Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fracturing equipment, in particular to a fracturing equipment. Background Art
[0002] Fracturing equipment is a type of equipment used in the extraction of unconventional energy sources such as shale gas, coalbed methane and tight oil. It is mainly used to inject high-pressure liquid into underground rock formations to break up the rocks and increase the release of underground energy. Fracturing equipment includes fracturing pumps, fracturing trucks, fracturing fluid tanks and other related equipment. By applying high pressure, rock cracks are expanded, thereby increasing the fluidity of energy so that it can be extracted. Fracturing equipment plays an important role in the extraction of unconventional energy and promotes the development of the energy industry.
[0003] During fracturing, first insert the casing into the bottom of the wellhead, then inject cement to strengthen the supporting capacity of the well wall. After the cement solidifies, pass the packer into the casing through the tubing. When it reaches the designated position, fix the packer, and then use a perforating gun to perforate at the designated position. Then introduce pressure fluid and sealing balls. The packer enters the packer under the transmission of pressure fluid and forms a seal with the packer. Under the sealing of the packer and the sealing balls, the pressure fluid enters the oil layer through the perforations to create cracks. After multiple stages of fracturing, production can be carried out.
[0004] When using a packer for plugging, the support force of the packer is fixed. When the pressure of the pressure fluid increases, the packer may slip, resulting in fracturing failure and poor stability. Utility Model Content
