FIELD: oil-and-gas industry. ^ SUBSTANCE: invention relates to oil and gas field equipment and is intended for cluster drilling of wildcat and production oil and gas wells. Proposed drilling rig comprises modular units arranged at four parallel guides and in two lines. Additionally, said rig is equipped with set of tanks to keep extra store of water and salt solutions for making drilling and backfilling solutions for well cementing. Said set is arranged in one line with circulation system set and compressor set. Arrangement of said sets may vary in another line. In compliance with first version, behind derrick unit arranged are well cementing unit, pump unit and intake bridge with drilling pipes. In compliance with second version, behind derrick unit arranged are intake bridge with drilling pipes, pump unit and well cementing unit. Note here that unit of electrical equipment is always arranged between well cementing unit and pump unit to allow release excess heat from electrical equipment into pump unit for additional heating of rooms inside rig units. ^ EFFECT: higher efficiency in far north areas. ^ 5 cl, 3 dwg |
