近十多年来, 超压成因研究在国际上取得了重要进展, 主要表现在5 个方面. 1
将超压按照成因分为5 种类型: 不均衡压实, 流体膨胀, 成岩作用, 构造挤压, 压力传递; …

Much progress in the studies on the causes of overpressuring has been made during the
past decades, which is summarized and discussed in this article.(1) In terms of the causes …

Practically, the rock bulk density is measured either through logging while drilling tools or
wireline logging techniques. However, these measurements are not always available, which …

The origins of overpressure in the central Xihu depression have been accepted to result
from disequilibrium compaction and hydrocarbon generation. This study uses organic matter …

Much progress in the studies on overpressuring mechanisms has been made during the
past one to two decades.(1) The causes of overpressure are divided into five categories …

Conventionally, pore pressure predictions from the drilling parameters have the advantage
of estimating the formation pressure at the bit at relatively low cost. The limitations on the …

As one of the most important elastic parameters in seismic exploration, density plays an
important role in lithology identification and hydrocarbon indicator. Based on the …

Accurate real-time estimation of pore pressure is essential for the geomechanical analysis of
wellbore stability. Conventional empirical methods may find it difficult to capture pore …

One of the complexities of geomechanical study is in the classification of rock's properties
and overpressured intervals—a knowledge which is not only essential for well safety and …

Because of porosity and mineralogy disparity, rocks have a broad range of bulk densities, a
critical property that has an important role in rock characterization. Practically, the density of …
