Abstract:
1. A multiple integral pressure transducer system for installation in downhole coiled tubing systems connected to the surface wherein each integral pressure transducer comprises: a. a pressure block housing; b. at least one retaining pin passing through the walls of the coiled tubing and through each pressure block housing; c. a pressure sensor mounted to each pressure block housing and connected back to the surface; d. at least one pressure inlet port opening through the walls of the coiled tubing and into each pressure block housing to convey formation pressure internal to the coiled tubing; e. wherein each pressure inlet port opening is in fluid communication through the pressure block housing to each pressure sensor; and f. wherein each pressure block housing exterior comprises external grooves that allow additional fiber or electrical cable lines for other downhole sensors to traverse past each pressure block housing without clamping to each pressure block.
