Investigation on equivalent water depth truncated model test design of a deepwater semi-submersible platform

Several factors were taken into consideration in the computation method, including the general characteristics of the typhoon wave, the equivalent water depth, wave refraction in shallow water region,the energy distribution characte.

The formation pressure gradient curve in the same depth of logging is computed by equivalent depth method.

This paper, based on the equivalent depth method's basic principle, focuses on discussing about setting up the normal compaction trend curve for carbonate rock profile, and predicts the formation pore pressure of the carbonate rock profile's fracture pore reservoir of Feixianguan interval on the east of SiChuan by making use of the setting up of normal compaction trend function of.

From the fundamental principle of equivalent depth method,construction of a normal compaction trend line for sand slime is discussed in the paper on the basis of logging data.

This paper aims at the relative difficult problem predicting the formation pore pressure of carbonate rock, starts with the key technology of equivalent-depth method to calculate formation pore pressure, and focuses on discussing about setting up the normal compaction trend curve for carbonate rock profile by using apparent logging data of mudstone formation, and.
