摘要： The strength of a proppant or sand control particulate may be improved by coating the proppant to form a composite. The composite has enhanced compressive strength between about 34 to about 130 MPa and minimizes the spalling of fines at closure stresses in excess of 5,000 psi. Conductivity of the proppant pack in the fractures is further enhanced due to the increase in strength of the particles.

摘要： An apparatus for generating power includes a fluid chamber configured to receive borehole fluid, one or more conductive coils surrounding the fluid chamber, a reciprocating magnetic shuttle disposed in the fluid chamber and dividing the fluid chamber into a first volume and a second volume, a first conduit connected to the first volume, and a second conduit connected to the second volume, the first conduit and the second conduit extending from a tubular conduit to an annulus. The apparatus includes a switching assembly configured to alternate between a first operating state where the first volume is in fluid communication with the annulus and a second operating state where the first volume is in fluid communication with the tubular conduit, to alternate a direction of differential pressure between the first volume and the second volume and cause the magnetic shuttle to move in a reciprocating motion and generate an electric current.

摘要： A downhole assembly includes a first tubular including a first shoulder and a second tubular including a second shoulder. The assembly further includes a transmission element having a first portion disposed in the first shoulder, the first portion includes an electrically conductive member having a first arc length and a second portion disposed in the second shoulder. The second portion includes a contacting element having a second arc length that is substantially less than the first arc length and further includes an outer insulating carrier that defines a groove. The contacting element is disposed in the groove. When the first tubular is joined to the second tubular, the contacting element contacts the electrically conductive member and the second portion defines at least one region between the electrically conductive member and the second portion in areas of the groove where the contacting element does not contact the electrically conductive member.

摘要： A motor includes one or more actuator, one or more one passive members, and one or more pushing members. The actuator(s) vibrate along a first axis. The vibrations vary a dimension of the actuator(s) as measured along the first axis. The passive member(s) rotate around a second axis that is substantially parallel to the first axis. The pushing member(s) are positioned between the actuator(s) and the passive member(s). The pushing member(s) are fixed to the actuator(s) and have a contact surface frictionally engaging and applying a mechanical force to the passive member (s). The pushing member(s) have an asymmetric rigidity along the first axis. The motor and a power consumer may be conveyed into a wellbore. The motor may be energized to supply mechanical power to the power consumer.
