Technology of Staged Fracturing with Multi-Stage Sleeves for Horizontal Wells in the Ordos Basin

  • 摘要: 鄂尔多斯盆地大牛地气田和红河油田长水平段裸眼水平井分段压裂时,存在长水平段一次性分隔、裂缝发育与井径扩大井段的有效封隔等问题,针对其地质条件、裂缝发育情况及井眼轨迹与井径变化情况,研制了裸眼水平井多级滑套分段压裂工具,形成了裸眼水平井多级滑套分段压裂技术。该技术在鄂尔多斯盆地20余口水平井进行了应用,共完成了200段的压裂施工。应用结果表明:包含裸眼水平井多级滑套分段压裂工具的完井管柱下入顺利,封隔器封隔有效,滑套打开成功率100%,压裂后增产效果良好。这表明裸眼水平井多级滑套分段压裂技术可以解决大牛地气田和红河油田长水平段裸眼水平井分段压裂中存在的问题,可在鄂尔多斯盆地进行大规模推广应用。
    Abstract: During open-hole staged fracturing operation in horizontal wells of Daniudi Gas Field and Honghe Oilfield in the Erdos Basin, there were challenges such as the separation of long horizontal sections in one trip, the development of natural fractures and ineffective isolation due to hole enlargement.Considering the geological conditions, well trajectory and hole diameter changes in both fields, the staged fracturing tools with multi-stage sleeves for open hole in horizontal wells were developed and relevant operation techniques were established.The tools were applied in more than 20 wells in the Erdos Basin with totally 200 stages fractured.Field applications achieved good results, including the smooth running of the completion string of the staged fracturing tools with multi-stage sleeve for open hole in horizontal wells, effective sealing of packer, sleeve opening with high success rate, and dramatic increase of production after fracturing.These proved that these tools could solve the problems that occurred in open hole staged fracturing operations in Daniudi Gas Field and Honghe Oilfield, and are appropriate for intensive application in the Erdos Basin.
