Oil well blowout control device

Abstract

The invention discloses an oil well blowout control device. The lower part of an adjusting pipe is mounted on a fixing plate; the upper part of the adjusting pipe is provided with a vertical nut; the vertical nut and a vertical screw are in rotary fit; a sleeve is fixed on the upper part of the vertical screw; the axis of the sleeve is vertical to the axis of the vertical screw; the sleeve is sleeved outside a transverse nut; an anti-rotation dowel is mounted between the sleeve and the transverse nut; the transverse nut and a transverse screw are in rotary fit; the transverse screw is connected to the sleeve through an anti-movement dowel; a clamp sleeve is fixed at the left end of the transverse nut; the axis of the clamp sleeve is vertical to the axis of the transverse nut; a variable buckle joint is placed in the clamp sleeve and limited in the clamp sleeve by a limiting dowel; the lower part of the variable buckle joint is connected with a blowout preventer; and the blowout preventer can rotate around the axis of the adjusting pipe, or go up and down or extend inwards and outwards, and can be conveniently and quickly mounted on an oil pipe to blow out on an oil well so as to prevent blowout accidents. Thus, the oil well blowout control device avoids severe economic loss and personal injury caused by blowout, thereby having obvious economic and social benefits.

Description

technical field [0001] The invention is a well head equipment used in the workover operation site of an oil-water well in an oil field, and is an oil well blowout device. Background technique [0002] At present, blowout accidents in oil and gas fields occur from time to time. In order to prevent blowout and prevent blowout during blowout, oil and gas well blowout preventers (also called plug valves) have been developed in oil fields. This blowout preventer can control blowout safely, quickly and effectively. But at present, when a blowout occurs and the blowout preventer needs to be installed on the oil pipe, the blowout preventer is manually transported to the wellhead and connected with the oil pipe in the state of blowout. Delaying the timing of spraying, sometimes the blowout occurs before the blowout preventer is installed, causing serious consequences and major economic losses, and the labor intensity of the workers is high, the danger is high, the safety is poor, and...

Problems solved by technology

But at present, when a blowout occurs and the blowout preventer needs to be installed on the oil pipe, the blowout preventer is manually transported to the wellhead and connected with the oil pipe in the state of blowout. Delaying the timing of spraying, sometimes the blowout occurs before the blowout preventer is installed, causing serious consequences and major economic losses, and the labor intensity of the workers is high, the danger is high, the safety is poor, and there are potential safety hazards.
