Abstract. Five seismic interpretation experiments were conducted on an area of interest containing a fault relay in the Snøhvit field, Barents Sea, Norway, to understand how interpretation method impacts the analysis of fault and horizon morphologies, fault lengths, and vertical displacement (throw). The resulting horizon and fault interpretations from the least and most successful interpretation methods were further analysed to understand the impact of interpretation method on geological modelling and hydrocarbon volume calculation. Generally, the least dense manual interpretation method of horizons (32 inlines (ILs) x 32 crosslines (XLs), 400 m) and faults (32 ILs, 400 m) resulted in inaccurate fault and horizon interpretations and underdeveloped relay morphologies and throw that can be considered inadequate for any detailed geological analysis. The densest fault interpretations (4 ILs, 50 m) and auto-tracked horizons (1 IL x 1 XL, 12.5 m) provided the most detailed interpretations, most developed relay and fault morphologies and geologically realistic throw distributions. Analysis of the geological modelling proved that sparse interpretation grids generate significant issues in the model itself which make it geologically inaccurate and lead to misunderstanding of the structural evolution of the relay. Despite significant differences between the two models the calculated in-place petroleum reserves are broadly similar in the least and most dense experiments. However, when considered at field-scale the magnitude of the differences in volumes that are generated solely by the contrasting interpretation methodologies clearly demonstrates the importance of applying accurate interpretation strategies.

地震解释方法对断层分析的影响：以巴伦支海Snøhvit油田为例

摘要。在挪威巴伦支海的Snøhvit油田中，在一个包含断层接替的目标区域进行了五次地震解释实验，以了解解释方法如何影响断层和地层形态，断层长度和垂直位移（投掷）的分析。进一步分析了从最小和最成功的解释方法得到的层位和断层解释，以了解解释方法对地质建模和油气量计算的影响。通常，最不密集的层位（32 inline（IL）x 32交叉线（XLs），400 m）和断层（32 ILs，400 m）的人工解释方法会导致错误的层位和层位解释不正确，中继形态不完善，可能导致投掷被认为不足以进行任何详细的地质分析。最密集的断层解释（4个IL，50 m）和自动跟踪的层位（1 IL x 1 XL，12.5 m）提供了最详细的解释，最发达的中继和断层形态以及地质上真实的投掷分布。对地质模型的分析证明，稀疏的解释网格在模型本身中产生了重大问题，这使其在地质上不准确，并导致对继电器结构演变的误解。尽管两个模型之间存在显着差异，但在最小和最密集的实验中，计算出的就地石油储量大致相似。然而，
