摘要:
油层在不同的水淹状况下会出现“L”型、“U”型、“S”型等复杂的岩电关系,水淹层测井精细评价的技术难点在于测井资料多解性和复杂性,导致没有统一的解释模型和解释标准。提出了能够更加真实地模拟油藏水驱油动态实时驱替过程的动态变倍数物质平衡法,利用该理论解释模型在准确计算地层混合液电阻率、含水饱和度、产水率等水淹层关键参数的基础上,结合两相渗流理论模型,分别计算储层在钻井液侵入校正前后的含水饱和度。结合动态变倍数物质平衡法和两相渗流理论的测井定量解释模型适合于不同水淹类型的测井精细评价,为建立统一的水淹层测井解释模型和解释标准奠定了理论基础。经研究区块60余口井实际测井资料的处理,水淹层测井精细解释符合率达86%以上,具有很好的推广应用前景。
Abstract:
Water-flooded oil reservoirs may show complex rock-electricity relations such as ‘L' type, ‘U' type and ‘S' type. It is difficult to finely evaluate water-flooded reservoirs using log data because of multiple solutions and complexity of log interpretation, so that no unified interpretation model and interpretation criteria have been established. In this paper, a variable PV material balance theory is proposed to simulate water-flooding process. Using the theory to build an interpretation model, the parameters related to a waterflooded layer are accurately calculated, such as resistivity, water saturation and water production, and then combining with a theoretical two-phase seepage model, water saturations before and after drilling mud invasion are calculated. The quantitative log interpretation model based on variable PV material balance theory and two-phase seepage theory is suitable for any water-flooded reservoir. It lays a theoretical foundation for establishing a unified log interpretation model and interpretation criteria. Applied in more than 60 wells in the studied block, the model provided interpretation results coinciding with actual results by over 86%. It is has a good prospect of popularization and application.
