摘　　要：多种诊断方法的整合应用,可准确掌握地层应力特性、滤失特性等关键参数,指导、优化压裂施工。以渤海湾某探井为例,主压裂开始前,针对该地区高压低渗的储层特征,开展了阶梯升、降排量测试,分析施工压力,预测近井筒摩阻;根据小型压裂测试结果,优化前置液比例,小排量阶段加砂,严格控制施工压力,保障了压裂施工的顺利完成。The integration of a variety of diagnostic methods,can accurately obtain the formation stress characteristic,filtration characteristic and other key parameters,guide and optimize fracturing operation. The paper takes a test well in Bohai bay as an example,before the main fracture and in the light of its reservoir characteristics of high pressure and low permeability,ladder ascending and descending displacement test to the region has been carried out,the operation pressure is analyzed,and near wellbore friction is predicted. According to the test result of small fracturing,the optimized preflush rate,small amount stage sand,and strictly controlling the operation pressure guarantee the successful completion of the fracturing operation.
