缝高控制与薄层压裂

Controlling Gap Height and Fracture to Thin Layer.

薄层压裂的关键问题是如何控制缝高 ,而对缝高的影响因素较多 ,通过软件模拟和国内外文献资料及实验数据 ,证实薄层压裂缝高的主要影响因素为粘度和排量。结合以往薄层压裂的缝高延伸情况 ,确定了小排量、低粘度压裂液原则 ,现场实验 5口井 ,取得了较好的压裂效果。

The key problem of the fracture to thin layer is how to control gap height on which many factors influence.By soft ware analog and domestic and abroad paper's materials and experiment data,it is confirmed that the main influencing factor to gap height of fracturing to thin layer is viscosity and backflow volume.Combing with extend case of gap height of the former fractured thin layer,the principle of small backflow volume and low viscosity is determined,which has gained a good fracture result by field test to 5 wells.
