ABSTRACT: In underground oil and gas reserved engineering, coring is an important method
to acquire the stratum information and study the properties of underground rocks. The integrity of
cores is prerequisite for the accuracy of follow-up research. With the analysis of the perniciousness
of the fact that drilling cores are more tending to slake and fracture, it can be found that mud-
stone slaking has adverse effects on such
