Abstract: A sensing system that includes a cylindrical body including an internal flow channel that channels a first fluid therethrough, and a sampling chamber. The sampling chamber is in flow communication with an ambient environment. A venturi device is coupled within the cylindrical body, and the venturi device includes a high pressure portion and a low pressure portion. The low pressure portion is in flow communication with the sampling chamber. A valve is coupled within the cylindrical body and is positionable in at least a first position. A first flow channel is defined between the internal flow channel and the high pressure portion through the valve. The first flow channel channels the first fluid towards the high pressure portion such that the low pressure portion draws a second fluid into the sampling chamber from the ambient environment. A sensor assembly determines characteristics of the second fluid within the sampling chamber.

Abstract: A downhole power generation includes a power generation module for providing power to a load. A turbine is driven by flow of a downhole fluid to rotate. A generator is coupled with the turbine for converting rotational energy from the turbine to electrical energy, and an AC-DC rectifier is coupled with the generator for converting an alternating voltage from the generator to a direct voltage. A power conversion circuit couples the AC-DC rectifier with the load. The power conversion circuit is configured for providing a first power to the load when the load is in a working mode and providing a second power to the load when the load is in a non-working mode. The second power is less than the first power. A downhole power generation method is also disclosed.

Abstract: A downhole power generation system is disclosed, which includes a turbine generator system. The turbine generator system includes a turbine, a generator coupled with the turbine and having an AC-DC rectifier, and an optimized power control unit. The turbine is driven by flow of a downhole fluid to rotate. The generator converts rotational energy from the turbine to electrical energy and outputting a direct current voltage. The turbine generator system is coupled to a load via the optimized power control unit. The optimized power control unit controls to regulate an output voltage of the generator and provides a regulated output voltage to the load so that the turbine generator system has an optimized power output. An optimized power control method for a downhole power generation system is also disclosed.
