钻井液完井液损害油层室内模拟评价程序
Laboratory simulation evaluation program for the damage of drilling fluid and completion fluid to oil formation
【摘要】 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。
【Abstract】 The laboratory evaluation for protection oil-gas formation is conducted mainly with related instruments to monitor the permeability change of the core. JHDS HTHP Dynamic Filtration Press is used to evaluate the damage to oil-gas formation according to specific simulation evaluation program for each kind of fluid under definite test parameters. The program has been used in Sha 27-well in Jianghan Oilfield and TZ-44-well in Tarim and the data are processed by computer. The results have some directive function for on-site completion work.
