Study On Sedimentary Facies Types And Distribution Regularity Of Block Kam 607

At present,the main problems exist such as serious water intrusion,uneven use of oil reservoir,imperfect knowledge of block structure,poor well condition and poor conventional effect.The main starting point of our study is: the geological situation of the oilfield,the data obtained as the starting point,combining with the previous research results,we have studied the sedimentary facies types and stratigraphic sequence characteristics of the block on the one hand,and,on the other hand,we have studied the sedimentary characteristics,small layer division,reservoir characteristics and so on by digesting various kinds of data.Through the analysis of the comprehensive geological data in the laboratory and the site,the main block 607 in the study area is the building oil layer and the Xinglongtai oil layer,and a total of four oil formation groups,which are in the building oil group,the two oil group in the building,the Xinglongtai one oil group and the Xinglongtai two oil group.After comparison and analysis,we divide the four oil formation groups in the first oil formation,the two oil formation in the building,the Xinglongtai one oil group and the Xinglongtai two oil formation to be divided into 7 lower grade sandstone groups,of which there are 23 small layers.Through further analysis of the logging data and other related data,we have obtained that the sedimentary subfacies of the Jin 607 block are mainly fan delta front deposit,and the source direction comes from the northwest of the study area.Through further analysis of the study area,we have divided the microfacies,mainly from the subaqueous distributary channel,the estuarine dam,the matting sand and the underwater distributary Bay four microfacies.We found that the main deposits in Jin 607 block are mainly underwater distributary channel,which has good reservoir property and high permeability,which is beneficial to the development of reservoir,which provides a direction for further exploration of reserves and adjustment and development.
