Abstract
The article briefly describes some features of the geological structure of a complex development formation - the B10 layer of the Khamakinsky horizon. The B10 layer of the Khamakinsky horizon has the following specific features that negatively affect the state of the reservoir properties of the layer: hydrophobicity, anhydritization, susceptibility to aggression from aqueous solutions of well killing, bituminization.
The rationale for conducting geological and technical activities is presented, taking into account complicating factors and reservoir characteristics. The article shows that the technological efficiency of the proposed technologies and technical solutions is associated with the use of the most optimal killing fluids for the B10 formation (in workover operations) on a hydrocarbon basis (commercial oil, reverse water-oil emulsion). The technology of gas-dynamic rupture of the B10 formation is presented, which has demonstrated its effectiveness during experimental work on three wells in the study oil field. The complex effect consists of creating artificial fracturing and local heating of the well's Bottomhole zone, which made it possible to obtain an increase in oil flow rate from 3.5 to 5 tons/day and increase the productivity coefficient by 15 %.
