Buffer plugging systems – advanced direction for natural zeolite application

Influence of flushing fluid on the quality of casing cementation of Romenska deposit group in Dniprovska-Donetska depression has been concidered. Comparative studies of technological characteristics of buffer plugging systems with micro silica additives DBM-1 and natural zeolits DBM-2 and influence of the mix on cements to microstructure formation were carried out. Operational experience and findings obtained by industrial application of buffer plugging systems of different composition during the process of bore holes building at Anastasivska deposit PAT “Ukrnafta” have been presented.
