THE APPLICATION OF GEOSTRESS LAYERING TECHNOLOGY IN FRACTURE DESIGN OPTIMIZATION

  • 摘要: 纵向连续地应力分布对井中储层的压裂施工设计具有重要的指导意义。以卫星油田葡萄花油藏储层为研究对象,结合实际储层压裂数据,优化建立由连续测井数据计算地层最小主应力的数学模型,给出合理的沿井轴连续的地应力剖面。以自然电位曲线的分层为基准,按照一定规则将应力剖面曲线、自然伽马曲线分层取值,并计算待压裂层与上(下)隔层间的"隔层厚度"、"储隔层应力差"、"隔层品质"等参数。利用研究区实际压裂设计数据,以避免压裂过程中待压裂岩层发生"窜槽"为目的,研究给出了不同参数岩层,在压裂排量、压砂强度、单位厚度用液量及压裂方式等施工参数方面的约束条件。实际井例的应用说明,这些条件可有效保障勘探开发压裂工艺的成功率。
