保护油气层的室内评价工作主要是借助于有关仪器,测定入井流体对油气层损害后的渗透率变化情况。本文利用JHDS高温高压动失水仪,在确定的实验参数条件下规定了评价各种入井流体对油气层损害程度的模拟评价程序。根据这种程序对江汉油田江陵凹陷沙27井和塔里木塔中TZ-44井岩心进行了模拟评价,通过计算机软件进行数据处理,得出了评价结果,这种评价结果对于现场完井作业具有一定的指导意义。
Indoor evaluation of the protection of oil and gas reservoirs mainly by means of the relevant instruments to determine the permeability of the fluid after damage to the reservoir permeability changes. In this paper, JHDS high temperature and high pressure loss of water analyzer, under the conditions of the experimental parameters provided for the evaluation of a variety of wells into the well fluid damage evaluation of the extent of the reservoir simulation program. According to this procedure, the core of Well TZ-44 in Sha 27 well in Jiangling Sag of Jianghan Oilfield and Tarim Tower was simulated and evaluated by computer software, and the evaluation results were obtained. The results of this evaluation have certain value for on-site completion work The guiding significance.
