Abstract
The utility model provides a wellhead anti-contamination device, which belongs to the technical field of down-hole operation in the oil exploitation field. The device is characterized in that the upper ends of telescopic cylinders are connected with a supporting plate, a middle hole is formed in the supporting plate, the two sides of the supporting plate are connected with a handle respectively, the lower ends of the telescopic cylinders are connected with a base, steps are arranged on the base, and the base is provided with a liquid returning port. The device has the advantages that when the telescopic cylinders are lifted, the telescopic cylinders and the base form a sealing space, and a fluid sprayed from an oil pipe is limited in the space to be guided into a casing annulus, so that the fluid in a well is effectively prevented from splashing to pollute the environment and influence the construction; when the telescopic cylinders are put down, the upper planes of the telescopic cylinders and the steps on the base are located on the same plane, so that the normal construction is not influenced.
Description
Technical field
The utility model relates to a kind of well head environmental control system, belongs to underground work technical field in oil exploitation neck city.
Background technology
In oilfield downhole operation process, borehole fluid is often sprayed to well head, causes surrounding environment to pollute, affect construction.Conventionally, unit in charge of construction adopt to reflux bucket by oil pipe fluid conduction to sleeve pipe.But can not, all by fluid recovery, still there is the situation of polluting surrounding environment in the bucket that refluxes.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of well head environmental control system.
An environmental control system, the upper end of retracting cylinder connects gripper shoe, and gripper shoe has mesopore, and the both sides of gripper shoe connect respectively handle, and the lower end of retracting cylinder connects base, has step on base, and base returns liquid mouth.
After adopting said structure, retracting cylinder, in contraction state, does not affect the normal rountrip of tubing string at ordinary times.While having fluid in the oil pipe tripping out, with hydraulic tongs, tubing thread is dismantled, then mention handle, retracting cylinder is opened rising, and oil pipe end is enclosed within tubular space, at this moment, on carry oil pipe, inner fluid, because retracting cylinder encases, around can not spraying, but flows back in sleeve pipe by the Fan Yekou hole on base.
The utility model has the advantages that when retracting cylinder is lifted, form a seal cavity with base, the fluid spraying from oil pipe, by this spatial constraints, is directed in casing annulus, effectively prevents borehole fluid splash, contaminated environment, impact construction.When retracting cylinder is put down, on it, plane and base step, at same plane, do not affect normal construction.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structure top view of the present utility model.
Fig. 2 is structure side sectional view of the present utility model.
Fig. 3 is the opening work schematic diagram of a specific embodiment of the present utility model.
Fig. 4 is the closed condition work schematic diagram of a specific embodiment of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of well head environmental control system, the upper end of retracting cylinder 1 connects gripper shoe 4, gripper shoe 4 has mesopore, and the both sides of gripper shoe 4 connect respectively handle 3, and the lower end of retracting cylinder 1 connects base 2, on base 2, have step, base 2 returns liquid mouth.
Retracting cylinder 1 is made by flexible material, can suitably stretch.
By screws of wellhead, base 2 is arranged on to plane on well head big four flange, can drain line elevator 6 on step, the opening in the middle of step passes through for tubing string; Retracting cylinder 1 bottom and base 2 are tightly connected, and can prevent that fluid from flowing out well head.
In playing lower tubular column process, upper handle 3, can lift retracting cylinder 1, and oil pipe 5 and pipe elevator 6 are all enclosed within the space of retracting cylinder 1 and base 2 formation, has played the effect that prevents that fluid from spraying.
As shown in Figure 3, when handle 3 is put down, retracting cylinder 1 retraction, because the step on retracting cylinder 1 and base 2 is in same plane, does not affect normal construction.
Adopt after said structure,
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
