HIGH-PRESSURE SYSTEM FOR MULTIPLE HYDRAULIC FRACTURING WITH COUNTING SYSTEM

摘要

FIELD: machine building.;SUBSTANCE: invention relates to a high-pressure system for multiple hydraulic fracturing and a system of a manifold mounting hydraulicvalve (MMHV) for connection with a production string to enable isolation of a prospective formation within a well. In particular, this system provides the possibility of access to a ground formation for hydraulic fracturing of a zone-of-interest formation and extracting raw hydrocarbons. System as a whole contains a plug counting system, a capturing system and a valve system, while dropping a group of plugs down the production string allows sequentially capturing individual plugs inside separate MMHV for successive hydraulic fracturing operations.;EFFECT: technical result is to increase the valve efficiency.;14 cl, 20 dwg
