英文摘要: Elemental sulfur (S o) and high-pressure hydrogen sulfide (H 2S), the first recorded occurrence of both from a well in northern Alaska, were encountered in the Husky 1 Inigok exploratory well in 1978. Located about 100 mi (160 km) southwest of Prudhoe Bay, the well was targeting an anticlinal structure on the northeast flank of a large late Paleozoic basin beneath the coastal plain and foothills region of the eastern National Petroleum Reserve in Alaska. The sulfur and gas first appeared at a depth of 17,570 ft (5355 m) while drilling in dark-gray to black organic carbon-depleted Carboniferous limestones (the Lisburne Group) at a temperature of 347°F, well above the melting point of S o. Solidification of the molten sulfur by cooling during the drilling operation caused the drill-stem to stick and delayed drilling operations for several months before being released. To determine the nature and source of the sulfur and H 2S and to establish any relationship between them, we performed chemical analyses on S , drilling mud, and cuttings. Numerous holes and vesicles in some sulfur samples indicate the presence of gas, but other samples, without vesicles, contain sharp edges, fractures, and x-ray diffraction patterns characteristic of ortho-rhombic and not amorphous sulfur, thus arguing against a molten source in these samples. Isotopic values suggest that the sulfide in widely separated mud samples has a common source, and that the δ 32 S values for S o are slightly more enriched in 32S in all deeper samples. The S o from the drill pipe at 17,240 ft (5254 m) has a δ 34S value similar to that of the sulfur in mud samples. The results appear to indicate that H 2S is the source for the S o. Copyright © 2012.
