Evaluation of the consolidation status of heavy oil sands through rock physics analysis: A case study from Fengcheng oilfield

Heavy oil is an important unconventional resource with huge availability worldwide, which also forms the primary source in Fengcheng oilfield, XinJiang, China. The elastic properties and consolidation status of heavy sands are significant values as they can provide guidance for reservoir exploration production. However, due to lack detailed rock physics investigation knowledge about their micro-scale still limited. Based on well log data laboratory measurements, we performed analysis sands’ properties. We first analyzed logs determine formations then quantitatively delineated relations between density, porosity, velocity. Combining measured data, applied theoretical models characterize sands. Our results show that this area poorly consolidated a loose frame. Overall, study highlights oilfield reveals status. It presents method integrating log, evaluate sands, facilitate future petrophysical information seismic characterization drilling risk evaluation.
