Annotation:
The choice of the drilling fluid system is particularly important to ensure that the productive reservoirs remain permeable during initial opening. The drilling fluid should also ensure trouble-free drilling of wells. At the Bovanenkovskoye oil and gas-condensate field (OGCF), during wells construction, emergency situations may occur due to the following complications: loss of well wallsstability, sliding and caving, sticking of the drilling tool, packing. In order to prevent emergencies and improve the quality of TP and KhM productive formations by slightly-sloping and horizontal wells, laboratory studies of domestic reagents were carried out and drilling fluids were developed on their basis.
