摘要:
针对因井筒条件或隔层封挡能力达不到机械分层压裂要求的薄互层油藏,提出用暂堵转向分层压裂工艺来实现非均质油层逐层充分改造。建立了暂堵球坐落并有效封堵射孔孔眼的数学模型,分析了暂堵球封堵不同压裂油层厚度所需的最低施工排量条件,评价了Z-1型暂堵球封堵承压和溶解性能,在W-55井实际应用中实现了两个非均质油层的逐层改造。
Abstract:
In order to effectively produce reserves of thin interbedded reservoirs, it was proposed to apply the temporary plugging and diversion separate layer fracturing for realizing the layer-by-layer stimulation of each layer when the mechanical separate conditions can not be met. Under the condition that the temporary plugging ball can effectively occupy the perforating blast hole and achieve the sealing and non-shedding construction, the Z-1 type temporary plugging material was optimized based on experiments to meet the requirements of sealing pressure in fracturing process and rapid dissolution after fracturing process. The successful application of well W-55 in the field has realized the goal of layer-by-layer stimulation of two heterogeneous oil layers.
