The conclusion sums up the evolvement characteristic of the two national mythology : the mythical culture of Mongolia is influenced by Buddhism mythology deeply, and the ancient mythology of the Manchu is influenced by other national mythical culture less that is still keeping original natural style. The taleization and epic characteristic of Mongol mythology is obvious. The Manchu mythology, as each clan of clan oracle, mythology, refreshing song, is mainly kept by the form of teaching orally generation by generation. Swan fairy maiden tale obtains different development in two nationalities. In the mythology of two national Shamanism, the worship form of hawk and vulture and the production of Shaman is derives from the common faith—Shamanism.
结论归纳总结了两个民族神话发展演变的特征,即蒙古族神话文化深受佛教神话影响,满族古神话受其他民族神话文化影响相对较少仍保留着原始自然的风格;蒙古族神话故事化、史诗化特征明显,满族神话作为各氏族部落神谕神话神歌主要通过世代萨满口耳相传的形式保留下来;天鹅仙女神话故事在两个民族中得到不同层次的发展;两个民族萨满神话中鹰鹫崇拜的形态和萨满产生母题来源于共同信仰的萨满教。

The geology research of carbonate reservoirs in Ordovician of Tahe oilfield showed that many large dissolved vugs and fractures were developed. The spread of the reservoir take on a very heterogeneous state. And the typical fractured-vuggy reservoirs was formed. According to the combination of the various spaces, the formation was divided into vuggy formation, fractured-vuggy formation and fractured formation. The research showed that development of the vug is relevant to the its position on the structure, the fractures, the water surface and the weathering surface. Multi-phase charge and recharge of the oil in the reservoirs resulted in the complexity of the fluid distribution. So the"Bottle Model"was brought forward to explain the movement of the water-oil contact. The special storage space and the complex fluid distribution lead to the unstability of the production and the complexity of the water cut. In order to explain the characteristic of the fracture-vug unit was brought forward and the basic principle and method of the partition of the fracture-vug unit was formed. The classification and evaluation of the units were performed according the reserve and energy. Based on the research of geology characteristic and the fluid flow in the reservoir the comprehensive numerical simulation plan of the fractured-vuggy reservoirs were established. Through the selection of the simulation unit, fluid flow type and parameter equivalent the triple media reservoir simulation model was established. Considering the practical application the model was resolved by the DKR decomposition conjugate grads method. Based on the fine reservoir description of Dsitrict IV of the Tahe oilfield the various space type were classified and combined together. The geology model of Unit S48 was constructed. Two typical single well model was established according to the geology and the dynamic phenomena. Finally the single well model and the Unit S48 were simulated by the triple media reservoir simulator. Via the local grid refinement and coarsening in the simulation good matchs were gained. Based on the results of the simulation the reserve distribution, percent of reserve produced in various space and the natural energy were analyzed. The fluid was storaged in the fractures and vugs mostly and more than 90% the produced oil came from the systems. The energy belonged to the active one. The results of simulation accorded with the fact and showed the validity and practicability the research and the simulator.
