敖南油田属于低渗透油藏,水平井的自然产能很低,不经压裂得不到较理想的产量。水平井压裂作为水平井增产措施之一,能压开地层形成裂缝,沟通储层,减缓近井地带油层污染,特别是提高低渗储层水平井产量,使低渗边际油藏得到经济开发。根据压裂施工方案优化结果,成功实现了16口井的现场压裂试验,取得了较好的试验效果,为类似油藏的有效开发提供了良好的技术借鉴和技术支撑。
Aonan oil field belongs to the low permeability reservoir. The natural productivity of the horizontal well is very low, and the ideal yield can not be obtained without fracturing. Horizontal well fracturing, as one of the measures to increase production of horizontal wells, can open fractures and communicate reservoirs to ease oil pollution in near-wellbeds, especially horizontal wells in low-permeability reservoirs and economic development of low-permeability marginal reservoirs . According to the optimization result of fracturing construction scheme, the field fracturing test of 16 wells has been successfully achieved and good experimental results have been achieved, which provides a good technical reference and technical support for the effective development of similar reservoirs.
