特高含水期油田动态监测系统优化技术研究

对大庆油田目前所有的注入剖面和产出剖面测井技术进行了优化研究。在油藏数值模拟的基础上，得到试验区块的模拟吸水剖面和产出剖面，与测井得到的吸水剖面和产出剖面进行了对比分析。为了使两者之间有可比性，对小层流量进行了合理的劈分或合并，求出两者之间的样本偏差。其结果可以用于制定下一步动态监测方案，从而达到对试验区块的动态监测系统的优化，为充分挖掘试验区块剩余油及提高采收率提供依据。

Optimization technique for dynamic monitor system of oilfield in very high water-cut stage

The La-Sa-Xing Oil Field in Daqing Oilfield has already entered very high water-cut developing stage.In order to determine the productivity condition of the oilfield,all the log techniques for injection profiles and production profiles in Daqing Oilfield were optimized.The injection profiles and production profiles of test section gained by reservoir numerical simulation were compared with those obtained by logging.For making comparability of the simulation and log results,the injection(production) quantity in the layer was split or combined.The sample deviations between simulation and logging results can be obtained and used to make the dynamic monitor project of oilfield.The dynamic monitor system can be optimized.
