The Study Of Precipitation Facie And Reservoir Quality Of Chang 6 Reservoir In Zichang Oilfield

Chang 6 reservoir act as one of important reservoir in Zichang oilfield of Yanchang petroleum company,in pace with more and more exploratory development,it is necessary for the study of precipitation facie and reservoir quality of Chang 6 reservoir in Zichang oilfield,so I choose the study of precipitation facie and reservoir quality of Chang 6 reservoir in Zichang oilfield as my thesis topic. After the study of the style and quality of Chang 6 precipitation facie and chang 6 sand body,the regular pattern of oil how to accumulation of chang 6 reservoir is also need study,it is favour of oil exploration in future.First of all, we get to know the formation quality according to the geology background. Based on this factors we analyse the character of chang 6 reservoir.Secondly,we learn about the style of precipitation facie according to signals of chang 6 precipitation facie,After that we sum up the character of chang 6 precipitation facie.Then we analyse the formation quality of chang 6 reservoir from seven factors,such as the quality of formation,the structure of pore in formation and so on.After that we evaluate the chang 6 formation according to the study of reservoir quality.At last,we summary the regulai pattern of how to accumulate of chang 6 reservior according to we study already.What’s more,we analyse the formation which be easy to explore and it is benefit for oil exploration in future.
