Practice and understanding of rolling exploration and development in Shennan structural belt

In view of the characteristics of Shennan structural belt,such as fractured structure,big variance of reservoir space and complex oil-water relationship,with the application of3D seismic data fine processing,fine interpretation,logging evaluation,directional well drilling technology technologies,and by fully utilizing geology,well logging,mud logging and analytical data,the comprehensive geological study has been carried out,which realized the low-degree exploration and development evaluation and rolling exploration and development of uncompartmentalized reservoir.Two reservoirs,Ze70in upthrow side and Ze10 in downthrow side have been found,with the reserve scale of 10-million-ton.These effective rolling exploration and development methods provide meaningful guidance for complex structure belts.
