摘要:
 


为准确评价低渗透、特低渗透储层，基于水平井井身结构、压裂裂缝的形态和间距，结合不稳定渗流力学理论，得出不动管柱多级压裂油气

井不稳定产能评价方法。根据储层、流体、井身结构等参数，建立不动管柱多级压裂水平井产能预测的数学模型，编制软件，计算出不同生产压力下产量随生产时间的变化曲

线，以及不同生产时期下井底流动压力与产量之间的关系曲线。大庆油田现场2口井中的应用，产量变化与实际误差分别为37%和55%。该方法可有效评价储层及压裂改造

效果，实现多级压裂水平油气井产能评价。

Abstract:
 

In order to accurately evaluate the low permeability and ultralow permeability

reservoirs, based on the horizontal well structure, fracture shape and spacing, combined with the theory of unstable seepage mechanics, the

evaluation method of unstable productivity of multistage fracturing oil and gas wells with fixed string is obtained. According to the parameters of

reservoir, fluid and wellbore structure, the mathematical model for productivity prediction of multistage fractured horizontal wells with fixed string

is established, and the software is compiled to calculate the production curve with production time under different production pressure, as well as

the relationship curve between bottom hole flow pressure and production in different production periods. This method has been applied in two wells

in Daqing Oilfield, it shows that the error of production variation and actual production is 37% and 55% respectively. This method can

effectively evaluate the reservoir and fracturing effect and realize the productivity evaluation of multistage fracturing horizontal oil and

gas wells.
