This engineering technology is a kind of perforation and the new technology that next pump production process finish, the perforation that avoided process of measure of convention filling aperture and cent of exercise issueing pump are finished 2 times, broken solution cause construction cycle from this long, easy blowout, restore time expenses of long, operation is advanced and a lot of difficult problem.
This craft application is shot post giving a canal need not have after collecting couplet to make perforation of pump new technology work, collect couplet to make pump from the ejaculation that can have realized the function such as perforation of pump fixed position, caber, formation test, perforation couplet makes tool of form a complete set, process, be over well casing column designed 4 respects to undertake study, with next pump perforation the working procedure that pump oil closes 2 for one, post giving a canal need not have after perforation works, can undertake wildcat put into production can have wildcat go into operation, have simplify construction working procedure, reduce exercise cost, avoid to wash kill the well to wait for an advantage to 2 pollution of layer.
