Quantitative evaluation and application of fault sealing based on Petrel integrated platform
摘要
Abstract
The fault system of Bohai P Oilfield is complex,with multiple periods and scales of fault activity leading to increased reservoir heterogeneity,posing big challenges to fine water injection management and safe and efficient development of the oilfield.Based on the lateral sealing mechanism of faults,the research on quantitative evaluation of fault sealing property and the evaluation of lateral sealing ability of faults is car-ried out to facilitate the fine water injection management and development plan design of oilfields.Through the well-seismic integration technology,by comprehensively considering the distribution characteristics of reservoirs,fault elements,and fault types,three main lithological configuration models are established.Using the Petrel integrated platform to establish a lithology docking profile(Allan map)and a fault mud ra-tio(SGR)distribution map,reflecting the alignment of sandstone and mudstone layers along the strike di-rection of the two fault walls,as well as the fault sealing performance judged by the SGR method.Statistical analysis was conducted on the correlation between lateral sealing pressure difference of oil reservoirs and fault SGR values in the study area.AFPD-SGR correlation analysis was conducted to form a fault sealing capacity chart and determine the range of fault sealing capacity.When SGR<8%,the fault opens,SGR 8%-28%is weakly sealed,SGR 28%-60%is moderately sealed,and SGR>60%is strongly sealed.The research results indicate that the SGR method can evaluate fault sealing ability,and the fault sealing a-bility chart provides a good guidance for well network optimization and water injection development,which provides a good reference for the development of similar complex fault block oil fields.关键词
