摘要： A downhole gamma ray density measurement system is described. The gamma ray density measurement system includes a pressure housing and a gamma ray source within the pressure housing. One or more detectors within the pressure housing detect gamma radiation. One or more low-attenuation inserts may be located in the pressure housing near the gamma ray source and/or one or more of the detectors. One or more high-attenuation inserts may be located in the pressure housing near the gamma ray source and/or one or more of the detectors.

摘要： An actuation assembly (100, 300) for actuating a downhole tool (200) having a tool housing (202) and an actuation member (208). The actuation assembly (100, 300) includes a downhole power unit (100) and a stroke extender (300). A power unit housing (150) is operably associated with an extender housing (302). A moveable shaft (130) of the power unit (100) is operably associated with an extender mandrel (304). The extender housing (302) is operably associated with the tool housing (202) and the actuation member (208). The extender mandrel (304) is operably associated with the actuation member (208) such that oscillatory movement of the moveable shaft (130) relative to the power unit housing (150) causes oscillatory movement of the extender mandrel (304) relative to the extender housing (302) which causes progressive movement in one direction of the actuation member (208) relative to the tool housing (202), thereby actuating the downhole tool (200).

摘要： A method for operating a well tractor is presented. The method involves running a well tractor coupled to a wireline into a wellbore and supplying an amount of electric power to the well tractor to operate the well tractor at a first speed to urge the wireline through the wellbore at a first force. A variable gear ratio transmission of the well tractor is adjusted and an amount of electric power is supplied to the well tractor to operate the well tractor at a second speed different than the first speed to urge the wireline through the wellbore at a second force different than the first force based on adjusting the variable gear ratio transmission.

摘要： The wireline release includes a shaft having one end releasably connected to the end of the wireline by a connector and being held in the latched position by a fusible material ring. Upon activating heaters in the cable head from the surface via conductors in the wireline, the fusible material ring is melted allowing the shaft, under the tension of the wireline, to shift to an unlatched position whereby the connector releases the wireline from the shaft and cable head. The connector includes a plurality of collet members which, in the latched position, are biased into the connection with the end of the wireline and are then released upon being shifted to the unlatched position where the collet members move to a disengaged position.

The compression assembly (500) includes a support assembly (502) and an anti extrusion assembly (504). The support assembly (502) has a running configuration in which link arm assemblies are substantially longitudinally oriented and an operating configuration in which short arms (514) are pivoted relative to long arms (520) of link arm assemblies such that the short arms (514) form a support platform. The anti extrusion assembly (504) is operably associated with the support assembly (502). The anti extrusion assembly (504) has a running configuration in which petals (536) are substantially perpendicular to a base member (534) and nested relative to one another and an operating configuration in which the petals (536) are radially outwardly disposed substantially filling gaps between the short arms (514).
