Appfication and Study on Compound Solid-free Drilling Fluid of CL Plant Glue for Coring Drilfing in Complicated Formation

Abstract:

To meet the demand of wire-line coring drilling in complicated formation, compound solid-free drilling fluid of CL plant glue was compounded and used instead of drilling mud with the property of wall protection and leaking stoppage. The paper detailed the formula, compounding technology, performance index test and evaluation, borehole wall protection mechanism and application effect.
