Abstract: Based on a comprehensive consideration of the effect of temperature field in the fracture on viscostity, leak-off, flow of fracturing fluid and fracture geometry etc, a complete set of numerical models and methods is estabished to calculate hydraulic fracture geometry, including the temperaaure field, flow rate field and pressure field for separate cases of is separately Newtoian and non-Newtonian fracturing fluid as well as settling and suspending proppant measured curves from thxee wells and calculation data are given. Calulation results of this paper, and the results recommeaded by BJ Go. and Halliburton Co, are compared without allowance for temperature changes in the fracture, the numerial methods presented in this paper can be used in hydraulic fracture design calculation and have the advantages of simulating fracturing fluid lass,temperature and pressure changes in the fracture with regults closes to reatity.

摘要： 本文综合考虑缝中温度场与压裂液的粘度、泌失性和流体的流动以及裂缝大小等的相互影响,针对使用牛顿型和非牛顿型压裂液、悬浮式和沉降式支撑剂压裂,建立了包括温度场、流速场和压力场的一整套预测裂缝几何尺寸的数值模型和方法,给出了三口井的实俩对比计算数据和曲线,比较了未考虑温度变化时本文与美国BJ公司和哈里伯顿公司的计算结果。分析表明,本文提供的数值计算方法可用于现场设计计算,并且具有较为实际的模拟压裂液滤失和温度变化,以及缝中压力变化的优越性。
