    摘要: A stop collar assembly used for axially securing and/or to resist axial sliding of a downhole tool device. The assembly provided on a housing of the downhole tool and includes a generally annular ring having an inner circumference beveled outward proximate to the ring edge. A clamp ring having a raised portion on its outer surface is disposed adjacent and substantially coaxial with the annular ring. Pushing the annular ring against the clamp ring compresses the clamp ring onto the housing to resist axial sliding of the annular ring.

    摘要: A connector for a downhole tool includes a body with one or more conductors positioned at least partially axially adjacent to an axial bore that extends at least partially through the body. In embodiments, one or more seals surrounding the body prevent fluid from flowing from a lateral opening into the interior of the downhole tool. Additionally, the body of the connector can include a circumferential or annular recess that acts as a reservoir to contain or capture fluid that might otherwise enter the sub. Leak protection can also be protected by applying a pressure compensating material around the body.

    摘要: A universal joint between adjacent, electrically connected instrument housings for downhole well operations allow the connected housings to bend longitudinally as required to traverse an arced section of a well bore but does not permit relative elongation or twisting about the longitudinal axis of the housings. In one embodiment, a fluid impermeable open passage space at atmospheric pressure surrounds electrical signal carriers linking the instrument circuitry within the two housings. The passage is constructed as a high-pressure flexible bellows or as a braided or spiral wound high-pressure fluid hose. In another embodiment, a fluid impermeable sheath surrounds the signal carriers and encapsulates the signal carriers by a resilient solid. The articulation structure comprises a Cardan-type of universal joint wherein two fingers project longitudinally from the end of each of the housings. The fingers are meshed and pivotally joined to respective spindles projecting radially from the open center of a ring spyder. The protective bellows, hose or resilient compound filled sheath is secured at opposite ends to bore plugs in the respective instrument housings. Between the instrument housings, the hose, bellows or filled sheath passes through the open center of the spyder ring.

    摘要: A logging tool system for analyzing the carbon dioxide concentration in a fluid sample downhole in a borehole. A chamber is filled with the fluid sample and is closed to isolate the fluid sample from the borehole. The interior chamber volume is expanded to decompress the fluid sample, and a transmitter discharges light in the mid-infrared range. A sensor measures the absorbance of mid-infrared light by the decompressed fluid sample and generates a signal representing the carbon dioxide concentration. Mid-infrared light absorbance in the range between 4.1 and 4.4 microns can be analyzed by the processor to identify the carbon dioxide concentration in the fluid sample, and infrared absorbance in the mid-infrared range between 3.2 and 3.6 microns can be analyzed to identify methyl and metheylene components. A wiper cleans the transmitter and sensor between readings to reduce measurement errors caused by fluid sample contamination.
