Comprehensive and Quantitative Evaluation for Oil-gas-bearing of Fault Traps in Combination of Lower Generation and Upper Reservoir:An Example from Ed1 in the East of Number 2 Structure of Nanpu Depression
摘要
Abstract
Based on an analysis of factors affecting the oil-gas-bearing of the fault traps in Nanpu Depression,a comprehensive and quantitative evaluation of the oil-gas-bearing of 8 fault traps of Ed1 Formation in the east of number 2 structure of Nanpu Depression was conducted using fuzzy comprehensive evaluation,with an aim to provide a guide for oil and gas drilling there.The parameters used in the evaluation included types of oil source fault,ratio between sandstone and stratum thickness,types of the structural belt encompassing the fault trap, not faulted thickness of Ed2 ,and fault's lateral sealing capability of caprock.The results showed that all the three drilled fault traps where oil-gas was present had a value larger than 2.The drilled fault traps with higher values had higher oil-gas shows;on the other hand,lower values indicated lower oil-gas shows.As to the three undrilled fault traps,T4-51N fault trap exhibited the highest success rate of drilling,T4-21N fault trap implied a certain risk of drilling,and in T3-12S fault trap,wells should be drilled into the aquifer.关键词
