中文摘要：摘要：大牛地气田致密低渗地层特征，本文在总结目前水平井压裂工艺应用情况及其优缺点的基础上，开展段内多裂缝压裂新工艺的研究，特别是段内多裂缝压裂使用高强度水溶性暂堵剂的控制工艺原理以及段内裂缝的干扰分析。现场开展的试验性应用在DPT-8和DPH-60水平井得到了明显的改造效果，为大牛地气田致密低渗储层的改造探索出一条新途径，为以后的压裂改造提供借鉴和依据。
英文摘要：Abstract：Combining tight low-permeability formation feature of Daniudi Gas Field, based on the current application of horizontal well fracturing techniques and the advantages and disadvantages of each techniques, this paper carries out study on new technique of segment multi-fracture fracturing, especially on the principle of control technology by using high strength water soluble temporary plugging agent and the interference analysis of segment multi-fractures. Field test application in DPT-8 and DPH-60 horizontal wells obtained an obvious stimulation effect which provides a new approach of stimulation in tight low-permeability formation and offers reference and guidance for fracturing in future.
