Abstract
The main controlling factors are complex for the reservoir formation in the Mesozoic Jurassic of the Loess Plateau area in the western Ordos Basin.In the areas without three-dimensional seismic data,success rates in drilling only based on two-dimensional seismic data are low.To improve the success rate in drilling,this paper focuses on the Jurassic channel sand reservoir feature and adopts a time-frequency electromagnetic(TFEM)dual-side and dual-source excitation and multi-line receiving oil and gas detection technology scheme.Through experiments in the ZB area of the western Ordos Basin,a TFEM acquisition,processing,and interpre-tation technology scheme suitable for the the Loess Plateau area is developed:two targeted acquisition scheme designs and three targeted processing and interpretation techniques.The GeoEast system is used for intelligent oil and gas prediction of TFEM multi-parameters based on deep learning.According to the results of TFEM in-terpretation,well Z6 is deployed and drilled in the abnormal area of TFEM strength,and industrial oil flow is obtained,which verifies that the TFEM prediction results are consistent with the real drilling results and con-firms the reliability of TFEM oil and gas prediction for Jurassic thin reservoir in the Loess Plateau area.关键词
