Abstract

In this article we consider the problem of field development on the continental shelf consisting in technological complexity and high capital investments of construction of sea oil and gas constructions in water areas of the Arctic seas. We consider the main advantages of a mine and tunnel way of arrangement of sea oil and gas fields as more effective and economic method of field development. We analyse conditions and possibilities of application of tunneling shield for construction of a tunnel under a seabed. We analyse a possibility of operation of coiled tubing unit for development of wells. We offer the perspective way of construction of underwater oil and gas construction combining building of an underground tunnel under a seabed by means of a tunnelling shield and application in a tunnel of the coiled tubing equipment for well-drilling.
