摘要:
This disclosure is directed to a connector apparatus for a semi-flexible tubing. The connector apparatus includes an inner sub having a first end disposable within a semi-flexible tubing and a second end connectable to various other downhole tools. The first end of the inner sub includes at least one depression disposed thereon that is generally alignable with at least one depression disposed on the semi-flexible tubing. The connector apparatus also includes an external sleeve disposable outside of the semi-flexible tubing. The external sleeve having at least one opening disposed therein generally aligned with the at least one depression in the first end of the inner sub. This disclosure is also directed to a method of installing the connector apparatus on a semi-flexible tubing and a method of running the semi-flexible tubing and a downhole tool into a wellbore via the connector apparatus disclosed herein.

This disclosure is related to a perforator tool and a method of using the perforator tool to perforate a formation. The perforator tool can include a first and second sleeve and optionally a third sleeve. The perforator tool can also include at least one perforation opening and at least one circulation port. The sleeves are slidably disposed within the perforator tool and can be displaced to permit perforation of the formation, block the perforation openings and open circulation ports.

A multi-channel downhole telemetry system for enabling communication in a wellbore. The system includes a downhole transmitter operable to optically transmit a first data stream on a first optical channel and a second data stream on a second optical channel. A downhole receiver is operable to receive the first data stream and the second data stream. An optically transmissive fluid disposed in the wellbore provides a medium for the optical transmission of the first data stream and the second data stream between the downhole transmitter and the downhole receiver. The optically transmissive fluid contains suspended solids having refraction surfaces that scatter the optically transmitted data streams in the wellbore.

Multiplex (+/−) stranded analyses, such as array comparative genomic hybridization (aCGH), are provided for detecting chromosomal rearrangements associated with cancer and other diseases. For example, an illustrative multiplex array for CGH includes discrete plus (+) strand and minus (−) strand DNA probes, complementary to each other but separable on the CGH array. The minus (−) strand DNA probes recover diagnostic information lost to conventional microarrays, since many genes transcribe from the minus (−) strand. In an illustrative system, patient and control DNA samples are prepared for CGH by amplification and labeling using comprehensive primers that generate both plus (+) strands and minus (−) strands of DNA in the samples. The breakpoints of a translocated chromosome may be detected on a multiplex microarray by DNA probes of one polarity, while DNA copy number changes associated with the translocation region may be detected by corresponding DNA probes of the complementary polarity. Related methods for identifying translocation partner genes are also provided.

Embodiments of methods and apparatus for high temperature operation of electronics according to the invention are disclosed. One embodiment of the invention generally includes an integrated circuit package having a substrate. A plurality of integrated circuits are coupled to a surface of the substrate. A lid is positioned above the substrate facing the surface. One or more pieces of compliant and thermally conductive material are compressed between at least one of the integrated circuits and the lid. The lid defines in part an enclosed volume containing the compliant and thermally conductive material.

A downhole fluid flow control device (188) and method for minimizing erosion are disclosed. The downhole fluid flow control device (188) includes a downhole surface (190) subjectable to an erosive stress (196, 198) which may be a moving fluid or an erosive agent, for example. A shape memory alloy (192) is integrated with the downhole surface (190) in order to provide erosion resistance by reversibly transforming from an austenitic phase (194) to a martensitic phase (200) in response to the application of the erosive stress (196, 198). Further, the shape memory alloy (192) reversibly transforms from the martensitic phase (200) to the austenitic phase (192) in response to the presence of sufficient heat.

A downhole oil and water separator for an oil well includes a water-selective membrane disposed in a production flowpath of the well. The water-selective membrane is operable to selectively pass water from the production flowpath to a disposal zone to increase the concentration of oil in the production flowpath at the surface.
