Abstract: Système d'inspection sismique à chaînes multiples et utilisant une pluralité de rangées de géophones dans chaque chaîne. Chaque rangée de géophones peut être adressée individuellement par une unité centrale de commande. L'adressage des rangées individuelles de géophones est exécuté à l'aide d'un systeme de référence. Ce système de référence facilite également le contrôle de l'emplacement du point de tir par rapport au système multi-chaînes, ainsi que l'accès à des rangées individuelles de géophones en réponse au point de tir sismique.

Abstract: 57 A spring for use in geophones to suspend coils within a magnetic field assembly. The spring is formed from a disc and comprises an outer ring, an inner ring and three legs connecting the outer and inner rings, which legs are formed by removing portions of the disc in a predetermined pattern. The inner edge of each leg (7) lies on an arc having a radius at least 1.25 times greater than the distance from the center (9) of the spring (4) to the inner edge of the leg (7) at the point (11) where the leg joins the inner ring (6). Preferably each leg (7) is wider at its ends (10, 11) than it is in its middle (12).

The injector valve (10) comprises a valve cylinder (20) and a piston (18) which is displaceable in the valve cylinder (20). The valve cylinder (20) has an inlet channel (28) and an outlet channel (30) for connection into a flow line (12) for fluid flow through the valve cylinder (20) between the inlet and outlet channels (28 and 30). The valve cylinder (20) has a loading port (14) for loading a charge of a substance into the injector valve (10). The piston (18) has an injection passageway (22) which is positioned for the piston (18) to be displaceable in the valve cylinder between a loading position where the injection passageway (22) is in register with the loading port (14), and an injection position where the injection passageway (22) is in register with the inlet and outlet channels (28 and 30). An intermediate seal (78) is provided to provide a seal between the piston (18) and the valve cylinder (20), the intermediate seal (78) being positioned to be between the loading port (14) and the injection passageway (22) when the piston (18) is in its injection position; and a pressure balancing cavity area (82) is provided between the valve cylinder (20) and the piston (18) and is positioned to communicate with the intermediate seal (78) when the piston (18) is displaced between its injection and loading positions.

Abstract: A centrifugal drilling mud degasser (50) for use in degassing gas-cut drilling mud. The degasser comprises a casing (52) having an inlet port (54) for receiving a gas-cut drilling mud (72) and an outlet port (56) for discharging degassed drilling mud; a rotatable shaft (58) disposed longitudinally within the casing (52); a plurality of accelerating paddles (66) disposed along the longitudinal axis of the rotatable shaft (58) and attached thereto for moving drilling mud in a rotary motion to create a centrifugal force field and thereby create a vortex within such drilling mud such that drilling mud will move axially towards the outlet port (56), such that the heavier liquid/solid phase of the mud will be directed toward the inside wall (76) of the casing (52), and such that gas dispersed within the mud will escape from the mud inwardly towards the shaft (58) to discharge from the casing (52); and means (60) operably associated with the rotatable shaft for driving the rotatable shaft (58).

Abstract: A clamping apparatus for locking tools in a well is disclosed. A first piston sealably engages a hollow body member to form a chamber, which is filled with a working fluid. A bias member or spring moves the first piston, extending a clamping arm connected to the first piston against the well wall. A second piston is sealably engaged in a bore in the first piston; the bore is in fluid communication with the chamber. The second piston is driven into the bore by a motor, increasing the pressure in the chamber through a passage in the first piston between the bore and the chamber. This increased pressure further urges the first piston and locks the clamping arm against the well wall. The hydraulic pressure is released, and the clamping arm is unlocked, by opening a valve in a line between the chamber and a reservoir. The clamping arm is retracted by driving the second piston into the bore into contact with the first piston, forcing the first piston back against the spring.

Abstract: An improved seismic array and method of seismic exploration are provided which have the capability to supply data to separate recording stations simultaneously. The seismic array has a plurality of seismic detector connection points, and a seismic detector is located at each seismic detector connection point. The outputs of the seismic detectors are electrically isolated from each other, and weighting may be applied to the output of each seismic detector in the array. Two signal-carrying media are also provided in the array, and the weighted outputs of the seismic detectors are conveyed to the first end of the array over one signal-carrying medium and to the second end of the array over the second signal-carrying medium. A Chebychev weighted array is achieved by a proper selection of weighting.

Abstract: The invention is for a method of seismic exploration involving the generation of a nonlinear signal of predetermined shape at the output of a sweep generator which comprises the steps of dividing the sweep time of the output signal into a plurality of preselected time intervals, calculating the rate of change of the frequency of the output signal for each time interval to realize the predetermined shape based on the range of the sweep, the sweep time, the starting frequency and the predetermined shape, and using each value in the calculating step to change the rate of change of frequency of the sweep signal, and the invention includes the apparatus specifically adapted to carry out the inventive method.
