The Application of Stochastic Seismic Inversion Method of Geostatistical Inversion in Putaohua X Area

Stochastic seismic inversion is an important part of geostatistical method, and the combination sequence simulation. In process random inversion, firstly, histogram distribution variables counted, variation function calculated, range in different directions determined. Then, for each implementation, traces are synthesized at channel position according to calculated reflection coefficient, error between synthetic original compared, results output after required accuracy reached. Geostatistical can improve vertical horizontal resolution reservoir accurately describe spatial reservoir. Taking Heidimiao oil layer west slope area Daqing Placanticline as example, this paper expounds application work a whole. Combined with attribute analysis well logging curve preprocessing, formed by accurate time-depth calibration other processes sensitivity parameter provide basis optimizing target location area.
