Essay

The thesis deals to the investigation of the problems of preventing the destruction of the bottomhole formation zone and the elimination of the sand plug at the bottom of the well. The technology of intensification of work of wells with unstable reservoirs is improved, which includes expansion of the wellbore in the interval of the productive formation during its construction and filling the formed hollow space with a grouting mortar to form a cement stone of high strength and permeability; washing the sand plug at the bottom of the well with an aqueous solution of a foaming surfactant and a foam stabilizer along a string of flexible pipes, the bottom of which is equipped with a device for destroying a sand plug.
