测井、录井资料在碳酸盐岩储集层评价中的综合应用

The comprehensive application of wireline logging & mud logging data in the carbonate reservoir evaluation

针对胜利油气区下古生界碳酸盐岩储集层非均质程度高、储集空间类型和形态复杂的特点,通过对40多口已钻探井测井、录井资料的统计,归纳了碳酸盐岩储集空间的发育特点,分析了针对碳酸盐岩储集层应用测井、录井资料的识别方法和真假裂缝在测井资料上的响应特征,总结出利用测井、录井资料对碳酸盐岩储集层综合评价的程序,从而达到对储集层的储集物性优劣进行判别的目的,为油气水层的综合评价提供依据。

According to the features of high heterogeneous extent and the complex reservoir space type and morphology at the lower Paleozoic carbonate reservoir in Shengli oil-gas area, through analyzing well line logging & mud logging statistical data from more than forty drilled wells, the paper summed up the development features of the carbonate reservoir space, and analyzed the methods of making use of the well line logging and mud logging data to identify the carbonate reservoir, and presented the response characteristics of true-false fractures on the well line logging data. Based on this, it presented the evaluation program of comprehensively utilizing the well line and mud logging data comprehensively to evaluate carbonate reservoir, therefore reaching the purpose to discriminate superiorities and inferiorities of the reservoir physical properties, and providing the basis for the comprehensive evaluation of oil, gas and water layers.
