Техника и технология добычи нефти в осложненных условиях поздней стадии разработки нефтяных месторождений

Reviewed are two groups of problems and methods for their solution, which are common for the late stage of development, which are connected with wax precipitation elimination and peculiarities of producing low rates low profitable well stock, accordingly. Diagram is presented, illustrating the scope of basic dewaxing methods implementation in JSC Tatneft. New technological solution is proposed, providing for fluid withdrawal from the group of wells through one well, into the annulus of which production from other wells is coming by overflow. Reviewed is a ntq technical solution on controlling the work of pumping unit through electric power supply lines, which is applied, for the first time in the world, in JSC Tatneft.
