She majored in Sedimentology in Chengdu University of Technology and was granted master degree in June of 2010Abstract Wangguantun oilfield is in Wangguantun, county of Cangxian, Hebei ProvinceIts regional tectonic zone located in the west of Kongdong fault of Kongdian tectonic belt, which is in the south part of Huanghua depression. This thesis targeted the Guan 15-2 block at Wangguantun and took the third member of Shahejie Formation as research object. Some theories and technologies such as Sedimentology, high resolution sequence stratigraphy, mineral petrology, Geophysics, Petroleum Geology were applied as well as a plenty data of drill core, well drilling, bore log and seismDepend on the former research and a core of “high resolution sequence stratigraphy --- depositional system--- lithofacies paleographic”, the sedimentary facie characters of the third member of Shahejie formation in Guan 15-2 block were systematic researched and some results and new cognitions came out as below: 1 Theories and methods of high resolution sequence stratigraphy which took Cross base-level cycles as guiding ideology were integrated with the data of seism, drill core, well drilling and bore log. The third member of Shahejie formation in Guan 15-2 block was analyzed by a detailed high resolution sequence stratigraphy and classified by one super-long-period cycle sequence, three long-period cycles LSC1 LSC2 LSC3. Based on the existed stratigraphy subdivision methods of the third member of Shahejie formation in Guan 15-2 block, the high resolution sequence stratigraphic features and structures of target area were systematically studied and a high resolution sequence strata framework was found with long-period cycle units2 Combining the sedimentary facie marks and previous research results, a systematic sedimentary facie division was done at the third member of Shahejia formation in Guan 15-2 block. Three sedimentary facies of lake delta, sublacustrine fan and lacustrine were classified. Every sedimentary facies could be divided into different sub-facies and micro-facies. A sedimentary pattern which accorded with theIIAbstract local geological conditions of study area was modeled3 Depends on the main mapping units with long-period cycle, three sequence-lithofacies paleographic maps with different period LSC1-LSC3 were compiled respectively. Overall, there was a process of lake water deepened gradually during the sedimentary period from LSC1 to LSC3, and the delta front back to the direction of NE. The lake water achieved super-long-period imum flooding during LSC3 deposit period. Sedimentation period LSC1, it mainly developed lake delta and lacustrine sediment delta front sand shows a North-east-South-west show long banded cloth delta front sand bodies are surrounded by shallow lake mud, sedimentation period LSC2, delta front sand bodies retreated to the NE direction obviously shallow lake sand bar scattered in front of the delta front sand bodies, lake water is relatively deeper than that of the sedimentation period LSC1, it developed mouth bar and distal bar microfacies types in local area. Sedimentation period LSC3, delta front lobate sand bodies retreated to the NE direction continued it developed sublacustrine fan and bathile subfacies in front of the delta front sand bodies at the same time, lake water became further darken than that of sedimentation period LSC2, lake water reached the imum flooding of the super-long-period cycle Key words: Guan 15-2 block; the third member of Shahejie formation; high resolution sequence stratigraphy; sedimentary facies; sequence-lithofacies paleographic map compilationIII 1 High-resolutionSequence Stratigraphy 2007 1995 “ - ” 1995 1996 1997 2000 2001 2004 2007 20082000 2001 2003 2008 2000 2002 2005 2006 1996 1999 20071 20 10 20070001977 , 1988 1996- 15-2 II 2 1 15-2 15-215-215-2115-22 15-23 15-24315-2 -15-21-1 1-1 4 1 5250km 50-100km 17000 km2 12000 km2 2-1 40-60km 120km - 6 2 7 1 4000 1 2 800m500m 1800m 3 82 2 2/315-2 1 9 I I 2 300 80013002050?80 30 65 2-21 2 3 45 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 10 2 300 lOOm 4 5?1 2 5?1 22506 104 27 24 23104 27 185 197 998 100 4 2-1 1 2500m 2 3000m T6; T3 3000m 2-1800 1000m 11 100-300m 2-3 3 100~2000m 12 213 “ ” Cross1994 Cross T A1994 Vail P R1987 Johnson J Getl1982 Galloway W E1989 Cross -143-1 50Ma 5 10Ma0.5 5Ma0.08 0.5 Ma 0.08 0.5 Ma 15-24 15 1 3-1 2 3-2 163 3-3 -“” “ ” 3-4 -- 17 3-5 2005 -2005 2007 20072008 1815-21SLSC13 LSC1 LSC2 LSC3 3-2 3 15-219 20 3-5III3-1 VailIII1.0-4.0Ma, 400- LSC1-LSC3 - Vail 2.5.3 5Ma 30 50m 60m ? 3-5 3-6 C 3 5 C 1 A 2 4 C3-7 - - II Vail 1991 1 SLSC 3-8 SLSC121SLSC1 22 2324 Van Wagoner,199015-2 Cross T A1994 25 15-2- 3-13 142 2 26 27 28 60Walther Fisher 1970Brown 1973 McGowen 1974 Galloway 1975Frazier 1975 1976 Weimer 1976 Busch 1977 Crowell 1977 Lowensarm 1978 Newell 1979Wanless 1980Davis 1992 1996 2002- 15-215-2 2915-2 4-1 4-1a b4-1a 16-7 - ES3 4-1b 19-4 -15-24-1 15-24-1A 4-1B 0.5 1.0cm 15-2 17-54-1C 15 20cm1.0cm 15-23031 15-24-1E 15-8 2250.24-1F 15-0 2136.3m 15-62125.4m 4-1G 15-24-2 15-2 32 1980 1994 2005 4-34-31999 33 15-21 - 4-4A B4-4 A4-4 B 9-8-515-024-5 3 4-6 4-5 4-6 19-6 17-3 34
