地震勘探技术的发展促进油气勘探新发现——以胜利油田40年地震勘探历程为例

自1927年地震勘探成为一种常规勘探方法以来，地震勘探技术始终处于不断改进之中。特别是在近20年，伴随着电子、计算机、信息等相关学科的飞速发展，地震勘探技术已从模拟发展到数字、从最初的一维发展到现在的三维乃至四维、从单分量接收到多分量接收、从地面勘探到立体勘探、从简单的构造勘探到寻找隐蔽岩性油气藏，如今地震勘探方法不仅可用于勘探复杂地区(领域)的油气藏，而且正向油气的开发领域渗透和拓展。本文以胜利油田40年地震勘探历程为线索，阐述了地震勘探技术发展与油田储量增长的关系，强调为适应勘探目标日趋复杂的形势，促进油气储量的持续增长，必须进一步大力发展地震勘探技术。

Development of seismic exploration promoting new discovery of oil/gas exploration-taking 40 years' history of seismic exploration in Shengli Oilfield as an example.

The seismic exploration has become an ordinary exploration method since 1927 and seismic exploration techniques have always been continuously developed. Especially in recent 20 years,along with the rapid development of relevant disciplines such as electronics , computer and information science , seismic exploration techniques have developed from analogue to numeric,from original 1-D to 3-D even to 4-D, from 1-C to multiple component, from ground exploration to stereo exploration,from simple structural exploration to explore subtle litho logic reservoir. The current seismic exploration methods are not only used for prospecting of reservoirs in complex areas,but also used for infiltrating and expanding toward the new oil/gas development realm. Taking the 40 years' history of seismic exploration in Shengli Oilfield as clues,the paper expounded the relationship between development of seismic exploration techniques and reserve increasing of oilfields and emphasized that it has to further devote major efforts to develop seismic exploration techniques in order to adapt the daily complex situation of explored targets and promote continuously increasing of oil/gas reserves.
