Distributions and geochemical significances of 18α(H)-neohopanes and of 17α(H)-diahopanes in oils from west Xialiaohe depression of the Bohai Bay Basin have been studied. Relative abundance of 18α(H)-neohopanes and of 17α(H)-diahopanes can be effectively used as maturity parameters, in a range of medium-high mature stage, based on consideration on sedimentary-organic facies of source rocks. With a dual geochemical significance of maturity and sedimentary-organic facies, neohopane and diahopane parameters can be well used in oil-source correlation and in petroleum population division. Formation, primary concentration and preservation of precursors of rearranged hopanes are closely related to depositional conditions such as Eh-pH and clays content. A series of probable diahopanes (series D) was detected in the oils, which exhibits a similar distribution pattern and geochemical behavior as that of 17α(H)-diahopanes (series B).

The buried-hill trend is a typical style of the petroliferous structure in the faulted basin of eastern china. The Xinglongtai structure trend in the liaohe subbasin,Bohai Bay Basin is a buried faulted-hill trend resulting from the periodic faulting of the Tai’an-Dawa faults. The structure was cut by various faults,which are interlinked and constitute the conduits for {2. migration. {2. accumulated in the Tertiary sandstones and pre-Tertiary basement of metamorphosed rocks through the migration pathways of the fault system. {2. in the structure was derived from different hydrocarbon kitchens to form a hybrid field complex. {2. charged the structure from different directions and accumulated in various reservoirs through different pathways in different times. The accumulations in the buried hill trend of Xingongtai are composed of two types of traps in the two stratigraphic systems: traps in the Tertiary sandstones were formed by the fault blocks and by the pinchout of the sandstone,and traps in the pre-Tertiary basement of metamorphosed rocks were formed by fissures in the inner part of the buried hills and by the unconformity near the surface of the buried hills.

The liaohe Oilfield in the liaohe Western Depression of the Bohai Gulf Basin is the third-largest oil producing province and the largest heavy oil producing oilfield in{2.. A total of 65 oil samples,35 rock samples and 36 reservoir sandstone samples were collected and analyzed utilizing conventional geochemical and biogeochemical approaches to unravel the mechanisms of the formation of the heavy oils. Investigation of the oils with the lowest maturity compared with the oils in the Gaosheng and Niuxintuo oilfields indicates no apparent relation between the maturity and physical properties of the heavy oils. It is suggested that the heavy oil with primary origin is not likely the main mechanism re-sponsible for the majority of the heavy oils in the liaohe Western Slope. The absence and/or depletion of n-alkanes etc.,with relatively low molecular weight and the occurrence of 2.-norhopane series in the heavy oils as well as the relatively high acidity of the oils all suggest that the majority of the heavy oils once experienced secondary alteration. The fingerprints of the total scanning fluorescence (TSF) of the inner adsorbed hydrocarbons on the reservoir grains and the included hydrocarbons in fluid inclusions are similar to that of the normal oils in the area but are different from the outer adsorbed and reser-voired free oils at present,further indicating that most of the heavy oils are secondary in origin. Analyses of bacteria (microbes) in 7 oil samples indicate that anaerobic and hyperthermophilic Ar-chaeoglobus sp. are the dominant microbes relevant to oil biodegradation,which coincides with the shallow commercial gas reservoirs containing anaerobic bacteria derived gas in the Gaosheng and Leijia teotonic belts. The biodegradation most likely occurs at the water/oil interface,where the forma-tion water is essential for microbe removal and nutrient transportation. We think that biodegradation,water washing and oxidization are interrelated and are the main mech

Tancbeng-Lujiang fault system is one of the largest strike-slip fault systems in eastern *** extends southward to Beibuwan Bay to the west of Hainan Island and northward through Lujiang of Anhui Province, Tancheng of Shandong Province and Luobei of Heilongjiang Province in china to the territory of Russia. Its formation is related to the subduction of Kula-Pacific plate to the Asian continent. It is oriented approximately parallel to the eastern edge of Asia. It is dominated by the sinistral translation from Jurassic to Eocene and then by dextrose strike-slip. It has the following characters: (1)clear linear character; (2.sharp dip angle, usually changing between normal and reverse faults; (3)showing braided structure on the plan and flower structure in section;(4)alternated by uplifts and sags along the fault belt; (5)many stages of the eruptions of alkaline to calc-alkaline basalt magma along the fault belt; and (6) frequent activities of earthquakes along the fault belt. Its control over the oil-gas distribution is shown by the following racts: (1) the formation of many oil-bearing fault depressions; (2. the increase of the basin area it has passed through, thus increasing the basin's subsiding quantity and the oil reservoirs; and (3)the formation of many kinds of oil-gas trap structures.
