研究了高温底水物理模拟实验系统的组成,建立了稠油热采底水条件下物理模拟实验方法,并以渤海LD底水油田为例,利用该系统开展高温底水物理模拟试验研究,模拟研究了热采驱替方式、底水能量、井型对底水侵入的影响。高温底水物理模拟实验技术的开发,能同时实现高温和底水条件下的物理模拟实验,该技术可推广应用于海上底水稠油油藏热采技术的实验研究中,为海上底水稠油油藏高效开发方案的编制提供技术支持。

This paper studied the composition of a physical simulation experiment system for high temperature bottom water and established a physical model experiment method for the thermal recovery of heavy oil with bottom water. Taking LD reservoir with bottom water in Bohai Sea as an example,this system was used in the study of high tem-perature bottom water physical simulation experiments to analyze the influence of thermal displacement method, bottom water energy and well type on the bottom water intrusion. The technology is able to realize physical modeling experiments under the conditions of high temperature and bottom water. It can be applied in the experimental study on thermal recovery processes of heavy oil reservoir with bottom water and provide technical support for the efficient exploration plan.
