Abstract：Liu Shenheng and Zhu Chunsheng. The application of Wiener filtering in mufti-in- terface gravimetric interpretation. OGP,1993，28(6):714-720 There are four density interfaces in CCL-SZ area in the Songliao basin. The density of shallow formations (Cretaceous system)shows dominant vertical varia- tion;and the density of deep formations (Jurassic system, basement) mainly exhibits lateral variation. Hence gravimetric data interpretation in this area must be made using the inversion of multiple density interfaces. The comprehensive interpretation of multiple density interfaces in this area was done by making full use of seismic， drilling, geological, magnetic and gravimetric data. We first separated out the gravity anomaly of Jurassic system and the basement by performing the Wiener filtering，then conducted interactive section fitting calcu- lation,finally combined sectional inversion result with planar inversion result to ob- tain the forms of Jurassic system interface and the basement. Depth error may be less than 10%.
