摘要： Methods and related apparatuses and mixtures are described for spectroscopic detection of hydrogen sulfide in a fluid, for example a formation fluid downhole. A reagent mixture is combined with the fluid. The reagent mixture includes metal ions for reacting with hydrogen sulfide forming a metal sulfide, and a capping agent that limits growth of the insoluble metal sulfide species by electrosteric or steric stabilization. The particle growth is one of chemical reaction or significant aggregation, and the capping agent further functionalizes the reagent mixture to exhibit properties outside the natural characteristics of the metal sulfide species to allow for spectroscopic detection of the metal sulfide species. The combined mixture and fluid is then spectroscopically interrogated to detect the presence of the metal sulfide thereby indicating the presence of hydrogen sulfide in the fluid. The mixture also includes chelating ligands for sustaining thermal endurance of the mixture under downhole conditions.

摘要： Methods and devices for mixing a first fluid with a second fluid downhole include a chamber having a first end, a second end and an opening for fluid to flow there through. A top surface of a perforated piston is capable of contacting the second end and a top surface of a piston is capable of contacting a bottom surface of the perforated piston. The perforated piston is located at a first position within the chamber based upon characteristics of a first fluid. A first fluid delivery system supplies the first fluid and a second fluid delivery system supplies a second fluid to the chamber, wherein the second fluid is at a pressure that moves the piston approximate to the first end. An actuating device applies a force against the bottom surface of the piston to inject the fluids through channels of the perforated piston to produce spray droplets.
