摘要
优化选井选层是压裂增产的关键环节 ,而判断油井是否按预测的增油能力进行增产 ,优化压裂设计、压裂配方和现场施工质量以及油藏本身能量大小是压裂的另一方面的关键所在。应用测试资料除了有针对性地进行压裂选井选层之外 ,还可以进行压裂后效果分析及油藏评价。本文通过部分探井试油增产措施增产效果研究的实例 ,特别是对高压、极高压低渗透层压裂效果分析 ,正确运用地层测试卡片对油藏作出了全面评价 ,同时对改造措施的全过程进行了动态评价 ,使试油工作开展得更顺利、效率更高。
Optimizing selecting wells or beds is a key link for increasing production by fracture.There are other important sectors in fracture process which are increasing production whether according to the well's forecast increased power or not,optimizing fracture design,formulation,field operation and reservoir's production power.Testing data's applications can not only help selecting wells or formations to fracture,but also conduct a postfrac effect analysis and reservoir's evaluation.From some studying of stimulation and effect in parts of exploration wells,specially of the fracture effect's analysis in some of high pressure,superhigh pressure and low permeability beds,this paper uses well testing cards to fully evaluate the reservoir perfectly and makes a dynamic interpretation during whole stimulation process that let the testing work going on smoothly and being higher efficiency.
