苏北盆地页岩油体积压裂技术研究与应用

Research and application of shale oil stimulated reservoir volume technology in Subei basin

随着勘探开发技术的不断发展,页岩油不断取得重大突破,以压裂为主要改造措施的开发技术成为页岩油领域研究的热点。苏北盆地泥页岩发育良好,开发潜力巨大,通过对苏北盆地页岩油储层特征分析,按照“主攻甜点,肥瘦兼顾”的整体思路,采用分段体积压裂工艺改造,施工顺利,通过裂缝监测显示,达到了体积压裂造复杂缝的目的,形成了苏北盆地页岩油体积压裂工艺技术,达到预期的增产效果。

With the continuous development of exploration and development technology,shale oil has continuously made major breakthroughs.Development technology with fracturing as the main improvement measure has become a hot spot in the field of shale oil research.The shale in the Subei basin is well-developed with huge potential.Through the analysis of the characteristics of the shale oil reservoir in the Subei basin,in accordance with the overall idea of"focusing on sweet spots,taking care of all spots",the segmented stimulated reservoir volume(SRV)technology is used for the field and the construction is successful.According to the monitoring of fractures,the purpose of creating complex fractures by SRV has been achieved,the SRV technology of shale oil in the Subei basin has been formed,and the expected production increase effect has been achieved.
