Application of Seismic Attributes in Geo-steering of Horizontal Well
摘要
Abstract
Horizontal well logging while drilling is a multi-disciplinary integrated technology.In the Sichuan Basin, due to its complex stratigraphic structure, large lateral variation of reservoirs and strong heterogeneity, conventional logging data cannot provide support for the geo-steering.This paper studies the application of seismic properties in geo-steering in the complex stratigraphic of the Sichuan Basin.Seismic attributes refer to the geometrical and kinematic characteristics of seismic waves derived from pre-stack or post-stack seismic data and derived from mathematical transformations. Which can reflect the physical characteristics of rock more realistically, and can also be used to describe the geometry, structural features and reservoir outline of the reservoir.Seismic attributes contain a wealth of geological information, especially in recent years, popular attribute extraction techniques such as curvature bodies, ant bodies, etc., can well identify small faults and fractures (holes) that are difficult to distinguish from logging data.These techniques not only predict the reservoir development zone, but also provide a basis for predicting drilling risks.The practical application proves that seismic attribute extraction technology can provide technical support for on-site geo-steering decision-making, meanwhile it plays an active role in improving drilling rate and reducing drilling risk, which is worthy of promotion.关键词
