The development of a new drilling mud for well drilling in abnormally low formation pressures
Kh.S. TatliyevThe article shows that one of the problematic complications in well drilling in the Republic is the drilling mud loss. For water-loss control the authors have developed a new high efficient agent - modified natrium-naphtanate lignosulphate, which thins up and stabilizes the drilling mud. The application of this agent makes possible decreasing the drilling mud density to 300 kg/m3. The ratio and firmness of the drilling mud have been investigated on the basis of the new natrium-naphtanate lignosulphate agent. It was shown that the drilling mud on the basis of natrium-naphtanate lignosulphate has high inhibitor property in regard to the easily dispersing and swelling clay rocks.
