THE APPLICATION OF CURVE RECONSTRUCTION TO PREDICTION OF LITHOLOGIC TRAPS IN ORDOS BASIN

In the process of well constrained stochastic inversion,we usually use one single logging curve to reveal the reservoir. This method has difficulties to fully refelct the reservoir charateristics since it uses only one type of curve. In this regard, we proposed in this paper to use a variety of well logs to reconstruct one curve which is closer to the real characteristics of the reservoir. Compared to gamma and neutron gamma logs, the reconstructed curve has a better correlation with the impedance, and the inversed lithologic section is closer to the real. With the data from the area D, we used curve reconstuction inversion technique for reservoir prediction in this paper. Results are much more satisfactory comparing to the conventional lithology inversion, which only uses a single curve.
