Research and Trial Manufacture of New Type of Swelling Pipe Plugging Tool

Abstract:

In order to improve the plugging success rate when drilling to faults, large cracks, caves which lead mud loss, a new type of swelling pipe plugging tool was developed. The tool can be sent directly to the leakage layer and the plugging material solidifies in the confined spaces, the formed plug with required volume and intensity through the channel in the well trajectory will solve the no-return loss problems. The paper introduces this plugging tool about its structure composition, material selection, manufacture technology and the using methods.
