摘要：

以科罗拉多T. A. Cross成因地层研究组为代表的高分辨率层序地层学问世后,立即得到学术及实业界有识人士的高度重视,实际应用效果显着,这标志着层序地层学的新发展。高分辨率层序地层学着眼于沉积矿产,特别是油气勘探中具体目标的精确预测。以地层过程一响应沉积动力学为理论基础,具体有四,即:地层基准面原理、体积划分原理、相分异原理与旋回等时对比法则。油气勘探开发实践证明,该方法对相分布、储层三维预测、流体流动数值模拟物理模式的建立有着重要意义。

关键词: 高分辨率, 层序地层学, 基准面, 体积划分, 相分异, 等时对比

Abstract:

When high-resolution sequence stratigraphy represented by T. A. Cross Genetic Stratigraphy Group of Colorado School of Mines was introduced to the pubic,it immediately drew the attention of academic circles.The practical effect in application is remarkable.This marks a new development in sequence stratigraphy.The high-resolution sequence stratigraphy introduced in this paper focuses on more accurate prediction of sedimentary mineral deposit,especially concrete objective of oil and gas exploration.The high-resolution sequence stratigraphy takes the stratigraphic and sedimentary process-response dynamic principles,including the principles of stratigraphic base level,volumetric partition,factes differentiation and rule for chronostratigraphic cycle correlation as its theoretical bases.The practice of hydrocarbon exploration and development has proved that the high-resolution sequence stratigraphy has significant importance in factes analysis,3-D prediction of reservoir and the establishment of petrophysical model for fluid-flow numerical simulation.
