精细油藏模拟中不同开发阶段测井处理方法研究

Research on well logging data processing technology of different time sequences in fine reservoir modeling

马岭油田南一区直3^2、直5油藏经过多年的注水开发，储层物性和微观孔隙结构已发生动态变化，反映和记录地下储层真实性变化特征的测井曲线发生相应的变化。这些已经失真的测井曲线来进行精细油藏模拟中是不准确的。因此，要得到反应油藏原始地质状况的地质模型，必须把不同时序的测井曲线校正到油藏最原始状态，由此建立的地质模型才更加符合地质规律。本文主要利用新老井测井曲线叠合对比法对测井曲线进行校正。

The C32 reservoir and C5 reservoir in Nanyi block of Maling oilfield have experienced many years of waterflood development which causes a dynamic variation of the reservoir physical property and microscopic pore structure, resulting in a relevant variation of well log that reflects and records the true reservoir conversion characteristics. If these distorted logs are used for fine reservoir modeling it＇s inaccurate. So, if we want to obtain a geologic model that reflects initial reservoir geology,we must correct the logs of different time sequences to the most primitive reservoir state. The geologic model built in this way will be more accurately. This paper mainly introduces superimposing correlation techniques of logs from new and old well.
