Comparison of D-T and D-D accelerator investigation characteristics in pulsed neutron porosity logging while drilling

四川盆地须家河组低孔致密砂岩孔隙度测井解释研究声速测井确定的孔隙度

Porosity logging interpretation of low-porosity compact sandstone of Upper Triassic Xujiahe Formation in Sichuan Basin , China

本文介绍一种根据钻井中已知岩性和相应的声速测井求得的层速度，用概率论中的具叶斯公式算出不同井深各层速度值对应的泥岩比值的方法。

Based on the known interval velocities obtained from the lithologic log and sonic log , this paper presents a way of estimating the sand-shale ratio corresponding to the interval velocity at different well depths by using the Bayes formula of the probability theory .

其后，详细地分析了单发双收声速测井资料受井径影响的物理机制，在此基础上提出了相应的校正公式及校正图板。

Then the authors analyse the physical mechanism of how borehole diameter affects the velocity logging data which are collected by using the logger that has one transmitter and two receivers . Then corresponding correction formula and correction chart are given in the paper .

声速测井在煤田地质勘探中的应用根据200多煤层次的注入/压降试井数据以及多年来的煤田地质勘探资料，简要总结了我国煤层气储层基本特点；

Based on the analysis and test data available from over 200 CBM wells drilled in recent ten years , as well as the geological information from the coal exploration performed in last thirty years , the basic characteristics of CBM reservoirs in China have been summarized .

在象黄骅坳陷孔店南区这样的声速测井测量井段比较深，因而正常压实段较短的地区，可以在小范围内综合几口井的资料来确定正常趋势。

In such areas as southern Kongdian , Huanghua Depression , where sonic log is usually started from a deeper depth , and therefore the normally compacted sections are shorter , the data from several wells can be synthesized to determine the normally compacting trend of mudstone .

本文提出一种地震声速与测井声速对比勘探石油的设想。此法拟利用垂直地面方向的纵波声速，即纵向地震声速与测井纵波声速。

A now idea is proposed to prospect petroleum by comparison of seismic sonic velocity and well logging sonic velocity .

位于潜水面以下的诸地层中，其纵向地震声速明显地小于测井纵波声速的地层应是油气层，而具有相同纵向地震声速的连续延伸区域应属于同一圈闭，其中贮有油气。

Under the underground water level , the formations in which the vertical seismic sonic velocity is smaller than the well logging sonic velocity may be reserviors .
