MOBILE COMPLEX FOR OIL PROSPECTING AND PRODUCTION IN COASTAL WATERS

摘要

The technical result of the inventive complex is aimed at improving ecological compatibility and enabling to carry out prospecting and production of oil in sea and lakes coastal waters. It is reached by reducing a mobile complex draught during transportation due to a drilling platform mounting at a drilling site using two self-elevating barges and uniform distribution of the complex equipment weight on shallow-draughted auxiliary barges. Simultaneously, to the lift of assembled drilling platform over water level and orthogonal position of the self-elevating barges stability of the drilling complex to storm loads is increased, wherein decreasing a possibility of containment of water area in bad weather conditions. The ecological compatibility is further improved by discharging boring slurry through a casing string, collecting and slurry discharge to a utilization zone at a separate auxiliary flat-bottomed barge.
