Goshovs'kyj S. Using the explosion energy in the technologies of well construction

The dissertation deals with the improvement of the technologies using the explosion energy in well drilling and completion the basis of the theoretical research and commercial data. There has been obtained the scientific ground for the further development and solution of the problem of releasing of drilling tools stuck. There has been proposed the solution of the problem of drill pipes cutting, the fragmentazation of junk metal in the downhole and the creation of keyseats be means of well shooting. There has been made the analytical evaluation of the torque moment change in the threaded joints an the moment of its torpedo shooting when unscrewing. There have been carried out the analytical and experimental research of the influence of ballistic characteristics and parameters of the combined obstacles "washing fluid - casing string - cement ring - rock" on the penetrative ability of the dun and jet perforators. Recommendations have been proposed as to the choice of a type of a shooting - explosion devic e and its operation regime. It has been done for the achievement of the maximum effectiveness of the perforation to prevent the fracturing of a casing string and cement stone in the casing string borehole annulus. There have been improved the known technologies and proposed new ones for the increasing of the efficiency of shooting - explosion works in well. They are as follows: locators, selective torpedoes, more powerful torpedoes and devices for locating the explosive action.
