摘要

该软件建立了酸压相应的拟三维动态裂缝扩展、酸岩反应、井筒及缝中温度场等数学模型,可计算其动态裂缝扩展变化、酸蚀缝长及导流能力、增产倍比等参数,并可以根据需要输出各种设计计算参数随注液时间变化的各种相关变化数据及图形。该软件可用于施工设计、模拟计算及参数敏感性分析研究,对酸压中的缝高扩展、酸岩反应机理等方面的理论性研究也有重要指导意义。该软件已获总公司开发局采油工程优秀软件开发奖;石油研究院科技进步二等奖。

Abstract

The pseudo-three-dimensional mathematical models for dynamic fracture propagation,acid-rock reaction,temperature field of wellbore and fracture are established and the relevant software is developed,which can be used to calculate the parameters such as variation on dynamic fracture propagation,acid corrosion fracture length and conductivity,production stimulation multiple etc.,and to output data and curves of the calculated parameters with the variation of fluid injection time.This software is suitable for operation design,simulation computation and sensitivity analysis of parameters.It has a guiding significance for the theoretical study on the fracture propagation and acid-rock reaction mechanism.This software wins the award of production engineering excellent software by Development Bureau of CNPC and the second award of science and technology by RIPED of CNPC.
