密闭取心 meaning in Chinese
sealing core drill
Examples
- Determination of the saturation parameters by application of the sealed core data
应用密闭取心分析资料求取饱和度参数 - Besides , the natural core in - house long - term washing out experiment has proved that waterflood efficiency of pressure coring can reach as high as 80 % ~ 90 %
天然岩心室内长期水冲刷实验证实了密闭取心的水驱油效率可达80 % ~ 90 % 。 - In order to further improve the calculation accuracy of oil saturation , the correlation relation is established by way of pressure coring data and then makes pyrolysis analysis data reach the evaluating standard of pressure coring
为进一步提高含油饱和度的精度，通过密闭取心资料建立含油饱和度的校正关系，使热解分析资料评价达到密闭取心评价水平。 - The paper points out that the reasons for displacement efficiency improving of pressure coring well are as follows : firstly , extra - high injection multiples ; secondly , extra - low critical drive ratio ; thirdly , high velocity fluid ' s big differential pressure drive during the process of coring
得出导致矿场密闭取心井驱油效率高的原囚：一是特高的注水倍数，二是特低的临界驱动比，三是取心过程中高黏度流体的大压差驱动。 - Based on the preferable comparability of lithology between homogeneous core used in lab lest and that in strongly water washing part of inspection wells , forming condition of displacement efficiency in strongly water washing part of pressure coring inspection wells in waterflooded area has been analyzed , and reasons for the difference of displacement efficiency between pressure coring and in - house waterflood test have been discussed
摘要基于室内实验采用的均质岩心与检查井强水洗段岩性物性较好的相似性，通过对水淹区密闭取心检查井强水洗段驱油效率形成、室内水驱油模拟条件的分析，指出了密闭取心与室内水驱油实验驱油效率差别的原因。
