for interfittingly threadedly engaging the inner surface of said cage nipple bean, said nipple bean and said insert choke removable when a union connection is opened, said insert choke having its opening therethrough of a smaller diameter than the dimension of said diameter of said nipple bean.
