Abstract

A thermal-mining method of oil production is effected by digging a combination of underground workings and at least one working tunnel and by drilling injection and producing wells from said working tunnel. Then a heat carrier is forced into the oil-bearing bed for heating it to a temperature sufficient for the oil to acquire the necessary fluidity. The heat carrier is forced into the oil-bearing bed through injection wells at time intervals t.sub.1 found from an appropriate relation. The oil is withdrawn from the oil-bearing bed through the producing wells at time intervals t.sub.3 in which the time interval t.sub.1 of heat carrier injection into the injection wells is divisible by the time interval t.sub.3 of oil withdrawal from the producing wells, the multiplicity factor being equal to n=(t.sub.1 /t.sub.3).gtoreq.60.
