核磁共振技术在留416断块二次开发中的应用

Application of Nuclear Magnetic Resonance Tech in the Second Development for Liu416 Faulted Block.

针对留416断块开发中出现的注不进、采不出等问题,采用低磁场核磁共振T2谱技术和高磁场核磁共振成像技术对该断块留416-8井储层岩石特征和流体特征进行分析实验。应用实验结果,初步认清了油藏复杂的地质条件,并采用相应的开发对策,解决了实际问题,提高了油藏整体开发水平。实验表明,对相应储层采用核磁共振测井技术测量储层孔隙度、可动流体、渗透率等参数是可行的,该技术对储层非均质性差、流体性质差的油藏治理具有较强的指导意义。

To the problem of not being injected and not being extracted in development of Liu416 faulted block, analysis and experiment using nuclear magnetic resonance T2 spectrum tech of low magnetic field and nuclear magnetic resonance imagine tech of high magnetic field has been conducted to the features reservoir rock and fluid in Liu416-8 well of this block. By means of the results,complex geology condition has been known briefly and actual problem has been solved by corresponding developing strategy to rise up the whole developing level. The test shows that utilizing nuclear magnetic resonance logging tech for corresponding formation to measure parameters of porosity,flowing fluid, permeability is feasible and the tech has the guidance for harnessing the reservoir with bad heterogeneous property and fluid property.
