摘要： A collet assembly for a pressure controlled well testing apparatus includes a cylindrical collet housing defining an open interior. A collet mandrel is disposed in the open interior. The collet mandrel is movable within the collet housing between a first position and a second position. A collet is disposed radially outwards from the collet mandrel and radially interior to the collet housing. The collet further includes a finger extending radially outwards from the collet. The finger engages a detent of the collet housing when the collet mandrel is in the first position and the finger deflects to move past the detent when the collet mandrel moves to the second position. A method of testing a well includes providing a pressure controlled tester within a wellbore. A first bias pressure is provided to a mandrel of the pressure controlled tester. A second bias pressure is provided to the mandrel. A pressure is applied to the wellbore. The location of the mandrel translates when the wellbore pressure is greater than the second bias pressure. The translation of the location of the mandrel moves the ball valve from the closed position to the open position.

摘要： A tool that is usable with a well includes a valve element, a mechanical operator, a pressure chamber and a regulator. The valve element has a first state and a second state. The mechanical operator responds to a predetermined signature in an annulus pressure relative to a baseline level of the annulus pressure to transition the valve element from the first state to the second state. The pressure chamber exerts a chamber pressure to bias the mechanical operator to transition from the second state to the first state. The baseline level is capable of varying over time, and the regulator regulates the chamber pressure based on the baseline level.
