Abstract:Based on geophysical integration thoughts,seismic data fracture prediction techniques were integratedly applied in complex reservoir prediction and characteristics in this paper.In reverse fault development areas,the prediction and detection were conducted for every block and every layer,and then layer by layer over-all evaluation was carried out,as a result the difficulty for mapping reserve fault seismic attribute was solved.Through studies on fracture prediction,horizontal and vertical fracture distribution laws in Carboniferous different layers for Qidong area of Junggar Basin Northwest margin were understood.By analyzing oil test and production test results,the favorite development areas were optimized,excellent igneous rock reservoir prediction effects were achieved.
