库车山地高陡复杂构造圈闭研究思路与方法
|
摘要
库车山地高陡复杂构造圈闭研究受地震资料品质差和构造建模困难等不利因素影响,圈闭研究精度难以满足需要。为了提高圈闭研究的精度,在找出高陡复杂构造研究难点的基础上,有针对性地提出:继续进行采集攻关和处理解释一体化,尽可能多地占有地震、钻井和露头资料;加强速度分析并且使多种速度研究方法相结合和相互验证;运用断层相关褶皱理论进行精细浅深层构造建模。
Limited by various kinds of unfavourable factors such as the low quality of the seismic date,and quick variation of the velocity,the precision of highly steep complex mountainous region structure research in kuqa depression can not satisfy the demand of oil and gas exploration.On the basis of finding out the difficult point,continue tackling key problem of seismic acquisition and carry on the integrating of seismic date processing and interpretation.on the same time,chang method,utilizing seismic date,well date and outcrop date as many as possible.Methods which are the combing of different velocity analysis methods are used to enhance the velocity analysis,so that they can validate each other.Using fault-related folding theory,carry on fine structure modeling,in order to improve the precision of structure research.
