Abstract
The utility model relates to an oil well packer which comprises an upper joint 1, a rubber barrel 3 and a lower joint 4 and is characterized in that the upper and lower ends of the rubber barrel 3 are provided with ring-shaped protection rings 2. The oil well packer is simple in structure and reliable in work, is applied to various underground work in oil fields, and as the protection rings 2 with larger external diameter are adopted, the rubber barrel 3 can be prevented from being damaged due to collision with the well wall in the setting and the removing processes.
Description
Technical field: the utility model relates to a kind of oil field downhole tool, especially for a kind of Wel packing of all kinds of underground work.
Background technology: before the utility model, each oil field is used for the packing element that the used packer of all kinds of underground work adopts rubber system more, because its Material Strength is lower, rising, bumping and damage through regular meeting and the borehole wall in the construction down, makes troubles to construction.
Summary of the invention: the purpose of this utility model is: for oilfield downhole operation provides a kind of Wel packing, because this device has the bigger protection ring of external diameter, thereby playing, can prevent in the construction down that the packing element and the borehole wall from bumping and damage.
The purpose of this utility model realizes by following measure: a kind of Wel packing, comprise top connection, packing element, lower contact, and it is characterized in that circular protection ring all being installed at the packing element upper/lower terminal.
Simple in structure, the reliable operation of the utility model is used for all kinds of underground work in oil field, owing to have a bigger protection ring of external diameter, thereby is playing, can prevent in the construction down that the packing element and the borehole wall from bumping and damage.
Description of drawings: Fig. 1 is the structural representation of Wel packing.
The specific embodiment: Wel packing is to be made of top connection 1, protection ring 2, packing element 3, lower contact 4 etc., and packing element 3 upper/lower terminals all are equipped with circular protection ring 2.
The operating principle and the using method of Wel packing are: earlier by top connection 1, lower contact 4, this device is connected with tubing string, then can carries out underground work; Rising, down in the construction, under the effect of the bigger protection ring 2 of external diameter, thereby can prevent that the packing element 3 and the borehole wall from bumping and damage.
