초록 ▼

New and improved techniques, systems and equipment for the practical underground mining of petroleum from both virgin and depleted oil fields under certain geological conditions, are described. A method of drilling relatively small diameter, drainage-type oil wells using a fluid and cutting control assembly from within an access underground drilled tunnel, is provided. The fluid and cutting control assembly facilitates the safe underground drilling and installation of the small diameter, drainage-type oil wells which can be operated either under the natural pressures occurring in the geological strata, as gravity drain wells or by suitable secondary treatment measures artificially pressurized to facilitate drainage of oil from oil bearing strata into which such wells are drilled. Techniques and equipment to facilitate the safe drilling of such wells, placing them into production and thereafter controlling operation of the mine workings in a safe and reliable manner, is described, together with the control system, sensors and other equipment required for safe installation and operation of an underground petroleum mine.

The method of drilling a relatively small diameter gravity-type drain oil well using a fluid and cutting control assembly comprising a stop valve mounted on a pipe casement for securement to a firmly anchored collar pipe providing the outer liner for an access opening to a gravity-type drain oil well, said gate valve and pipe casement having an inside diameter opening with said gate valve in the open condition sufficient to accommodate the outside diameter of gravity-type drain oil well production conductor pipe and drill string-together with appended stop valves, couplings and the like, upper and lower blow-out preventers secured to said casement below said stop valve and having internal diameters sufficient to accommodate the external diameter of the gravity-type drain oil well production conductor pipe and drill string fittings, an upper drain vent control valve connected to a first drain vent branch pipeline and to said casement between the stop valve and the upper blow-out preventer and a lower drain vent control valve connected to a second drain vent branch pipeline and to the casement intermediate the upper and lower blow-out preventers, and wherein the assembly is secured to an annular collar mounted in and surrounding a relatively small diameter access opening for a gravity-type oil drain well to be drilled into the overlying roof of a tunnel cut into a competent rock zone below oil well sands containing unrecovered oil, inserting the drill bit and supporting drill string through the opened lower and upper blow-out preventers and through the opened stop valve, drilling the small diamter gravity-type oil drain well upwardly through the overlying competent rock roof of the tunnel and into the oil bearing sand zone to a desired depth while supplying cutting fluid to the drill bit under pressure upwardly through the drill string, maintaining the upper and lower blow-out preventers tightened down on the exterior of the drill string to only a slide fit during drilling and drawing off used cutting fluid and entrained cuttings through the upper and lower drain vent control valves and connected branch drain pipelines for removal to the surface.
