Abstract:

Integrated exploration of subtle reservoirs is a multidisciplinary research work under the framework of sequence stratigraphy with the information integration system as the platform, which can be performed in three stages, including basic data compilation, regional comprehensive evaluation and target prediction. In the basic data compilation stage, an information platform should be built to realize integrated management of multiple source data and achievements. The regional comprehensive evaluation should be carried out in the following steps, including the building of a regional isochronal sequence stratigraphic framework, study of the characteristics of sedimentary system and subtle traps, study of the reservoiring pattern of subtle reservoirs, and prediction and evaluation of the spatial distribution of subtle reservoirs, so as to illustrate the types, features, forming conditions and spatial distribution of the subtle reservoirs. Target prediction should be performed in steps including selection of the working area, high accuracy correlation of sequential framework, recognition and characterization of subtle traps and evaluation of oil/gas-bearing properties of subtle traps, so as to recognize and evaluate subtle reservoirs and finally determine the targets for exploration drilling. The information integration system can be developed on the basis of the COM GIS system and should have the functions of integrated management of petroleum exploration information and multidisciplinary data, comprehensive presentation and application of research achievements, as well as tapping mass data. Application of the integrated exploration methodology in the research of subtle reservoirs in Dainan Fm of Jinhu sag, Subei basin, shows that it is practical and effective.
