Rješavanje hidrauličkih problema pri cementiranju međukolone u uvjetima složenog gubljenja cirkulacije

Experience in studying the phenomena of the loss of circulation of drilling fluids and cement slurry in the Dinaride region, as well as its prevention, is discussed. Direct hydraulic junction between the sea and the deep caverns and splits has been determined. In drilled caverns, circulation of water has been observed, decreasing the stability of the hole and diluting the cement slurry. As an example, the Pu-1 well has been investigated in order to lacate the spot of liquid loss and to establish a high-quality cementing operation for the technical casing strings under the conditions described.
