PUMPING UNIT BYPASS SYSTEM Russian patent published in 2022 - IPC E21B47/00 E21B17/02 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry and can be used both for the extraction of liquid or gaseous hydrocarbons, and for work in wells with a horizontal termination without extracting pumping equipment. The bypass system of the pumping unit contains a y-adapter with an electric centrifugal pump installation (ECPI) and a bypass line attached to it. The bypass line consists of a column of bypass pipes, a bypass line holder and protectolizers connecting the bypass line and the ECPI into a common structure along the entire layout. A guide for the delivery vehicle, made in the form of a coupling or non-coupling pipe column, with a length determined by calculation based on the condition of the delivery vehicle reaching the required area of the horizontal section of the well, is rigidly connected to the bypass line holder from below. The diameter of the specified guide is no more than double the diameter and no less than one diameter of the delivery vehicle and/or the delivered equipment.

EFFECT: increase in the passage depth of the delivery vehicle, minimizing the risks of equipment not reaching the required areas in the well, eliminating the risks arising from the movement of the delivery vehicle and the equipment of the production column above the shank.
