Integration Study of Reservoir Rock Typing and Reservoir Prediction in TM Oil Field

Abstract

Reservoir rock typing and reservoir prediction are very important in reservoir characterization. Understanding the distribution of different types of reservoir plays an important role in successful prediction of reservoir performance. This paper focuses on the integration study of rock typing and reservoir prediction. A detailed workflow has been demonstrated through a case study for a highly heterogeneous reservoir in TM oil field. Three different reservoir types have been distinguished by their distinct storage and flow capacity characteristics summarized from mercury injection capillary pressure curves and combining rock-pore-throat size distribution curves. Acoustic impedance of these three different types of reservoirs has been analyzed, and their distribution characteristics have been predicted through geostatistical inversion calibrated by core and logging data. All this provide an effective and perspective geological reference for reservoir characterization in TM field. And it also can be used in other similar reservoirs.
