非地震技术在油气勘探开发中的作用
|
摘要
非地震技术是指地震勘探以外的其它物探方法 ,一般只应用于新区及外围盆地的早期勘探 ,普查基底起伏、地层展布、盆山关系。近年来 ,随着技术的进步 ,低成本、高效率的非地震技术在新区、外围的普查导向作用得到进一步加强 ,而且开始转向目标勘探 ,主要是面对地震无反射或低信噪比的地区 ,起到镶嵌补充作用 ;在油气被发现之后 ,非地震技术可以从宏观规律出发对油气范围边界进行预测 ,对构造的含油气情况进行评价 ;在油田开发中应用非地震技术进行时移监测 ,研究蒸气前驱动态 ,可以指导油气开发 ,提高开采效率。图 4表 1参 2
Non seismic techniques are usually used only to investigate the basal structure, stratigraphic distribution and basin mountain relationship in unexplored region and surrounding basin of earlier reconnaissance. Owing to the technical advances in recent years, non seismic techniques play a great role in target oriented exploration as well as their earlier reconnaissance. Non seismic techniques are mainly aimed at where is no seismic reflection or low signal noise ratio, and feature the mosaic based remedy effects. Non seismic techniques can be used to predict the boundary of a found (spotted) reservoir and evaluate its characteristics, from the macroscopic pattern point of view. Non seismic techniques manifest themselves in time lapse monitor, description of steam front direction of hydrocarbon recovery and enhancement of productivity during the stage of oilfield development. Under the current circumstances of market economy, it ought to be our common understanding making good use of non seismic techniques in the exploration and development of oil and gas during the entire process and raising exploratory benefit with the cost effective technical advantage.
