    摘要： The invention provides a method for quantitative downhole surveillance of a multi-phase flow, comprising at least two phases of either oil, water or gas, in a petroleum well. The method comprising providing at least one shunt chamber which comprises a flow phase separation section, a delay chamber, one or more outlet ports, at least one flow restrictor and a tracer release system with one or more tracers. The method comprises separating a shunt flow in the shunt chamber into a low-density flow phase and a high-density flow phase; releasing at least one tracer into the tracer delay chamber. The method also comprises passing the separated low-density flow phase and high-density flow phase through each flow restrictor and flushing out the low-density phase flow and the high-density phase flow with tracer from the shunt chamber through the outlet ports into the local flow inside the well. The method comprises monitoring the at least one tracer in the production flow at a detection point downstream of the outlet ports and measuring

    摘要： An adaptive fluid switch for regulating the production rate of a fluid. The adaptive fluid switch includes a fluid control valve having a self-impinging valve element with at least one dissolvable plug configured to initially block fluid flow therethrough. After dissolution of the dissolvable plug and when the fluid produced through the adaptive fluid switch has a viscosity greater than a first predetermined level, the fluid follows a low resistance flow path in the self-impinging valve element but when the fluid has a viscosity less than a second predetermined level, the fluid follows a high resistance flow path in the self-impinging valve element, thereby regulating the production rate of the fluid responsive to changes in the viscosity of the fluid.

    摘要： A downhole sampling tool includes a tool body defining an opening therein for drawing a formation fluid into the downhole sampling tool. At least one sampling vessel is carried in the tool body and is operatively coupled to the opening to receive the formation fluid therein. A closure member is selectively engageable with the opening to prohibit flow of the formation fluid through the opening, and a biasing mechanism is operably coupled to the closure member. The biasing mechanism biases the closure member into engagement with the opening and is responsive to an increase in hydraulic pressure on the exterior of the sampling tool to a predetermined threshold pressure to permit movement of the closure member away from the opening and permit flow of the formation fluid through the opening and into the sampling vessel.
