| Summary: | With the continuous shortening of horizontal well clusters and the increase in the single-stage fracturing scale, the inter-well interference phenomenon has increased. Moderate inter-well interference can improve single-well production, but excessive inter-well interference will reduce gas well production and slow production recovery. This paper analyzes the causes of inter-well interference from well patterns and spacing, single-stage fracturing scale and engineering. Taking three infill horizontal wells in the Sulige East II area gas field as examples, the effects of inter-well interference on productivity are analyzed by field data, which has certain guiding significance for optimizing fracturing design.
