【摘要】：长昌凹陷断裂系统复杂且密集,剖面上断层产状相似,存在解释困难、组合关系难以确定等难题,应用常规地震解释方法容易产生错乱,降低解释效率,为断层平面组合带来困难,严重影响构造圈闭搜索和油气运移研究。针对研究区存在的问题,基于相干技术,综合应用时间相干切片平面-剖面联合解释断层,沿层相干切片指导断层组合,断距定量分析验证断层平面组合,三维可视化技术验证断层空间组合4种技术的优势开展精细断裂解释。实际应用结果表明,在断裂复杂且密集发育区,运用综合解释方法能够克服常规解释方法的不足,极大地提高了复杂密集断裂解释的效率和准确性。
[Abstract]:Chang Chang sag fault system is complex and intensive, profile similar fault occurrence, are hard to explain, it is difficult to determine the combination relations and other problems, the application of conventional seismic interpretation methods are prone to confusion, reduce the interpretation efficiency, bring some difficulties for the combination of fault plane, migration of oil and gas traps in search and seriously affect the existing problems in the research area. Based on the comprehensive application of technology, coherent, coherent time slice plane - section joint fault, lithologic body guide fault combination analysis of broken fault plane from the combination of quantitative verification, 3D visualization technology to verify the fault space combination of the advantages of these 4 technologies to carry out fine fault interpretation. The practical results show that the fracture in the complex and intensive development zone using the comprehensive interpretation method, insufficient to overcome the conventional interpretation method, which greatly improves the efficiency and accuracy of interpretation of complex fracture.
