The present application discloses an integrated device for perforation, storage and protection, including a rupture disk body; an upper joint, the left end of which is connected to the rupture disk body; The right end is a smooth conical surface; the main body of the T-shaped disc is connected with the right end of the Vell; Vell seat, the left end face of the Vell seat is a smooth surface, which is formed in cooperation with the conical surface of the right end of the Vell Metal seal; Vail plug, connected with the right end of the Vail seat, so that the right end of Vail seat forms a sealing structure; lower joint, the left end of the lower joint is connected with the right end of the Vail seat, the lower joint The right end is connected to the perforating gun. In normal production operations, measures such as well killing, well flushing, descaling, wax removal, and pump inspection can be carried out normally without allowing wellbore liquid to enter the formation to cause pollution and affect oil well production.
Description
technical field [0001] The present application relates to the field of oil drilling, in particular, to a perforation storage and protection integrated device. Background technique [0002] Oil resources are a kind of non-renewable resources, so in the process of oil resource exploitation, it is also necessary to do a good job of protecting the oil layers of oil reservoirs, so as to achieve the purpose of sustainable development of oil resources. Low-permeability sandstone oilfields occupy a large proportion of my country's oil resources, and have very rich oil reserves. However, because they are mainly distributed in depression areas and steep slope areas, the structural layers of oil reserves are very complicated. Therefore, It highlights the characteristics of poor reservoir physical properties and small pore throats. [0003] Low-permeability sandstones are mostly located in the middle and deep layers, and the reservoir rocks have poor physical properties, small porosity ...
