Car Exhaust In Junggar Basin Son District Shawan Group Of Oil And Gas Sand Fine Seismic Interpretation And Favorable Area Prediction

The Sha Wan information currently has been considered as the major exploration strata in the district of Cha Paizi in the Junngar Basin. Untill now, the events of drilling and exploration have no breakthrough on this area in the past. Between2007and2008, the PetroChina did a rolling development on Sha Wan information in the area of89th well district. At the meantime, the area of95th well district has also under rolling development and5test wells has been drilled. Most of wells in this area have been obtained the commercial oil flows.With the base of strata division of Sha Wan information underground and accurate identification of layer on seismic profile, a confirmed interpretation scheme has been set. With the further identification on the detail condition of each layer of Sha Wan information, this article describe a clear image on the facture system and space condition of No.2Sha Wan strata including the features of these factures. This article also contains the the current features of structure of each layer located in Sha Wan information and Ta Xihe information in this area. A preliminary analysis on the history of major structure of Sha Wan information in the Che Paizi district has also been studied. With the data of analysis of logging response, forward modeling, attribute analysis and inverse modeling, a predication for the further potential exploration area has been made, especially a locate analysis on the lithological reservoirs combing with the current type of reservoirs in Che Paizi district. According to analysis, we make the first layer of Shawan group as the target layer, in addition, we do the appropriate research to the lithology and structure of the second la yer of Shawan group. This article describes eleven structural and lithological reservoirs with53.08km2in the total area through the identification and description on the underground structure and lithology of Sha Wan information in the Che Paizi district. There are4traps in the first layer of Sanwan group, the tatal area of which is25km2, and there are7traps in the second layer of Sanwan group, the total area of which is28.08km2, the study shows that this area has great exploration potential.All the research works indicate there is a massive potential exploration capability on this area in the further.
