摘要： Methods and apparatus are described for forming a window of optimum dimensions in casing wall. A window of maximum width is cut when the center line of the mill tool is located inside of the inner diameter of the casing where a maximum amount of casing is drilled away by the mill tool. A whipstock is described which deviates the mill tool outwardly so that the center line of the mill tool is in approximately this position. The whipstock then maintains the mill tool at this approximate location until a window of desired length is cut having a substantially maximum width.

摘要： A mechanical set anchor wherein a plunger extending from a base end of an anchor body activates a pin type trigger which releases a spring utilized to set multiple slips extending from the body of the anchor. Continued downward compressive forces fully sets the slips into the borehole pipe casing. The slips are maintained in their fully set position by a locking nut. The anchor is mechanically released by an upward pull under tension of sufficient strength to shear release pins that release the compressed spring fully retracting the slips within the anchor body so that the anchor may be tripped from the borehole without interference from the previously engaged slips.

摘要： A retrievable whipstock which can be hydraulically set within a wellbore and following the drilling procedure mechanically released and retrieved for future use. The whipstock includes a whip which directs a milling tool from the main well and a hydraulically actuated packer or anchor for setting the whipstock in the wellbore. The retrieval tool includes a nose piece to ensure proper orientation relative to the whipstock and a die collar to threadably engage the whip. An adapter on the retrieval tool wedges the whip away from the casing wall to ensure mating engagement between the retrieval tool and the whip. The whipstock is released through the application of tension through the retrieval tool allowing removal from the wellbore.

摘要： A one-trip whipstock assembly incorporating a hydraulically set anchor which includes an interlock for maintaining the anchor in its set position upon interruption of hydraulic pressure. The anchor is connected to the lower end of the assembly which also includes a whipstock for diverting cutting tools and a locator sub for positioning the assembly in the cased well bore. The whipstock assembly is designed to be run into the well using a running string or a mill attached to the upper end of the whipstock in order to locate and set the whipstock and mill the casing in only one trip.

摘要： A valve body for use in cementing, fracturing or acidizing operations in well drilling with improved wear resistance to extend the operating life of the valve. The valve includes a hardened metal valve head having urethane legs replaceably attached to the valve head. A urethane valve insert may also be provided to facilitate sealing engagement with the valve seat. The urethane legs reduce the overall weight of the valve to reduce the mass of the pumping valve against the valve seat thereby extending the life of the valve. The valve legs are attached to the valve head through fitting engagement and can be replaced and/or repaired.

摘要： A whipstock mill for milling through the casing wall which incorporates a pressure drop tattletale to signal the operator that the milling operation should be halted. The milling tool includes a longitudinal fluid passageway which communicates with a lateral port formed below the mill blades. A replaceable plug is utilized to initially close the port thereby restricting fluid flow into the well hole. The starter mill is preferably run into the hole with a whipstock which can be set in the hole using an integral packer. As the mill travels down the set whipstock, a shear block mounted to the whipstock will shear the plug at a predetermined depth of the mill opening the lateral port. The resulting pressure drop within the milling tool signifies that the mill has reached the desired depth. Accordingly, the milling operation can be halted and the mill retrieved to permit further operations through the casing wall.

摘要： A packing assembly for a whipstock in which the whipstock can be run into a well casing to a level above the bottom and milling through the casing wall without having to make a round trip with the well string. The packing assembly includes slip-type anchors which initially set the assembly and packing elements which sealingly engage the well casing to seal off the casing while anchoring the device. Disposed between the packing elements is a spacer ring which is axially movable in response to the fluid pressure within the well casing to enhance the sealing engagement of the packing elements. The spacer ring includes an O-ring seal which provides improved sealing between the spacer ring and the inner mandrel to which it is mounted. In order to compress the packing elements while preventing extrusion thereof, an overleaf ring and retainer arrangement is provided thereby enhancing sealing engagement of the packing assembly.

摘要： A thermostat monitoring and controlling the temperature of produce ripening within an enclosure and featuring a bridge circuit sensing errors between the actual and desired temperatures in which the desired temperature is selected directly in units of degrees. A bridge amplifier having feedback maintains the bridge in electrical balance to avoid errors due to changes in bridge component self heating. An error detection circuit having a single control simultaneously selects upper and lower error limits centered on the desired temperature, in units of degrees. The circuit indicates whenever the actual temperature goes outside these limits. An alarm circuit indicates a temperature error or a power failure in the thermostat at the thermostat and at a remote location. This circuit utilizes an alternating current source which activates current direction-dependent indicators operating on alternate half cycles. Electrical isolation of the temperature monitoring circuitry from the circuitry controlling heating, cooling and fan equipments is provided by coupling a signal indicating a temperature error through a single electrically isolating interface to eqiupment selection and control circuitry at line potential.
