【 摘 要 】
Horizontal well fracturing technology has been applied in tight oil reservoirs, and most horizontal wells show decline after high production period. In order to define the change law of horizontal well production based on the geological and engineering factors on the influence of the horizontal well production change, the paper uses Daqing region A block of the horizontal well production data in view of the analysis of the regressive method. Based on the analysis of each decline method, it is considered that the horizontal well production in this block is the exponential decline, which lays a foundation for the prediction of horizontal well production and the adjustment of the later development system.
