| 中文摘要: |
| 南海东部古潜山火成岩地层为双孔介质，岩性复杂，利用常规测井资料对储层进行定量评价及流体识别非常困难。MREX二维核磁测井仪器主要测量地层孔隙流体中的氢信号，不受岩石骨架影响。通过南海东部X井的实际钻探，一维核磁成果可以得到泥质束缚孔隙、毛管束缚孔隙、可动孔隙、渗透率等储层参数，二维核磁成果可以定性评价地层流体性质。二维核磁的储层评价和流体识别结果和实验室以及现场作业数据具有良好的一致性，具有非常强的实用价值。 |
| 英文摘要: |
| The buried hill igneous rocks in the eastern South China Sea are characterized by double porosity with complex lithology， using conventional logging data cannot quantitatively evaluate the reservoir and identify the fluid. The MREX 2D NMR （Nuclear Magnetic Resonance） logging instrument mainly measures the hydrogen signal in the formation pore fluid ， which is not affected by the rock skeleton. Through the actual drilling of well X in the eastern South China Sea， one-dimensional NMR results provide reservoir parameters such as muddy bound water porosity， capillary bound water porosity， movable porosity and permeability， while 2D NMR results can qualitatively evaluate formation fluid properties. 2D NMR reservoir evaluation and fluid identification results are in good agreement with laboratory and field data， proves， which provides strong practical value. |
