TECHNIQUE AND TECHNOLOGY OF OIL PRODUCTION IN COMPLEX CONDITIONS OF THE LATE-STAGE OF THE OIL-FIELD DEVELOPMENT

Reviewed are two groups of problems and methods for their solution, wh ich 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, il lustrating the scope of basic dewaxing methods implementation in JSC ' 'Tatneft''. New technological solution is proposed, providing for flui d withdrawal from the group of wells through one well, into the annulu s of which production from other wells is coming by overflow. Reviewed is a ntq technical solution on controlling the work of pumping unit t hrough electric power supply lines, which is applied, for the first ti me in the world, in JSC ''Tatneft''.
