METHOD AND DEVICE FOR CONTROL OF PROCESS OF SIMULTANEOUS SEPARATE OPERATION OF MULTIPLE-ZONE CASED WELLS (VERSIONS) AND EXECUTION MODULE IN DEVICE (VERSIONS) Russian patent published in 2013 - IPC E21B47/12 E21B43/14 

FIELD: oil and gas industry.

SUBSTANCE: method involves lowering of packers and equipment for extraction (pumping) of product in interval of product extraction on tubing string located against each productive formation. Down-hole measurements are performed by sensors. Obtained date is transmitted to ground receiving-processing unit by means of electronic self-powered measurement modules transmitting data signals by tubing string by electromagnetic pulses to common electronic self-powered transmitting module. Module is installed in tubing string assembly above the highest productive formation. Data high-frequency signals are amplified and transmitted to ground receiving-processing unit through rock. Equipment for extraction (pumping) of product is controlled by communication channel or by hydraulic communication channel using independent electronic modules. Modules contain housing in which the following is installed: valve for control of supply (removal) of fluid medium controlled by step-type tiny engine with driving mechanism of valve gate rotation, autonomous power supply unit, receiver of fluid pulses and dipole receiver of electromagnetic oscillations, amplifier modules of decoding device and power amplifier.

EFFECT: improving efficiency of monitoring of simultaneous separate operation of wells by means of provision of reliability of data transmission by two-way wireless communication between well equipment and ground receiving-processing unit.
