塔里木盆地非背斜圈闭的勘探方法

EXPLORATION METHODS FOR NON ANTICLINE STRAPS IN TARIM BASIN

根据塔里木盆地可能存在的非背斜圈闭的类型和地质特点，提出了勘探非背斜圈闭油气藏应采取的步骤和方法，以及依据异常高点验证圈闭的新思路。对其勘探的四个步骤和野外地震数据采集、常规精细处理、ＡＶＯ技术、反演技术、目标化解释技术、非背斜圈闭的表征及非背斜圈闭的评价方法等作了具体论述。寻找非背斜圈闭油气藏在于地震运动学与动力学信息的充分应用，在于地震资料的特殊处理和各种新技术的广泛采用。

Based on the analysis of possible types of non anticline straps existed in Tarim basin and its geological and geophysical specialities, the authors suggested some exploration procedures and geophysical methods needed for the expoloration of non anticline strapped reservoirs in Tarim basin and proposed a new idea of verifying straps by high abnormality. We described with details the four major exploration steps, and methods for data acquisition and processing, AVO technologies, seismic inversion techniques, target oriented seismic explanation methods, representation and evaluation technologies for non anticline straps of geophysical exploration methods. The discovery of non anticline straps will mainly depend on the application of seismic kinematic and dynamic information, target oriented seismic processing and widely use of new techniques.
