摘要
随着化学驱技术在油田矿场的推广应用,现有软件的化学驱模拟功能越来越难以满足油田实际需求.通过调研化学驱数值模拟技术,阐述油藏数值模拟技术的发展现状,并将CMG、ECLIPSE、UTCHEM等8种软件分为综合型软件化学驱模块和单一化学驱软件两类,分析各软件的优缺点,对比各软件的综合性能及化学驱功能,指出化学驱数值模拟软件技术存在的主要问题及发展方向.现有软件在增强前后处理功能的同时,还需进行核心的完善.化学驱软件考虑众多物理化学因素,导致求解困难,需要在数值模拟的稳定性和机理描述的合理性之间进行适当取舍.虽然国产数值模拟软件在整体性能上弱于国外商业化软件,但是在化学驱数学模型和机理描述上具备较大优势.
Along with the popularization and application of chemical flooding technology in oilfields,it is more and more difficult for the existing chemical flooding simulators to meet the actual needs of oilfields.So the further research of chemical simulation technology needs to be carried out immediately.Based on the investigation of chemical simulation technology at home and abroad,the history and present situation of chemical simulation technology are analyzed,CMG and other seven simulators are divided into two categories:comprehensive reservoir simulators and special chemical flooding simulators,anda detailed introduction of them is made.Then the authors summarize the advantages and disadvantages of each simulator,and make a comparison of different simulators in their comprehensive performance and chemical flooding function.After a lot of work,at last the authors point out the main problems of chemical simulation technology,and give some advice about the development direction of chemical simulation technology.
