Some aspects of development and study of polymer-potassium drilling mud for sidetracking
R.M. Zeynalov PhD in Tech. Sc. - “Oil-Gas Scientific Research Project” InstituteAs the great majority of the fields in Republic are being at the late stage of exploration, the sidetracking is a hot topic. Based on carried out studies it was revealed that the sidetracking is cost-effective, due to which the field performance dramatically improves. Advanced technologies using up-to-date drilling mud types are applied in sidetracking experience, but the improvement of their recipes for complication conditions is of great importance.
The paper presents some aspects of development and investigation of polymer-potassium drilling mud for sidetracking. For this purpose, special attention is paid to the structure-forming properties of applied clay types, particularly the colloidity rate for clay and mud plasticity.
The dependence has been obtained based on conducted studies. It was defined that in high colloidity rates the plasticity increases, and the permeability of mud cake reduces as well.
Polymer-potassium drilling mud is characterized with high inhibiting properties and the mud cake has minimum thickness and less permeability.
Developed drilling mud may intensively transport drilled particles of subsurface rocks to the wellhead of lateral holes.
