产层特性与完井方式的选择

Pay Zone Properties and the Selection of Well Completion Techniques

过对产层特性、产层井眼周围的应力分布及其与产层特性之间的关系进行分析，指出产层特性决定了产层井眼周围的应力分布状态，因此成为选择完井方式的决定性因素。同时指出用所谓“Ｃ”公式判断产层的坚固程度，并据此选择完井方式是不当的。

Through an analysis of pay zone properties, stress distribution around wellbore and the relationship between stress distribution and pay zone properties, it is pointed out in this paper that pay zone properties determine the stress distribution around wellbore. And therefore, pay zone properties is the principal consideration in selecting well completion techniques. It is also pointed out that it is not appropriate to use the compressive strength of pay zone rock to select well completion techniques.
