| Xie Gou Cha oildom is a new block which was developed in Wayaobao oilfield in recent years.At present,it is still in the initial stages of exploration and development, reservoir distribution is unclear, area deposition, structure, storage reservoir characteristics and reservoir characteristics of no clear. With the development of exploration and development, it is necessary to make a detailed description of the reservoir in the study area. In this paper, a large number of geological, core, drilling, logging and geophysical logging data, combined with study area practice methods and techniques,are used to study and evaluate structure, sedimentary, reservoir characteristics and reservoir characteristics of the study area. It is found that the reservoir development in this area is poor, and the development of the reservoir is mainly Chang2, Chang4+5, Chang6 oil reservoir, being chiefly the gentle west-dip monocline, with multiple nose-shaped uplift growth partly, the reservoir has the characteristics of low porosity, low permeability, and low oil saturation. The effective source layer mainly is Chang7’s Zhang Jia Tan shale and dark mudstone. The migration of oil and gas is mainly based on vertical and near distance. The reservoir distribution is closely related to the structure, Chang6 and Chang4+5 reservoir is mainly distributed in the area with steep slope and steep slope, and the distribution of the Chang2 reservoirs in the high position of the structure. Finally, to predict the favorable oil blocks,and to provide The geological basis for the later development of the whole block. |
