The physical model is the same as what was used in ref. [1] and the two dimensions Fast Fourier Transformation algorithm (FFT) is adopted. The evaluation method and program which are used to calculate the full waveform of acoustic pressure in the cylindrical multilayer quasi elastical media is given.The numerical evaluation of the acoustic pressure waveform has been done for many kinds of parameters. The effect of the water layer between two solid media on the waveform is analysed, particularly for the changes of the earlest arrived wave when the cementing interface between casing and cement or cement and formation is broken and there is water between them. The results show that the amplitudes of P and S refracted arrival waves from casing are reduced obviosly when there is water layer between two solid media; and the reflected waves from the interface between solid and fluid is an important mechanism to affect the characters of the esrlest arrived wave.

Rock creep progreeses through three stages, i. e. the stage of initial transitionalcreep, the stage of steady--state or pseudoviscous creep and the stage of acceleratedcreep. The stage of accelerated creep is the closest to the failure point of the rock,so the rock behaviours in this stage may be regarded as an indication of rock fai-lure. The appearance of microfractures is a diagnostic criterion of this stage. If mi-crofractures are regarded as an indication of an earthquake, it is suitable to findout the...

Rock creep progreeses through three stages, i. e. the stage of initial transitionalcreep, the stage of steady--state or pseudoviscous creep and the stage of acceleratedcreep. The stage of accelerated creep is the closest to the failure point of the rock,so the rock behaviours in this stage may be regarded as an indication of rock fai-lure. The appearance of microfractures is a diagnostic criterion of this stage. If mi-crofractures are regarded as an indication of an earthquake, it is suitable to findout the relationship between microfractures and an earthquake. Microfractures canbe cemented after a long period of stability. Three manners of cementation are su-ggested in the paper: healing, welding and filling. For the first manner, the ceme- nting minerals filling, the microfractures are the same as the parent crystalsand both take the same crystallographic orientation. For the second manner, thecementing minerals are the same as the parent crystals but both take different cry-ystallographic orientations. As to the third manner, the cementing minerals are di-fferent from the parent crystals. The strengths of cemention of the three mannerof cementation are different. The cementation strength of the healing manner isstronger, while that of the filling manner is weaker. Microfractures and their cemen-tation are indications of rock failure. they call probably be regarded as indicationsof an earthquake, and thus may serve earthquake prediction.

本文探讨岩石第三蠕变阶段(加速蠕变阶段)的显微构造特征——微裂隙。在天然岩石漫长的蠕变过程中,加速蠕变阶段预示着破裂将至,而前两个蠕变阶段则距破裂还很遥远、所以微裂隙的大量出现,将会使岩石发生总体破裂,从而导致地震的发生。本文还探讨了地质作用平静时,微裂隙可能以三种方式固结。固结后的岩石应是一种新岩石,不再继承已经发生的蠕变过程、而是重新开始自己的蠕变过程。

In this paper, the reservoir sandstones of Shuanghe oilfield has been classified and evaluated on the basis of a large quantity of data of mercury injection capillary curves and petrophysical properties of rocks. In the meantime the principle and research method of pore geometry of rocks have been used. The average pore-throat size of rocks is the most important parameter among all of these data. There is a mathemetical interrelation between the average pore-throat size and other parameters of rocks. The correlation between petrologic properties and the pore structure of sandstones has been studied, combining with thin sections appraised. Finally, we obtain a conclusion that pore size distribution of rocks is principally affected by sandstone grain size and cementing materials and types. So the good reservoir rocks can be further found in the favourable sedimentary facies.
