精细油藏建模中的不同时序测井资料处理技术——以马岭油田南一区直3^2、直5油藏为例

WELL LOGGING DATA PROCESSING TECHNILOGY OF DIFFERENT TIME SEQUENCE IN FINE RESERVOIR MODELING—A Case Study of C3~2 and C5 Reservoir in No.1 South Block of Maling Oilfield

马岭油田南一区直3^2、直5油藏经历了近13年的注水开发，储层物性、微观孔隙结构和非均质性发生动态变化，造成对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，如果拿这些已经失真的测井曲线来进行精细油藏建模中是不准确的。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准确。本文主要介绍通过新老井测井曲线叠合对比法对测井曲线进行校正。

C3~2 and C5 reservoir in No.1 south block of Maling oilfield have experienced 13 years of waterflood development which causes a dynamic variation of the physical properties of reservoirs,microscopic pore structure and heterogeneity, resulting in a relevant variation of well logs which reflect and record the true variation characteristics.If these distorted well logs were used in fine reservoir modeling,the result would not be correct.Therefore,if we want to obtain a geological model reflecting the initial reservoir geology,we must correct the logs of defferent time sequence to the most primitive state.The geological model built in this way will be more accurate.This paper presents the superposition correction of well logs from new and old wells.
