主权项

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 the pressure block housing; c. a pressure sensor mounted to the 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 the pressure block housing to convey formation pressure internal to the coiled tubing; e. wherein the pressure inlet port opening is in fluid communication through the pressure block housing to the pressure sensor; and f. wherein the pressure block housing exterior comprises external grooves that allow additional fiber or electrical connector lines for other downhole sensors to traverse past the pressure block housing without clamping to it.
