2通过罗67井岩芯的系统研究表明，泥岩的横波和纵波速度随温度增大而降低，一定温度条件下随为压力而增大；泥岩裂缝的测井曲线一般表现为高电阻率、负自然电位异常、低声波时差，利用该规律可以半量定地识别划分泥岩裂缝储层特征，为解决不同度数据的相互匹配这一重点和难点问题提供了思路和方法。

The growth relationship between spectrum parameter and fetch were studied, from which three parameters and overshot phenomenon that appears during wind wave spectra developing were tested, and an equation describing the growth of three-parameter spectra with wind wave was obtained With the equation, the spectra of wind waves were obtained at zero-dimensional fetches of 300, 500, 2000, 5500, 10000, and 15000, and the overshot was described more clearly. However, the overshot does not exist in the whole process of wind wave spectrum development as stated previously by Hasselmann, but in the early stage of the development only, extenuates with wave growth and then disappears when the wave fully grows.

First the relationship of shoaling coefficient and relative water depth in regular and irregular wave fields has been analyzed. The experimental result shows that shoaling wave height decreases at first then increases until wave breaking. The broken wave height of regular waves is smaller than irregular waves with same wave steepness and relative water depth.
