摘要
在进行储层损害室内评价时 ,选择和明确规定合适的试验条件 ,是正确认识储层损害机理和针对给定的储层优选出合适的、对储层损害较小钻井液的关键 ,亦有利于对不同来源岩样或相同岩样在不同时间及不同试验室所做结果进行对比。目前国内外已制定的标准 ,均没有结合所用试验装置明确规定出合适的试验条件。在对低渗气层岩样进行室内试验研究的基础上 ,提出了气层岩样气相渗透率测定条件和钻井液损害岩样条件 。
So as to find out the formation damage mechanism of oil or gas reservoirs, it is a key to select appropriate experimental conditions and drilling fluid when formation damage evaluating tests are carried out in lab.Present standards set at home and abroad don′t definitely specify suitable experimental conditions.On the basis of indoor research of low-permeability gas sands cores,some experimental conditions of measuring gas phase permeability and drilling fluid damage rock are proposed.
