Cluster drilling rigs with a simplified circuit arrangement

摘要

The invention relates to oil and gas equipment and is intended for multiple drilling of exploration and production of oil and gas wells. Installation modules comprises blocks: block cementing block the circulation system, the pump unit 3 with the mud pumps, electrical unit 4, the compressor unit, and the derrick-winch unit receiving bridge with drill pipes and stacks. Blocks modules are arranged in 4 parallel guides with the possibility of horizontal movement, and are arranged in two rows. All units, including the receiving bridge racks and have shelter. In the arrangement of blocks in the two rows of reduced area to service rig and decreased communication links between the modules of blocks, it is possible to install additional blocks and shelter for heating the working zones with decreasing heat loss from the surface of shelters, which increased the efficiency of the plant. 1 bp yl and 5.
