【摘要】：体积压裂水平井五区复合模型实用性强、计算速度快,但模型基于定产假设推导,只能计算定产量生产问题,而非常规油藏生产过程中很难保证定产量生产,生产制度往往较复杂。为此,基于叠加原理,将五区复合模型改进为可以计算包括变产量、变流压等任意复杂生产制度的情形,突破了以往五区复合模型定产条件的限制。在此基础上,建立了任意复杂生产制度体积压裂水平井试井解释方法,并对一口体积压裂实例井的不稳定试井资料进行了解释,得到了储层及压裂裂缝参数,说明该方法可以解释具有复杂生产制度的体积压裂水平井不稳定试井资料。研究结果可为非常规油藏体积压裂水平井不稳定试井资料解释提供一定的理论基础。
[Abstract]:The complex model of volume fracturing horizontal well in five areas is practical and fast, but based on the hypothesis of constant production, the model can only calculate the production problem of constant production, but it is difficult to ensure the constant production in the production process of unconventional reservoir. Therefore, based on the superposition principle, the five-zone composite model can be used to calculate any complex production system, such as variable output, variable flow pressure and so on. On the basis of breaking through the limitation of the former five area compound model, the well test interpretation method of horizontal well fracturing in any complex production system is established. The unstable well test data of a volume fracturing example well are interpreted and the reservoir and fracturing fracture parameters are obtained. The results show that this method can interpret the unstable well testing data of volume fracturing horizontal wells with complex production system, and the results can provide a certain theoretical basis for the interpretation of unstable well test data of volume fracturing horizontal wells in unconventional reservoirs.
