Abstract

FIELD: oil and gas industry. SUBSTANCE: this relates to measuring parameters directly in process of drilling gas and oil holes with practically required accuracy. Device has sensors installed in measuring pipeline connected with trough, and among them: temperature sensor, gamma-ray density sensor, electromagnetic flow-rate meter, and additional neutron-type level sensor installed on trough upflow of measuring pipeline. Outputs of all sensors are connected with inputs of switching unit with its output connected with input of microcomputer. Located between source and detector of neutron-type level sensor is layer of material absorbing slow neutrons. EFFECT: high efficiency. 2 cl, 3 dwg
