【摘要】 阐述了测井约束地震反演研究的必要性、技术内涵及研究思路,回顾了测井约束地震反演技术的发展历程,比较了三种非线性测井约束地震反演方法的优缺点.小波变换以其独特的变时窗特性,在测井约束地震反演技术发展中潜力较大,值得深入研究.同时对测井约束地震反演技术的研究现状做了小结,指出当前的研究对象已转向了复杂地质体,特别是海相碳酸盐岩复杂地质体,由于海相和陆相油气田存在许多不同之处,所以测井约束地震反演技术将面临巨大的机遇和挑战.最后,指出了测井约束地震反演技术的发展方向.更多还原

【Abstract】 Necessity, technique meaning, and thoughts of well log constrained seismic inversion are expounded in this paper. The developing course of well log constrained seismic inversion is reviewed. After three nonlinear methods of well log constrained seismic inversion are compared, the result is that wavelet transform has more potential and deserves to lucubrate. Present research situation of well log constrained seismic is summarized briefly, and it can be pointed out that our research object is turned to marine complex carbonatite geologic body. The technique will meet good opportunity and challenge because continental and marine oil and gas field differ in many ways. Finally, the developing direction of well log constrained seismic inversion is pointed out.更多还原
