Збільшення надійності і безпеки експлуатації високодебітних свердловин

Abstract

The article contains information about the problems of protecting high-yield wells. The principles of operation of the ball valve of the shut-off valve and its main differences from the flopper shutter are considered in detail. Also, the geometric parameters of the ball itself are demonstrated in detail. Examples of design are given, and the operating principle of the most common models of shut-off valves is described. The authors explain the necessity of equipment for high-bit wells with complexes of underground downhole equipment (CUDE). There are the circumstances in which the potentially high emergency danger of oil and gas producing enterprises is increased, and the measures necessary to improve them.
