Computer Technology for Geophysical Exploration on Continental Facies Subtle Reservoir

摘要

With the high development of reservoir exploration techniques,the hydrocarbon exploration in the east of China has developed to that of subtle reservoir,which has taken series of difficulties and challenge. The geophysical technique as the key exploration method of subtle reservoir focuses on identifying and describing reservoir,especially on sand body. For the continental facies fault basin with various complex subtle reservoirs,a series of techniques suitable for channel sand body,glutenite,turbidite,beach bar,stratigraphy,complex buried hill and so on have been developed and applied in the subtle reservoir identification and description and have made great progress in actual exploration. This paper presents various geophysical methods,including the 3D visual interpretation and reserovir prediction techniques,which got quite good application results in actual production of Shengli Oilfield.
