摘要： A universal joint between adjacent, electrically connected instrument housings for downhole well operations allow the connected hosugings 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. I 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 encapsutlates 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 while drilling and wire line system for analyzing the concentration of carbon dioxide or another substance, in a sample down hole in a bore hole. A chamber is filled with a sample that may be fluid, or condensate and gas. The interior chamber volume is selectably expandable for decompression of the sample. The sample may alternately be decompressed by allowing a sample at formation pressure to enter the chamber at a lower pressure, thereby decompressing the sample. A sensor measures the absorbance, transmittance or attenuated total reflectance of the infrared light. Mid and near infrared light is utilized to identify carbon dioxide, water and a plurality of hydrocarbons. A wiper cleans the transmitter and sensor between readings to reduce measurement error caused by fluid sample contamination.

摘要： A universal joint (21) between adjacent, electrically connected instrument housings (17, 18) for downhole 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 (31) at atmospheric pressure surrounds electrical signal carriers linking the instrument circuitry within the two housings. The passage (31) is constructed as a high-pressure fluid hose (40). In another embodiment, a fluid impermeable sheath (90) surrounds the signal carriers and encapsulates the signal carriers by a resilient solid (92). The articulation structure comprises a Cardan-type of universal joint wherein two fingers (72) 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 (29). The protective bellows (80), hose (40) or resilient compound filled sheath (90) 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.
