In-situ casting of well equipment

For producing between the oil well and is at strata on the sealing of liquid, a building filling the underground hole is difficult to achieve, the invention provides a oil well and method for pouring method, wherein a can be expanded the metal when the concrete, the method comprising the following steps: The is placed metal integrated an oil well chamber; That the body is to achieve is higher than the metal melting of a temperature; Integrated cooling device is a lower than the melting part of the metal, so that the metal body is a coagulate in the chamber.
