【摘要】：長昌凹陷斷裂系統(tǒng)復(fù)雜且密集,剖面上斷層產(chǎn)狀相似,存在解釋困難、組合關(guān)系難以確定等難題,應(yīng)用常規(guī)地震解釋方法容易產(chǎn)生錯(cuò)亂,降低解釋效率,為斷層平面組合帶來困難,嚴(yán)重影響構(gòu)造圈閉搜索和油氣運(yùn)移研究。針對(duì)研究區(qū)存在的問題,基于相干技術(shù),綜合應(yīng)用時(shí)間相干切片平面-剖面聯(lián)合解釋斷層,沿層相干切片指導(dǎo)斷層組合,斷距定量分析驗(yàn)證斷層平面組合,三維可視化技術(shù)驗(yàn)證斷層空間組合4種技術(shù)的優(yōu)勢開展精細(xì)斷裂解釋。實(shí)際應(yīng)用結(jié)果表明,在斷裂復(fù)雜且密集發(fā)育區(qū),運(yùn)用綜合解釋方法能夠克服常規(guī)解釋方法的不足,極大地提高了復(fù)雜密集斷裂解釋的效率和準(zhǔn)確性。
[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.
