油气藏盖层泥岩的粒度测试及在大杨树盆地中的应用

Grain Testing of Pool Capping-mudstone Andits Application in Dayangshu Basin

介绍了油气藏盖层泥岩的粒度分布测定方法 ,包括所使用的激光粒度仪的特点、所用试剂、测试原理、样品制备及测试结果等。并对激光法粒度测试的精密度及准确度进行了探讨。通过对大杨树盆地盖层泥岩样品的粒度分布测定 ,从而对盖层的微观定量评价提供了依据。

This paper introduced the grain distribution testing method of pool capping mudstone,including the characteristics of the laser grain meter, the reagent,the testing principle, sample preparations and the testing result etc.The precision and accuracy of grain test using laser method were probed. Through testing grain distribution of mudstone of Dayangshu basin,the basis for micro quantification of capping bed was provided.
