    摘要： A flush valve for a multiple line hydraulic system includes a bifurcated manifold, the bifurcation being provided by a piston actuatable hydraulically, mechanically, electrically magnetically or by fiber optic means. The piston or gate is provided with a port extending diametrically therethrough and oriented to become coaxial with an inlet and outlet of the manifold upon actuation of the piston. With the port aligned the hydraulic fluid in the system can be displaced by fresh fluid. The piston is then deactivated which results in the port becoming misaligned with the inlet and outlet of the manifold. In this condition the hydraulic system is again sealed and functions normally.

    摘要： A system and method to log a wellbore, comprising a logging tool adapted to be deployed in a wellbore environment, the logging tool including at least one sensor for taking a measurement of the wellbore environment. The sensor is a fiber optic sensor and the system includes a fiber optic line in optical communication with the sensor. The data measured by the sensor is transmitted through the fiber optic line on a real time basis to the surface, Where the data is processed into a real time display. In one embodiment, the fiber optic sensor is a passive sensor not requiring electrical or battery power. In another embodiment, a continuous tube with one end at the earth's surface and the other end in the wellbore is attached to the logging tool and includes the fiber optic line disposed therein.
