As described in SY/T 5336-2006 5.3.2.1.1.8 g, pore volume should be close with reference cell volume, but works as pore-body
When amassing very little, reference cell volume is difficult to and pore volume approximation；
Utilize the essence of Boyle law dual chamber method measurement core porosity, i.e. measure the pressure being caused by rock pore volume and become
Changing, pore volume is more big, and the pressure change being caused by it is bigger；Getting over hour at pore volume relative to reference cell, pressure changes then
Less, the change of error relative pressure is bigger, bigger on measurement result impact.
To sum up, the Boyle law dual chamber method (rock sample cup) that SY/T 5336-2006 recommends measures particle volume, is measuring
During low-porosity sample such as shale (porosity is often 0～2%), measuring result error is relatively big, have impact on follow-up test and research.
