The methods to identify the types of reservoir by using such parameters as dipmeter, long space sonic, resistivity, porosity and alteration factor are studied.
探索了用地层倾角、长源距声波、电阻率、三孔隙度及蚀变系数识别储集空间类型以及对储层分类的方法；

The log is made from resistivity, density, neutron, and sonic log data and shows porosity, secondary porosity, grain density, fluid analysis, water saturation, and formation analysis.
The regression analysis shows that the velocities are liner relationship related to porosity and clay content. Using such regression formula to sonic logging data indic…
