Abstract
1341666 Wells CAMCO INC 25 May 1972 [19 Nov 1971] 24641/72 Heading E1F A safety valve 10 is connected at each end to well tubing, and comprises a bore 14 of a size substantially the same as that of the tubing, a fluid line 32 for supply of control fluid to open the valve, means 40 for supporting a second safety valve 50 within the bore, a port 42 initially closed but openable for admitting the control fluid into the bore for controlling the valve 50 when supported in the bore. The valve 10 has a seat 16 surrounding the bore and engaged by a flapper 18. A sliding tube 22 is urged upwardly by the pressure of fluid and a spring 26 in a chamber 24, and is forced downwardly by the pressure of the control fluid entering a chamber 34 and acting on a piston 36 on the tube. In its downward position the tube holds the flapper open and in the upper position of the tube the flapper is closed by a spring 24a (the valve 50 not being within the bore). A shear sleeve 46 is operated to open the port. The valve 50 is supported by a well lock 52 engaging the recess 40 so that the port 42 is connected to a control port 64 in the valve 50 which has a flapper 70 opened by a sliding tube 74. The valve 50 has an extension 68 which holds the flapper 18 open.
