摘要/Abstract

摘要： 基岩潜山风化壳是油气勘探重要领域，但基岩潜山一般埋藏较深，地表、地下构造复杂，导致地震成像困难，地震振幅难以保真，风化淋滤带储层预测难度大。为了准确刻画基岩潜山风化淋滤带储层，采用从近地表出发的整体速度建模技术和保真叠前深度偏移技术，提高了复杂构造区地震资料成像准确性和保幅效果；针对基岩潜山风化淋滤带的分层特征，将地震资料和地质资料相结合，建立了潜山储层内幕分层结构；应用了相干体和蚂蚁追踪等技术识别出裂缝分布规律，再结合地震振幅的分类特征，获得了基岩潜山内幕的有效储层厚度。在酒西盆地青西凹陷鸭儿峡潜山的实际应用效果表明：根据油藏开发情况圈定出的高产油藏区，与该方法预测出的风化淋滤带储层厚度对应良好。该方法可为基岩潜山内幕储层目标刻画提供支撑手段。

Abstract: The weathering crust of bedrock buried hill is an important field of oil and gas exploration. However, because of the deep buried depth,the complex surface and underground structure,it is difficult to obtain seismic imaging and the seismic amplitude is hard to be preserved. Moreover,it is difficult to predict the reservoir in weathering and leaching zone. In order to accurately depict the reservoir in weathering and leaching zone of bedrock buried hill,the velocity modeling technology from near-surface and amplitude-preserved pre-stack depth migration technology were used to improve the seismic imaging accuracy and amplitude preservation effect of complex structural area. Based on the layered characteristics of weathering and leaching zone of bedrock buried hill,combined seismic data with geological data,the internal layered structure of buried hill reservoir was established. The fracture distribution law was identified by using coherence cube and ant tracking technology,then combined with the classification characteristics of seismic amplitude,the effective thickness prediction of inner bedrock buried hill was carried out. The actual application in Ya'erxia buried hill proved that the high-yield reservoir area delineated according to reservoir development made a good match with the reservoir thickness prediction of the weathering and leaching zone by this method. This method can provide effective support for the characterization of inner reservoir targets in bedrock buried hill.

Key words: amplitude-preserved pre-stack depth migration, bedrock buried hill, weathering and leaching zone, depth domain interpretation, reservoir prediction, fracture prediction
