Well pumping system and installation method

In a pump system for installation in a well penetrating an earth formation, apparatus comprising:

• a pulldown anchor operable to be lowered into a wellbore for said pump system, said pulldown anchor including a body member, means for receiving a flexible cable connected to said body member for lowering said pulldown anchor into said wellbore and means for engagement with a wall of said wellbore to substantially prevent movement of said pulldown anchor upwardly in said well;
• a casing anchor adapted to be lowered into said well, said casing anchor including an anchor body and means mounted on said anchor body for movement to a position to engage said wellbore wall to forcibly retain said casing anchor in said well;
• an elongated casing having a lower end thereof connected to said casing anchor;
• and
• means for connecting a flexible cable to said casing anchor for pulling said casing anchor into said well with said cable trained through said means for receiving said cable on said pulldown anchor whereby said
• casing is operable to be positioned in said well upon pulling said casing anchor and said casing into said well with said cable.

A well pump system for installation in a wellbore penetrating an earth formation, said pump system comprising:

• an elongated tubing string extending from a wellhead into said wellbore;
• a pressure fluid actuated pump anchor connected to said tubing string;
• a release valve operably connected to said pump anchor;
• and
• a fluid lifting pump operably connected to said tubing string in such a way that said release valve is interposed between said pump anchor and said pump;
• said pump anchor including a member operable to be biased into forcible engagement with a wall of said wellbore in response to pressure fluid acting thereon for retaining said tubing string and said pump in a predetermined position in said wellbore.

A method for installing a pump system in a well comprising an elongated wellbore extending within an earth formation, said method comprising the steps of:

• lowering a pulldown anchor into said wellbore and securing said pulldown anchor at a predetermined position in said wellbore;
• moving a casing anchor into said wellbore by pulling said casing anchor into said wellbore with flexible means engaged with said pulldown anchor, said casing anchor being connected to one end of an elongated casing;
• and
• causing said casing anchor to be anchored in said well at a predetermined position while connected to said casing for retaining said casing in said well.
