Reservoir Description In YT2 Channel Sand Of 3th Member Of Triassic Tahe Oilfield

Triassic is the main stratum for Tahe O ilfield clastic rocks.Since the Triassic in the discovery of oil and gas,there have been many petroleum geologists of the sequence stratigraphy,sedimentary facies,geochemical and reservoir prediction has been done a lot of research work,and achieved a lot of understanding and new achievements.In recent years,a lot of research work were done constantly in the Triassic,sedimentary facies,reservoir and development characteristiccs,and has made a lot of new understanding,and put forward many constructive rolling exploration deployment recommendations,made a major breakthrough in the production practice.However,with the continuous adjustment and find new oil a nd gas exploration deployment and development plan of the Late Triassic period,and constantly update the development of information and rich,the Triassic fluvial sand body in the production and development of the contradiction is more and more prominent,for example,channel sand reservoir energy supply shortage,water development in the process of rapid rise,sand body connectivity problems,yield decreased obviously,the natural decline rate and other issues,has seriously hampered the Triassic channel sand efficient development goal,therefore,there is an urgent need for a more comprehensive,more systematic in-depth study of Triassic channel sand reservoir,and provide the scientific basis for the increase of storage yield,a solid foundation for future exploration well deployment of channel sandstone reservoir and reservoir development measures lay.At present,the channel sand well deployment and development problems,the causes,clear sand accumulation controlling factors,looking for high quality reservoir as the main line,sequence stratigraphy,petroleum geology,sedimentary petrology,sedimentology(including seismic sedimentology and reservoir inversion)under the guidance of the theory,the comprehensive utilization of geology,logging,seismic and chemical analysis data,sequence framework,the object layers of sedimentary microfacies,reservoir and oil and gas as the main controlling factors of reservoir are studied and analyzed,fine description of sand body,the oil formation in the well block five period channel 8 small layer division scheme system,carry out the work of fine reservoir description,combining the research results of hydrocarbon reservoir,based on the main controlling factors of oil and gas in the clear,prefer ably favorable target,The next step of the channel sand reservoir provide support for the Triassic Tahe Oilfield.
