摘要： 受地震资料横向分辨率的限制以及偏移成像不够精确的影响, 高角度地层的构造解释存在较大的不确定性, 这种不确定性直接影响后期对构造的落实、沉积和成藏的研究。以珠江口盆地东部惠州地区HZ25-7文昌组地层圈闭为例, 通过理论推导、模型正演、地震重处理和倾斜电缆地震重采集, 从各种途径提高三维地震横向分辨率, 并在此基础上确定解释方案, 得到了文昌组沉积时期沟隆相间的古地貌图; 结合该地区地质背景和对已有钻井的分析, 结合物源方向, 初步分析了该构造的沉积和成藏特征以及有利的勘探方向。

关键词: 横向分辨率, 偏移成像, 模型正演, 倾斜电缆采集

Abstract: Limited by lateral seismic resolution and the quality of migration imaging, the structure interpretation of high-angle strata directly affected the follow-up research of the structure, deposition and reservoir evaluation. In this paper, the HZ25-7 stratigraphic trap in the Huizhou Depression of eastern Pearl River Mouth Basin was used as an example to study the improvement of lateral seismic resolution through theoretical derivation, forward modeling, re-processing and re-acquisition of 3D seismic data. Based on the research, interpretations of paleogeomorphogloic map, combined with the geological background and drilled wells, were used to analyze the deposition system and reservoir in this area.

Key words: lateral seismic resolution, migration imaging, forward modeling, lean cable acquisition
