introduced are wet-connector horizontal well logging techniques and problems in application 介绍了湿接头水平测井工艺,以及现场运用中存在的主要问题并提出了解决措施。
we use tcp / ip protocol to ensure the reliability of the process . by the checkpoint-log technique, we can ensure the recovery of the process 我们采用tcpny协议来保证该数据传输过程的可靠性;通过记录检查点的方法,保证了该数据传输过程的可恢复性。
with the consideration of the problems existed in daqing oil field, such as isotopic contamination during isotopic water injection profile logging, high permeability streaks in formation, injection profile testing for polymer injector, et al ., many characteristic production logging techniques have been developed 摘要针对大庆油田现场存在的同位素吸水剖面测井同位素沾污、地层大孔道、注聚井注入剖面测试等问题,本着实用、配套的原则,重点发展了多项特色生产测井技术。
this method, without any new well logging technique, only mines the information quantitatively and does some meaningful work o n the quantitative interpretation of the temperature logs, which makes most of the existing resources and have good applicability and practical value 该方法在不附加任何新测井工艺的情况下,充分地利用了现场实际生产中已有的大量温度计测井资料,进行信息定量挖掘,在温度测井信息的定量解释上做出了有意义的结果,很好地利用了现有资源,具有较好的应用前景和实际应用价值。
among these techniques, log system is the foundation of fault-tolerance in distributed database systems . many sub-systems can benefit from powerful log system, such as distributed query, parallel processing control, transaction recovery, and message-based fault-tolerable log techniques . in addition, log can be used to maintain consistency among database's duplicates 其中,日志是错误容忍与分布式数据库系统的基础,分布式数据库系统可靠性通过一套基于日志的机制得到保证,如用于分布式更新、并发控制、事务恢复、错误容忍的消息日志技术;当网络中断或隔离,日志可用于维护数据副本的一致性。
