发明名称 METHOD AND EQUIPMENT FOR HYDRODYNAMIC INVESTIGATIONS OF FORMATIONS ON PIPES
摘要 FIELD: oil and gas industry.SUBSTANCE: method of hydrodynamic investigations involves lowering of equipment for investigation of formation with self-contained measuring device by assembly pipes. Interval of investigation is sealed by packer. Arrangement of fluid influx sequence is provided by feed valve, investigated parameters are recorded by self-contained measuring device at the same time. Packers are released, equipment is lifted to wellhead by assembly pipes with further decoding of self-contained measuring device records. Tubing string is preliminary equipped with a seat, in which detachable receive/transmit module is lowered by geophysical cable. Parameters measured by self-contained measuring device are recorded by electromagnetic communication channel in predetermined time mode. Equipment corresponding to the method is also proposed.EFFECT: improving efficiency of works on formation investigation by formation tester on pipes, improving informativity and speed of decoding or recorded parameters.2 cl, 1 dwg
