Plastic well with plastic well adapter

A well adapter assembly (134) for supporting a well pipe (43) inside a casing (12) having a longitudinally-disposed casing axis (14), and for making fluid communication between said well pipe and a hole (16) that is disposed transversely through said casing, which well adapter comprises:

• a plug body (54) having a cylindrically-shaped surface (98) that is disposed coaxially with said casing axis, having a top (96), having a bottom (102) with an inlet port (104) therein, and having an outlet port (100) that communicates with said inlet port and that opens through said cylindrically-shaped surface;
• sealing means (56), being disposed circumferentially around said outlet port, for providing a fluid seal between said plug body and said casing that circumscribes said outlet port and said hole in said casing;
• locking means, comprising a recess (62) in said plug body (54), comprising a locking cam (58) that is disposed in said recess, and comprising an arcuately-shaped surface (72 or 74), for guiding said locking cam in an arcuately-shaped path around a pivot axis (76), for engaging said casing distal from said outlet port, and for forcing said plug body toward said hole in said casing, whereby said sealing means is forced into sealing engagement with said casing;
• retaining means, comprising a retaining pin (60) that is disposed coaxially with said pivot axis, for retaining said locking cam in said recess, and for permitting said locking cam to slide around said arcuately-shaped path while generally rotating around said pivot axis;
• adjusting means (66) for forcing said locking cam to slide around said arcuately-shaped path;
• support plate means (26, 138, or 158) for engaging said casing;
• support tube means (32), being disposed circumferentially around said casing axis, and being operatively attached to both said support plate means and said plug body, for supporting said plug body;
• and
• saddle means (18), being disposed outside said casing and being operatively secured thereto, for communicating with said hole in said casing and with said outlet port in said plug body.

An adapter plug assembly (38) for making fluid communication between a well pipe (43) that is disposed inside a well casing (12) having a longitudinal axis (14), and a hole (16) that is disposed orthogonally through said well casing, which adapter plug assembly comprises:

• plug body means (54), having a cylindrically-shaped surface (98), having a bottom (102) that is generally orthogonal to said cylindrically-shaped surface and that includes an inlet port (104), and having an outlet port (100) that communicates with said inlet port and that opens through said cylindrically-shaped surface, for insertion into said well casing with said cylindrically-shaped surface generally coaxial with said longitudinal axis, and for generally aligning said outlet port with said hole in said well casing;
• sealing ring means (56), being disposed circumferentially around said outlet port, for providing a fluid seal between said outlet port and said hole in said well casing;
• locking means, comprising a locking cam (58) that includes a first arcuately-shaped surface (72), and comprising a second arcuately-shaped surface (74) of said plug body means that slidably receives said first arcuately-shaped surface, for guiding said locking cam in pivotal movement around a pivot axis (76) that is orthogonal to said longitudinal axis and that intercepts both said locking cam and said plug body means, for engaging said casing distal from said outlet port, and for forcing said plug body means toward said hole in said casing, whereby said sealing means is forced into sealing engagement with said casing;
• retaining means, comprising a retaining pin (60), for retaining said locking cam in said recess, and for permitting said locking cam to pivot around said pivot axis;
• and
• adjusting means, being disposed substantially parallel to said longitudinal axis (14), for forcing said cam to slide around said arcuately-shaped path while generally rotating around said pivot axis.
