Carboniferous fracture-developed area prediction and hydrocarbon evaluation in Northwestern Junggar Basin

摘要

The previous study result of Carboniferous volcanic rock weathering crust reservoir on northwestern in Junggar basin is fracture pore double-media. It has been a hard task for long time on exploration and development. Recently, with the technical development in seismic interpretation, it is possible to research carboniferous reservoir with seismic attribute. Using the comprehensive seismic attribute integrating geology, logging and other data, Carboniferous fracture-developed area has successfully been predicted in 4-2 area and 9 area and hydrocarbon evaluation is carried out. Finally perfect efficiency is obtained
