冲洗液或者冲洗型隔离液的除油效率测定方法和装置
摘要：
本发明提供一种冲洗液或者冲洗型隔离液的除油效率测定方法和装置，其中，该方法包括：制备两份被油基钻井液污染的污染石英砂；采用预先配制的冲洗液或者冲洗型隔离液，对第一份污染石英砂进行冲洗处理，得到冲洗后的石英砂；分别对冲洗后的石英砂、第二份污染石英砂，进行油含量测定，得到冲洗后的石英砂的第一油含量、第二份污染石英砂的第二油含量；根据第一油含量、第二油含量，确定除油效率。从而提供了一种可以测定出冲洗液或者冲洗型隔离液的除油效率的方法，进而可以对各类型的冲洗液或者冲洗型隔离液进行除油效率的测定，便于针对油基钻井液的固井去选择出高除油效率的冲洗液或者冲洗型隔离液。
摘要（英）：

The invention provides a method and a device for detecting the oil removal efficiency of a flushing liquid or a flushing type isolation liquid. The method comprises the following steps: preparing twoparts of contaminated quartz sands contaminated with an oil-based drilling fluid; flushing the first part of contaminated quartz sands with the pre-prepared flushing liquid or flushing type isolationliquid to obtain flushed quartz sands; respectively detecting the oil content of the flushed quartz sands and the second part of contaminated quartz sands to obtain the first oil content of the flushed quartz sands and the second oil content of the second part of contaminated quartz sands; and determining the oil removal efficiency according to the first oil content and the second oil content. Themethod for detecting the oil removal efficiency of the flushing liquid or the flushing type isolation liquid is provided to detect the oil removal efficiency of various flushing liquids or flushing type isolation liquid in order to easily select the flushing liquid or the flushing type isolation liquid, with a high oil removal efficiency, for the well cementation of the oil-based drilling fluid.
