英文摘要 | N-2, Ar and He was found in the mud of Chinese Continental Scientific Drilling(CCSD) hole from 300 similar to 2045 m. The Nitrogen varies between 75.5% and 88.7%, Ar varies between 0.126% and 1.13%, and He between 0.0006 and 0.029%. The N-2/Ar ratio is ranged from 71.11 to 622.22. The geochemical characters of N-2, Ar and He indicate that the major composition of the mud is result from air containmination, but a part of extraneous fluids are added in the muds. The relationship between the concentrations of N2, Ar, He and ratio of N-2/Ar and the depth of CCSD well, suggests that there are six periods of fluid below 300m. They are 300 similar to 469m, 469.5 similar to 891 m, 891.5 similar to 1174 m, 1203.5 similar to 1492 m, 1520 similar to 1773 m, 1773.5 similar to 2045 m. We found that extraneous fluids were added into the piolet well mud during the periods of 469.5 similar to 891 m, 891.5 similar to 1174 m, 1203.5 similar to 1492 m and 1773.5 similar to 2045 m, but no extra fluids were added during the periods of 300 similar to 469m and 1520 similar to 1773 m. It's assumed that N-2, Ar and He generated from different sources( crust fluid natural gas, and magma fluid) migrate into the CCSD piolet well. |
