TECHNOLOGIES OF BLOCKING THE ZONES OF FLUSHING FLUID LOSS BY LOCAL WELL CASING EQUIPMENT

 

Annotation. Blocking of the absorption zones of flushing fluid consists of pumping highly viscous packs; installing cement bridges; reducing the pressure on the well walls; isolating the formation absorbing the fluid from the well by plugging the channels with cement plugging mortars or special materials; selecting the formulation of the flushing fluid, etc. The article deals with the technologies of blocking the flushing fluid absorption zones by local well casing equipment. Two technologies with or without diameter reduction in vertical, directional and horizontal wells drilled with drill bits of 215.9 mm diameter are singled out. An indicator line diagram is constructed to investigate absorption zones, highlighting the area of application of local well casing equipment. 

Keywords: absorption, local well casing, profile shutter, blocking of trouble zone.
