摘要:

由Geertsma.Klerk.Perkins[1][2][3]等提出的几套二维动态裂缝几何尺寸的计算模型,都没有考虑温度的影响,这显然是不合理的。本文考虑到井底温度变化和地层原始温度的影响,首先建立了滤夫速度是温度、时间的函数的缝中液体温度场模型,然后建立了与温度相关的动态裂缝几何尺寸的两套数值计算模型,最后举例说明了上述模型的使用方法。本文提供的计算模型对生产实际有一定的实际意义,为计算机实时模拟动态裂缝的变化提供了有效途径。

Abstract:

It is obviously unreasonable that a few two-dimension models, which are used to predict the geometric shape of dynamic fractures developed by Geertsma, Klerk, Perkins et. al, don t consider the influence of temperature. Taking the influence of initial formation temperature and wellbore temperature into consideration, this paper first sets up a temperature field model in a fracture in which the leakoff rate is the function of temperature and time, then develops two types of models predicting the geometric shape that considers the temperature distribution in the fracture,and finally exemplifies the use of
all above models.
All models presented in this paper are helpful to the fracturing operation practice,and give a way of real time stimulation of the dynamic fracture geometric shape by computors.
