Description

Oil leakage dredging device

Technical Field

The utility model relates to an oil field is equipment technical field for the well, especially relates to a ware is dredged in oil leak.

Background

At present, a packing sealing device used in an oil exploitation field mainly comprises a packing box, a packing, a polish rod and a gland 4. The packing box is a circular steel cylinder, the center of the packing box is axially provided with a through hole for the oil pumping polished rod to pass through, and the polished rod passes through the through hole; the lower end of the steel cylinder is connected to the wellhead through a connecting joint, a cavity for placing a packing is arranged in the steel cylinder, and the packing is sleeved on the outer wall of the polished rod and embedded in the cavity; the steel cylinder top is provided with the gland with the cavity adaptation, and the gland passes through gland bolt axial and compresses tightly the packing, makes the packing take place axial deformation, produces radial expansion's trend simultaneously, and then makes the packing hug closely packing box inner wall and polished rod outer wall, fills up the space, prevents the oil spout oil leak.

In the oil extraction process of the oil pumping unit, the polish rod continuously reciprocates up and down in the through hole, and as friction between the polish rod and the packing is severe, on one hand, the packing is high in loss, and the sealing performance is increasingly poor; on the other hand, the friction can cause the temperature of the polish rod to rise, and the viscosity of crude oil at the wellhead is reduced, so that the crude oil is easier to overflow; in addition, the high water-containing well with high water content of the effluent of the oil layer or serious pollution of formation water causes corrosion of the polish rod, failure of the sealing ring and the like, which can cause oil leakage at the joint of each interface between the wellhead packing box and the polish rod and even blowout, thus leading to waste of crude oil, environmental pollution and serious influence on normal production.

In recent years, technical personnel of various large oil field enterprises also invest a large amount of manpower, material resources and financial resources to improve the material quality and equipment technology of wellhead packing, packing boxes, polished rods and sealing rings, even the original single packing is improved into double packing at present, the oil leakage problem of the wellhead is relieved to a certain extent, the investment is much larger than that of the original single packing, the replacement period of the packing, the polished rods and the sealing rings is temporarily prolonged, and the problem of environmental pollution caused by oil leakage is not fundamentally solved. When the oil leakage is not found in time without being attended or at the well head, the oil leakage on the well head pollutes a large area of soil around the well head field, so that the irrecoverable environmental pollution is caused.

In view of the above problems, it is desired to develop a device capable of effectively solving the environmental pollution caused by oil leakage.

Disclosure of Invention
