Abstract
The utility model provides a pumping rod type overflow controller, for raising the pumping rod to preventing the overflow of the crude petroleum from the wellhead when the oil well is maintained. The pumping rod type overflow controller comprises a tube body and a connecting rod. A plugging head is fixed in the lower of the tube body, wherein the plugging head is in column shape and the centre hole of the plugging head is in cone shape. A connecting rod is arranged in the rod, two ends of the connecting rod are arranged with outside thread, a cylinder is arranged on the upper of the connecting rod and the lower of the outside thread. The lower of the cylinder of the connecting rod has a cone, and the steepness of the cone is same to that of the centre hole of the plugging head. A cylindrical form rod is arranged on the lower of the connecting rod cone. The controller can rapidly control the wellhead overflow and blowout, to avoid various safety accidents.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, particularly during workover, on carry the special-purpose blowout preventer fast of the excessive generation of sucker rod prevention well head crude oil.
Background technology
During the oilfield maintenance, need to carry sucker rod.When down-hole pressure was big, crude oil can overflow from outer wellhead in the well.If that crude oil takes place when carrying sucker rod is excessive last, pollute the environment, cause crude oil to run off.
At present, excessive in order to reduce crude oil, former well wellhead assembly can only be installed, utilize former well wellhead assembly control crude oil excessive.It is longer that the former well wellhead assembly time is installed, and needs crane gear to assist; The excessive time-consuming of control well head is long, increases individual labor intensity.
The utility model content
The purpose of this utility model is: a kind of oil pumping rod-type overflow controller is provided, is installed on the wellhead flange, can carry in the sucker rod process last, it is excessive to realize controlling crude oil fast at any time, avoids the various security incidents by the excessive initiation of crude oil.
The technical solution adopted in the utility model is: oil pumping rod-type overflow controller, mainly to form by body and connecting rod, and body is cylindric, there is external screw thread at the body two ends, body can be connected on the well head.It is characterized in that: be fixed with block head in the lower end of body, block head is the cylinder bodily form, and the block head centre bore is taper, and relief hole is arranged on block head, and relief hole is in the outside of conical central hole.When the needs pressure release, can down-hole pressure be released by relief hole.
Connecting rod is arranged in body.There is external screw thread at the two ends of connecting rod, and external screw thread that can be by two ends is connected connector in the middle of the sucker rod.Cylinder is arranged at the bottom at the connecting rod upper external screw thread, and cylinder physical efficiency seat is on the top of block head.Cone is arranged at the cylinder bottom at connecting rod, and the gradient of cone is identical with the gradient of block head centre bore.In the bottom of connecting rod cone the cylindrical body of rod is arranged.
Described block head centre bore is the square taper; The cone of described connecting rod is square cone.
Relief hole on the described block head is four, is evenly distributed on the block head.
Oil pumping rod-type overflow controller method of operating: consult Fig. 1.Last when proposing the sucker rod workover treatment such as well head excessive phenomenon takes place, immediately body 1 is connected on the well head; There is external screw thread that connecting rod 2 is connected in the well on the sucker rod at the two ends that utilize connecting rod 2.After connecting the cone 2.2 of connector 2 is inserted in the centre bore 1.2 of body 1 block head, crude oil is excessive in the energy plugged well.
The beneficial effects of the utility model: the utility model oil pumping rod-type overflow controller, can control excessive, the blowout of well head fast, avoid the various security incidents that cause thus.
