Prediction formation anti-drillability parameters by seismic data

Seismic data includes a great deal of formation information,which is picked up by analyzing and processing.Contrast with other data,seismic data not only holds plenty rock information,continuity and low cost,but also is the only data reflects underground stratum information in no exploration well area.This article sets up a VSP system revising model through VSP seismic data and the least double-multiply curved surface fitting principle based on the formation characteristic of Yingmaili Structure of Tarim Oilfield.Furthermore,formation anti-drillability parameters evaluating model is also founded by correlation analysis of regression based on core testing result and interval velocity interval transit time revising value.
