MODELING AND PRACTICAL APPLIKCATION OF A POWER FIELD AT CONIC CHARGE EXPLOSION

Abstract

An analysis over of character of the isodenses of conical charge explosive products, got by mathematical design, is brought. The features of distribution of the power field are certain depending on direction of initiation of the truncated conical charge. The complex character of intermediate initiator using in a downhole charge as the truncated cone at his location in the ground part of hole is discussed. It is established that the shape of the field of isolines of the density of PD is due primarily to the form of the charge, regardless of the place of its initiation; the prevailing field development occurs relative to the Z axis, that is, along the X axis of the conical charge by the action of its narrow part. This is due to the spread of the products of detonation normal to the sloping surface of the cone. If you associate the total area of the PD density field with the total explosive energy, it is possible to redistribute the flow of energy due primarily to the orientation of the bases and sides of the truncated cone charge, and then to its initiation location. Control of the dynamics and direction of development of the force field is possible by choosing the location of application of the initiating pulse, the vertical direction and traditional movement with the coincidence of areas of the array in the horizontal direction. The advantages of using a mixed circuit switching scheme have been proven by industrial testing of the method.
