Using Reassemble Interval Acoustic Transit Time to Predict Formation Pressure
Pengbo Liu · Xinjiang shiyou dizhi · 2007
The normalization of logs in the same pressure area is made with the reassemble interval acoustic transit time logs from several wells. Some given formation pressures from partial wells are used to calculate the coefficients in Fillippone's formula and well pressures in studied area, and the planned well pressure is calculated by range weighted method. The proposed method for pressure calculation has been compiled into interactive software by using VC program. The pressure prediction of planned well in BS35 area is conducted, indicating that the software are quite helpful to the prediction of formation pressure in the area.
