VSP技术在河南油田油气勘探中的应用

VSP Techniques and Application in Exploration in Henan Oilfield

垂直地震剖面法(VSP)勘探技术,是地震剖面与地质层位之间的桥梁,能为利用地面地震反射信息进行构造精细解释、储层横向预测和油藏描述提供可靠的资料依据。阐述了VSP技术的基本原理、采集方法和在油气勘探中的作用。介绍了VSP技术在河南油田油气勘探中提供时深参数、层位标定和研究井旁构造方面的应用情况。分析了存在的问题,并提出下步工作的建议。

Vertical seismic profile technique,a bridge connecting seismic section and geologic horizons,can provide reliable data for fine interpretation of structures,lateral prediction of reservoirs and reservoir characterization with surface seismic reflection information.This paper discusses the basic principles of VSP technique,seismic acquisition methods and its functions in exploration;and introduces its applications in providing time-depth parameters,hori-zon calibration and study of near -wellbore structure in Henan oilfield.The problems currently existed are ana-lyzed and some proposals are presented in this paper.
