according to paleo-geomorphology and depositional systems analysis, three kinds of forming models of subtle traps were built . they are fan-delta front-slope-sliding turbidity subtle traps n sub-fan near fault-stepping faults-turbidity subtle traps and fan-delta-furrow-sub-fan-sliding turbidity subtle traps 综合分析表明,临南洼陷具有有利的油气成藏条件,发育有上倾尖灭型隐蔽油气藏、透镜体隐蔽油气藏、断层-岩性隐蔽油气藏等隐蔽油气藏。
rule reasoning, fuzzy decision and information fusion algorithm are merged, and the step fault diagnosis method is accomplished; for different object, when necessary knowledge is given, a special fault diagnosis system will be automatically produced, and the diagnosis result will be given 将规则推理、模糊决策、多传感器信息融合算法融为一体,形成一阶梯式故障推理机制;对不同的诊断对象,只要设置好必要知识模块,就可自行生成一专用故障诊断系统,并能自动输出诊断结果。
