[Abstract]:The Archean buried hill in Sheng601--Shen 630 well area of Damingtun depression is the main exploration reservoir and productivity replacement block in Shenyang Oil production Plant of Liaohe Oilfield because of the strong heterogeneity of metamorphic rock buried hill. The lack of effective means for fine description of fractures is the main factor restricting the high efficiency exploration and development of the buried hill zone. It is urgent to solve three problems to be solved in order to realize the fine delineation of fractures in this area: the first problem is that the recognition and distribution of reservoir lithology is not clear, which leads to the difficulty of determining the areas where the dominant lithologic fractures develop; Problem two: some well logging interpretation conclusions are not consistent with production test and production test, and logging fracture identification standards are not uniform; Problem three: there is no supporting technical system for fracture prediction of acicular metamorphic rock buried hill, well and earthquake. In view of this, this paper aims at the problems faced by the exploration and development of Sheng601-Shen 630 buried hill belt. Based on the single well logging fracture evaluation and lithology identification, the distribution characteristics of single well fractures are determined. On this basis, the combination of well shock and dynamic and static is adopted. The idea of "from known to unknown" develops the fine description of fracture spatial distribution characteristics. Three studies are focused on: first, reservoir lithology identification and evaluation, and establishing the lithology identification standard of regional test well data. Identify the lithology in the area and determine the area where the dominant lithologic fractures develop; Second, the research of logging fracture identification and evaluation, making full use of conventional logging and imaging logging data to identify fractures, establish the standard of qualitative and quantitative identification of conventional and imaging logging of buried hill reservoir. It lays a foundation for the prediction of the next step fracture. Third, the joint application of a variety of technologies to implement the target area reservoir fracture distribution characteristics, focusing on the non-linear neural network, ant body analysis and other techniques of joint application, multi-means. The distribution law of fracture in Sheng601-Shen630 well area is forecasted from many angles to solve the defect and limitation of single method. Through the development of this study, the logging evaluation technology and fracture geological modeling technology for fractured reservoir are formed. The series of exploration and development techniques combined with post-stack seismic processing technology and fine fracture description technology depict the spatial distribution characteristics of fractures in the study area, and propose a new standard for the classification of fractured reservoirs and zoning evaluation. The fracture concentrated development area is determined. The type 鈪，
