Abstract
The utility model relates to a casing head rescue spray device used for rescue in oil-water well blowout, which is especially applicable to emergency rescue of old well blowout when casing head or casing head is damaged. The utility model casing head rescue spray device comprises a lubricator, a blowout preventer and a large four-way flange connected from top to bottom in turn. The utility model is characterized in that a cut thread device is arranged below the large four-way flange. Either a bushing taper tap cut thread device or a bushing box tap cut thread device can be used as the cut thread device, the material hardness of cut thread device should exceed material hardness of bushing. If casing head of well head is damaged severely, the cut thread device can be changed to the short nylon seal section, the short nylon seal section is pressed into the casing head by the rescue spray device to close down the well.
Description
Technical field
The utility model relates to a kind of casing head blowout control device, speedily carries out rescue work when this device is mainly used in the oil-water well blowout, is a kind of oil well head emergency tool of special use.
Background technology
At present, the down-hole construction operation is carried out in the oil field, construction team is not equipped with corresponding well head blowout control equipment, can not satisfy the well control needs, the old well that especially has only casing head or casing head to damage is carrying out that gas blowout accident often takes place when operation or wellhead equipment are changed, in addition, the long stolen generation that also may cause gas blowout accident of well head that stops well has only the specialist tools of utilization that the well head damaged location is implemented effective shutoff and set up the kill-job passage, could prevent and treat this type of gas blowout accident timely and effectively.
Summary of the invention
The purpose of this utility model is to provide a kind of effective casing head blowout control device.To satisfy the security needs in speedily carrying out rescue work of above-mentioned well head in construction and blowout.
The utility model adopts following technical scheme: a kind of casing head blowout control device from top to bottom is formed by connecting by lubricator, preventer and big four flange successively, it is characterized in that in big four flange bottom sleeve pipe thread making device being housed.
When using casing head blowout control device of the present utility model, at first above-mentioned casing head blowout control device is connected, with crane gear this device is sling then, and it is placed in the middle with well head, guide the gas stream that sprays in the well into top by blooie pipe simultaneously, and the casing head blowout control device is fixed with earth anchor, so that well head operation, utilize the own wt of blowout control device to add on the casing head that is pressed in well head, by afterburning thick stick rotation blowout control device, utilize sleeve pipe thread making device thread making on the casing head exposed end of well head of its underpart.Sleeve pipe thread making device can be selected sleeve pipe die nipple thread making device for use, also can select sleeve pipe female coupling tap thread making device for use, specifically decides according to well head sleeve pipe situation, and the material hardness of thread making device should be greater than the material hardness of sleeve pipe.Close preventer behind the thread making, set up extruding well system, then finish and rob the spray operation.The diameter of above-mentioned thread making device should be complementary with the diameter of well head casing head.
Casing head well damage as if above-mentioned well head can not satisfy the thread making condition, then can change the thread making device of blowout control device bottom into the sealed nylon pipe nipple, the sealed nylon pipe nipple is added by blowout control device be pressed into casing head, realizes the kill-job sealing.The diameter of above-mentioned sealed nylon pipe nipple should be complementary with the diameter of well head casing head.
