Near-point reverse pull technology of horizontal intersected wells in Wuyang Salt Mine
Due to issues such as low production efficiency,high costs,high safety risks,uncertain brine solubility,and significant environmental impact associated with single-well salt mining,the technology for drilling horizontal intersected wells has continuously developed and improved in recent years.The JSV005-JSV006 wells in the Wuyang salt mine are a set of horizontally intersected wells deployed in the Wuyang depression.This paper systematically summarizes the connection and communication of these wells from various aspects,including wellbore structure,drilling assembly,drilling parameters,drilling fluid performance,directional well trajectory control and geological steering technology,and measures to prevent downhole failures.The focus is on addressing the issue of insufficient horizontal displacement using near-point pullback technology,providing technical support for future salt mining operations.
