Optimized Design and Research on Technology Parameters of Concentric Dual-Tube Steam Injection Horizontal Well

Abstract:

The screen pipe completion is the predominated method for heavy oil horizontal well in Liaohe Oilfield, accounting for 83.4% of the total completions. General steam injection has been used for the horizontal wells, resulting in a better exploitation percentage in heel part but a poorer exploitation percentage beyond 1/3 of the distance from the tiptoe to heel in horizontal well. As the concentric dual-tube steam injection technique for horizontal well has just been developed in Liaohe Oilfield, the related supporting technique is not enough. In this paper, researchers consider achieving horizontal wells concentric dual-tube steam injection optimized design as main goal so that the physical model will be established, and also the calculation methods for pressure, the calculation models for quality, heat loss and tapered string parameters along the wellbore will be provided during the concentric dual-tube steam injection for horizontal wells.
