BRIDGE CONNECTOR FOR CONNECTING A CHAIN HYDRAULIC FRACTURING RESERVOIR TO THE WELLHEAD AND METHOD FOR INSTALLATION THEREOF Russian patent published in 2023 - IPC E21B33/68 E21B43/26 

FIELD: drilling.

SUBSTANCE: group of inventions relates to equipment for drilling petroleum and gas boreholes, more specifically, to a connecting bridge for a hydraulic fracturing reservoir. Bridge connector for connecting a chain hydraulic fracturing reservoir to the wellhead comprises a bridge connector head, a first and a second connecting blocks, a first and a second bridge pipe inserts. The bridge connector head includes an axial through channel and a separate inlet. The axial through channel has a first longitudinal axis. The separate inlet has a second longitudinal axis and is in fluid communication with said axial through channel. The first and second connecting blocks are in fluid communication with the axial through channel of the bridge connector head. The first and second bridge pipe inserts are attached to the first and second connecting blocks, respectively, and are in fluid communication therewith. The first and second bridge pipe inserts are configured to attach the bridge connector head to the same wellhead. Method for installing a bridge connector for connecting a chain hydraulic fracturing reservoir to the wellhead includes the stages of providing a chain hydraulic fracturing reservoir, configuring the bridge connector head, configuring the first and second connecting blocks, and attaching the first and second bridge pipe inserts to the first and second connecting blocks, respectively. The hydraulic fracturing reservoir comprises a wellhead pipe insert and an outlet. The wellhead pipe insert is configured to provide an axial fluid flow. The outlet is configured to selectively transmit the hydraulic fracturing fluid flow through the wellhead pipe insert to the bridge connector. The bridge connector head is configured so that the inlet is in fluid communication with the outlet of the chain hydraulic fracturing reservoir. The first and second connecting blocks are configured so as to be in fluid communication with the axial through channel of the bridge connector head. The first and second bridge pipe inserts are configured to attach the bridge connector head to the same wellhead.

EFFECT: shorter downtime during hydraulic fracturing operations and higher safety and productivity.
