GARIPOV PACKER WITH ELECTRONIC INSTRUMENT (VERSIONS) AND METHOD OF ITS IMPLEMENTATION Russian patent published in 2013 - IPC E21B33/128 E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: packer with electronic instrument includes mandrel with sealing elements, dividing elements between them, movable and fixed elements. The packer is equipped with electronic instrument with a sensor to control leakproof state of sealing elements in process of well operation. According to the first version electronic instrument with a sensor or sensor of electronic instrument is located in leakproof space at permanent pressure between sealing elements. According to the second version electronic instrument with sensor or sensor of electronic instrument is located outside sealing elements or in sealing and dividing elements. The sensor of electronic instrument is connected hydraulically with leakproof space at permanent pressure between sealing elements. Method of packer with electronic instrument operation includes running-in of tubes with the above packer, measurement of parameters and their transfer to the surface. Electronic instrument with sensor or sensor of electronic instrument is installed with possibility of fluid communication with space between sealing elements in order to control leakproof state of sealing elements; at that packing of the packer is made and leakproof space is formed at permanent pressure between sealing elements as in hydraulic chamber. When packer with electronic instrument with sensor is set parameters are measured in the above space.

EFFECT: increased efficiency of well operation.
