固井注水泥过程的动态描述研究

Description on Dynamic Cementing Process

注水泥施工参数的合理与否直接关系到固井质量的好坏,应用一定的计算模式描述注水泥动态施工参数并进行模拟,具有重要的现实意义。通过对注水泥动态过程的综合分析研究,从注水泥基本理论出发,建立了描述这一过程中任一时刻各动态参数的计算模式,并在此基础上开发了注水泥过程动态模拟软件。经过江汉油田几口井的实例验证,模拟结果与实测结果相符程度较高,满足了工程要求。

If cementing the construction parameters are reasonable,it is directly related to the quality of cementing quality.Application of certain mode of calculation described in cementing construction parameters of dynamic simulation has significant practical significance.Through comprehensive analysis and studies on the dynamic process of cementing,it establishes the dynamic parameters of the model which is a description of this process at any one time,and on this basis,developed the cementing of dynamic simulation software.Through a few examples of calculation for wells in Jianghan Oilfield,the simulation results and the measured results are in higher match,meeting the engineering requirements.
