There are two classification including volcanic lava and volcanic clastic rock, totally 15 types in Yingcheng Formation, Yaoshen area. The lithology is mainly characterized as acid rhyolite, tuffs and volcanic breccia. By using logging data and seismic data, the authors come to the conclusion as follows: there existed five types of lithofacies of volcanic lava in this area, with eruption-overflow facies most widely developed. The section is characterized as eruption mixed with overflow, superposed eruption-overflow facies and volcanic sedimentary facies occurred far from the crater. There are frequent volcanic activities, multi-periodic activities of volcanic eruption developed, thus multi-periodic eruption modes were formed. This area is overlapped and connected in the plane, adjacent eruption facies are often connected, overflow facies are distributed on lave platform.

The main purpose of lithofacies modeling is to get the actual reservoir lithofacies skeleton model which is maximum approximation of the underground reservoir. The facies model can effectively solve the problem of predicting sand bodies between wells. At the same time, we still use the stochastic modeling method to build the facies model of unconstrained single well simulation and sedimentary facies controlled constrained simulation. We elected the model which is most consistent to the actual geological conditions, providing theoretical guidance for characterizing the interwell sand body distribution law and improving the accuracy of predicting sand bodies between wells, laiding the foundation for further exploration and development of oil reservoir.

Compared with 2-point variogram-based geostatistics, multiple-points geostatistics is able to delineate reservoirs of complex spatial architecture or geometries more accurately. Multiple-point geostatistics stochastic simulation is introduced to apply on delta reservoir modeling by taking 2Sa block in a certain oil field at BeiBuWan basin for example. At first, the training image of 2Sa block deposited in delta frontier of study area is established by digitizing sedimentary facies and then facies model of 2Sa block is created with the method of multiple-point geostatistics. The result indicates that facies model simulate the sedimentary microfacies space distribution as well as distribution law of sandbodies, which provides a guiding significance for predicting the distribution of effective sand-body in the study area.

This paper describes an ongoing multidisciplinary study on the development of the barrier islands in the Danish Wadden Sea (Vadehavet), carried out by the Department of Geography and Geology at the University of Copenhagen and the Geolo gical Survey of Denmark and Greenland (GEUS). Nine sediment cores each c. 25 m long and a total of c. 45 km ground penetrating radar (GPR) profiles have been acquired on the islands of Rømø and Fanø. Geochemical and palaeontological analyses and dating of 150 core samples using optically stimulated luminescence (OSL) are in progress. This multidisciplinary approach has given new insights into the sedimentary architecture and development of the island, and the study is expected to result in a new detailed facies model. Such models are essential for an assessment of the effects of rising sea level associated with global warming. The new facies model can also be used as an analogue for subsurface oil or water reservoirs in similar sedimentary settings. This article presents selected core and GPR data from the Rømø barrier island.
