摘要
压裂是油气藏增产改造的重要措施,压裂水平的高低与施工井层的选择密切相关。应用现代数学手段,建立了一种气井压裂选井选层的新方法,即充分考虑影响压裂效果的各种因素,建立同一区块的电性因素、岩性因素和工程因素与压裂效果的关系模型,进而预测压裂候选井的压裂效果,为优选压裂井层做出定量判断。在大牛地气田的应用结果表明,方法计算简单方便、准确程度高,具有一定的现场应用价值。
Hydraulic fracturing is an important stimulation technique. Fracturing effect is closely related to the selection of target layers. A new method is proposed in this paper using modern mathematics. A new model taking into account relationship between electric property, lithology, engineering factors and fracturing effects is established in this paper. Thus, fracturing results can be predicted and quantitative determination of optimum target wells can also be obtained. It is a simple and accurate method, which contributes a lot to the selection of target wells and layers in Daniudi gas field.
