摘　　要：为了探索油气成藏构造地质预测系统(包含构造建造、构造改造和构造地貌),提出了油气成藏构造相系—构造网络—构造地貌三重预测设想,探讨了构造地貌控藏的观点和构造相系控藏的观念以及构造网络导运构造—封闭构造—容纳构造控藏的理念,指出构造地貌控藏所注意的是正地形景观,构造相系关注的是含油气建造垂向和横向的变化,构造网络注重的是各地不同深度的脆韧过渡转换带和各种断裂性能的鉴定以及断裂组合要素的配置,这随着构造层次的加深,三者的重要性依次增强。认为对油气成藏预测系统的关注和探讨,有助于油气地质科学的自主创新和勘探开发的持续发展。In this context, the triple forecast, which consists in the morphostructure, tectonic facies and tectonic networks on oil and gas-forming reservoir, is an exploratory research on scientific system of the geological forecast involving tectonic formation, tectonic reworking and morphostructure. Therein, the viewpoints about morphostructure-controlling reservoir, tectonic facies-controlling reservoir and tectonic network controlling reservoir which consists of transmission structure, sealing structure and accommodation structure are introduced. The positive landform is considered in the morphostructurecontrolling reservoir, the vertical and horizontal variations of hydrocarbon-bearing geological formation are done in the tectonic facies-controlling reservoir, and the brittle-ductile interbedded zone in different depths and combination of various mechanical property of deep faults is thought in the tectonic networkcontrolling reservoir. With the tectonic intensity, the function of three viewpoints is preferred used in turns. The attention and discussion to forecast system of oil and gas reservoir structure is helpful to the independent innovation of oil and gas geology and the continuous development of exploration and exploitation.
