The fault segmentation of blank area in the east of Pubei Oilfield is strong, and the distribution of oil and water is complex. In view of this kind of situation, we did sedimentary microfacies research in study area. First, we established isochronous stratigraphic framework of the east of Putaohua oil layer by core and logging data ,we also established six well logging facies models, including main underwater distributary channel,underwater distributary channel,edge of underwater distributary channel,main sand sheet,sand sheet and bay mud between distributary channels;Secondly, we described the sedimentary microfacies of development area, summarized the evolution of sand and sedimentary microfacies characteristics of Putaohua oil layer; Finally, on the basis of the above work, we drew the sedimentary microfacies of study area. The study provides geological basis for the next step of exploration and development in oil field.

Based on the detailed core data and logging data from Toutai oil field and applying correlative technique of fluvial facies reservoir, through guiding wells selection, key beds determination, progressive oil layer subdivision of all wells, fine stratigraphic classification and correlation are carried out. The Fuyu oil layer in Toutai oil field is divided into 3 sand groups, 18 sublayers and 37 sedimentary units, consequently, monosandbody-scale isochronal stratigraphic framework is established, which can provide geologic basic data for further study on sedimentary microfacies, sand body distribution, oil and water distribution and favorable target prediction.

Xu 30 block is located in the southwest of Yushulin oil field, Putaohua reservoir is the main reservoir. Based on the analysis of the core information and well logging facies elements, and combining with the sedimentary characteristics of the study area, this paper discusses the types of sedimentary microfacies of Xu 30 block in Yushulin oil field in order to guide the future oil and gas exploration and development. The results show that the target layer in the study area having obvious characteristics of underwater distributary channel is delta front facies, and it can be divided into underwater distributary channel, seat body, sheet sand, the inner front sheet sand and the external delta front sedimentary microfacies. Further analysis of sedimentary characteristics, this paper establishes logging microfacies models and draws out 9 time units sedimentary microfacies in plane distribution diagrams. This study can offer not only an important geologic evidence for Putaohua reservoir at Xu 30 block, but also a basement for the distribution law of oil, water and the remaining oil.

Based on the analysis of the relationships between the conditions of structures, sedimentations, source rocks, cap rocks, faults, oil and gas migration passages and traps and hydrocarbon accumulation, the controlling factors of hydrocarbon accumulation and distribution was studied in Talaha-changjiaweizi area. It is held that the source rocks control the hydrocarbon vertical distribution, the drainage capabilities control the hydrocarbon plane distribution, fracture belts control the hydrocarbon accumulation of Talaha syncline, underwater distributary channel is a favorable accumulation environment and reservoir physical properties control the oil and water distributions. Therefore, it is concluded that source rocks, fracture belts, sedimentary microfacies and reservoir physical properties are the main controlling factors of hydrocarbon accumulation and distribution in Talaha-changjiaweizi area.

Putaohua reservoir is the principal producing formation in Daqing oilfield Xingbei block. The spatial distribution of single sand body is particularly important for the residual oil tapping in the middle-late stage of oilfield development. The paper studied sedimentary microfacies of Putaohua reservoirs in the zone, established high-resolution sequence stratigraphic framework of the area and a typical single sand body logging phase mode on the basis of logging features, finely portrayed single sand body type and spatial distribution on this basis to lay the solid geological foundation for oilfield subsequent residual oil tapping and provide a scientific geology guide.

Based on the Putaohua groups in Yushulin oil field, and through the statiscics and analyses, weve found that the reservoir property of this area is in the range of specially low permeability level. So due to the low porosity and permeability, its necessary to do some reaearch on the parameters calculation method.This papers analysed the relationships between the physical property parameters such as porosity, permeability, shale content and the well logging responses such as AC, SP, GR, then we built the distribution rules histograms of each physical property parameter. And we got the distribution situations of the parameters of the oil groups. Through the multiple regression, we built the relationship formulas between the reservoir property parameters and the well logging responses by using the core analysis data of 53 test wells. Afetr comparing the parameters of calculation and the core analysis data, we found that the deviation is small, which meets the production requires of oil field.
