东胜气田作为华北石油第二大主力区块,在探索致密油气方面进行了多年的研究尝试,通过加大对储层的地质构造、物性研究、压裂工艺的选择、压裂设计的优化等,不断提升了压裂改造效果,取得了重大突破。本论文现结合压裂现场实际情况,针对东胜气田压裂改造难点,从压裂工艺的选择、控水控缝高工艺研究、施工参数优化、压力异常情况等方面入手进行分析,并提出了解决方案,为指导现场压裂施工提供了依据。
Dongsheng Gasfield, as the second main force of North China Petroleum, has been trying its best to explore tight oil and gas for many years. By increasing its geological structure, physical properties, selection of fracturing technology and optimization of fracturing design, , And continuously improved the effect of fracturing and made major breakthroughs. Based on the actual situation of fracturing site, this paper analyzes the difficulties of fracturing in Dongsheng gas field, and analyzes the selection of fracturing technology, research on control technology of water control seam height, optimization of construction parameters and abnormal pressure. Solution to provide the basis for the guidance of on-site fracturing.
