However,there are still many interpretation pitfalls in practical seismic interpretation of reef.

Oil/Water mixed layer logging interpretation method in Sabei development area;

Origin of complex oil/field zones and logging interpretation method in the western area of Daqing placanticline;

Study on logging interpretation method of carbonate reservoir in Yemen block 1 wildcat well

A well log interpretation system based on artificial neural networks is designed in this paper.

Stability of inverse convolution calculating method has been resolved by Schroeter、Hollaender and Gringarten which makes it applied in well testing interpretation.

But as for the percolation problem of non-closed boundary, routine method did not work effectively, the Boundary Element Method to study the non-closed boundary mathematical model of well testing interpretation was presented in the paper, which was Laplace transform to the percolation differential equation, the solution in the Laplace.

According to the well testing interpretation, the pays of all the wells in Penglaizhen gas reservoir of Baimamiao are polluted at different levels, the percolation features of the pays are complicated, the permeability near borehole is good and the permeability far from borehole is poor.

Affected by many factors, such as complexity and randomicity of fracture system and well-logging response, the well-logging interpretation of fracture reservoir of carbonate rock is facing a great deal of difficulties.

In well-logging interpretation,oil/gas/water layer identification is virtually pattern identification.
