摘要
砂砾岩稠油储层具复杂孔渗性和非常规流体特性,这使得对其测井解释异常困难。多矿物分析测井解释方法能有效利用该类储层的各种测井信息,并较准确地求取储层参数。JMSR地区的储层主要为砂砾岩,矿物组分较多。采用多矿物模型最优化方法计算出储层的孔隙度和各种矿物组分的含量,并利用Scheidger公式计算出渗透率,结果表明,计算出的数值及变化趋势与岩心分析结果吻合较好。利用泥浆侵入信息,并结合油气显示结果识别稠油储层,可有效提高测井解释符合率,为科学、合理地开发JMSR地区的稠油油藏提供了比较可靠的依据。
The log interpretation for glutenite heavy oil reservoir is difficult because of its complexity of porosity and permeability and its special fluid property. Multi-mineral log interpretation method can effectively utilize all kinds of logging information to get reservoir parameters accurately. The reservoir JMSR area is mainly of glutenite with complex mineral composition. By using multi-mineral model optimization method, we obtained the porosity and mineral composition content and computed the permeability with Scheidger formula, and the results are in accord with the actual core data. The multi-mineral log interpretation method can be used to recognize heavy oil reservoirs by computing mud invade depth, can increase interpretation coincidence rate and provide dependable data for exploitation in JMSR area.
