在南阳凹陷,魏岗-官庄地区的主要构造特征是复杂多样的断鼻断块圈闭,石油大多都分布在鼻状构造的轴部及断层的遮挡部位,而复杂断鼻断块的成像精度对受构造控制油藏的勘探至关重要。本文以魏岗-官庄地区新采集的三维地震资料为主要研究对象,同时收集矿区以往三维地震资料,与本次采集资料进行融合处理,目的是提高该地区复杂断鼻断块的成像精度。通过采用分步、分域的组合去噪、相位校正、子波匹配及五维插值等一系列高精度三维融合处理技术处理后,
In the Nanyang sag, the main structural features of the Weigang-Guanzhuang area are complex and diverse fault-broken fault blocks. Most of the oil is distributed in the shaft part of the nose structure and the occluded part of the fault. The imaging of the complex broken nose block Accuracy is crucial to the exploration of tectonically controlled reservoirs. In this paper, three-dimensional seismic data newly collected in Weigang-Guanzhuang area is taken as the main research object. Meanwhile, the previous three-dimensional seismic data in the mining area are collected and fused with the collected data in order to improve the imaging accuracy of the complex broken nose block in the area. Through the use of a series of high-precision three-dimensional fusion processing technologies, such as step-by-step, combination of domain denoising, phase correction, wavelet matching and five-
