| 摘 要： | 构造圈闭有效性的数学判别，是将以往的定性分析发展为定量分析。本方法以同沉积原理为基础，用数学方法分析的构造顶部与翼部的地层厚度变化关系，计算出了不同地质历史时期的构造生长指数，绘制地质年代与构造生长指数的关系曲线，进而结合分轩模拟结果分析构造圈闭的有效性。给出了本方法在海相碳酸岩地区某构造圈闭的应用实例。用此方法进行构造圈评价可使油气探更逼近目标，减少预探风险，提高钻井成功率。

| Abstract: | Using math analysis to identify the effectiveness of structural traps is a try at the identification from qualitative analysis to quantitative analysis. Based on synsedimentary principle, the method first ana- lyzes the variations of the structural thickness from top to flanks, calculates the growth index of the structure in different geologic time, then sets up a functional relation between geologic time and growth index, and further analyzes the effectiveness of the struc- tural trap with the help of the basin simulation. The paper demon- strates a case history of the structural trap analysis in marine car- bonate rock region. It is considered that using math analysis to e- as to reduce the exploration risks and improve economic benefit. |
