Abstract

The invention discloses auxiliary equipment for petroleum excavation. The auxiliary equipment comprises a cylinder, a plurality of annular grooves are formed in the cylinder and partition the cylinderinto a plurality of rigid parts, flexible parts are arranged in the annular grooves, and the heights of the flexible parts are gradually decreased from the upper end of the cylinder to the lower endof the cylinder; and the flexible parts comprise leather layers, closed annular filling cavities are constituted by the leather layers and the annular grooves and each filled with a plurality of firstballs, a plurality of second balls and a plurality of third balls, and the auxiliary equipment further comprises a plurality of protecting mechanisms. The compressive strength of all the positions ofthe cylinder is different, by additionally arranging the flexible parts with the lower cost, the production cost of the cylinder is lowered, the transport and storage steps of the cylinder are also easier, the cylinder has the ability to adapt to various soil environments, and the universality of a protecting sleeve is improved.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to an auxiliary equipment for oil excavation. Background technique [0002] The drill pipe is a steel pipe with a thread at the end, and the thread is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. As one of the important oil extraction equipment, the drill pipe can transport the drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. [0003] Because the drill pipe needs to extend into the ground, the drill pipe must be designed to withstand the enormous pressure from the soil. In order to improve the service life of the drill pipe, reduce the process cost, and avoid the drill pipe from being damaged due to soil extrusion during use, a protective sleeve is usually sleeved on the outer side of the conveying section of the drill p...
