摘要

摘要: 不同断裂或同一断裂不同部位输导油气能力存在明显的差异。为了定量评价渤海湾盆地廊固凹陷大柳泉地区断裂垂向输导油气能力及其对油气分布的控制作用，在油源断裂厘定的基础上，综合考虑运移动力、油源供给及断裂运动学和几何学特征等多种因素对断裂输导能力的影响，总结出评价该区断裂垂向输导油气能力的4个地质参数，分别为断裂活动强度、异常压力、"中转站"规模和断裂凸面脊规模，这些参数与实际地质储量之间均具有良好的正相关关系，并以此作为定量化指标建立断裂垂向输导能力定量化公式。利用该公式对大柳泉地区断裂垂向输导油气能力进行评价，结果显示，断裂垂向输导油气能力定量评价结果与实际地质情况吻合度较高，表明该方法具有较好的适用性。

Abstract: The ability to transport oil and gas shows differences for different faults or different parts of the same fault. The vertical transportation of oil and gas through faults was evaluated quantitatively and the controls on oil and gas distribution in the Daliuquan area of the Langgu Sag of the Bohai Bay Basin were discussed. Various factors were considered including migration dynamics, hydrocarbon source, and the kinematics and geometric characteristics of faults.Based on confirming source faults, four geological parameters were summarized, including fault activity intensity, abnormal pressure, "transfer station" scale and fault convex ridge scale, all of which have a positive correlation with reserve abundance and can be used to fit a quantitative characterization formula of fault vertical transporting ability as quantitative indexes. Using this formula to evaluate the vertical fault transport ability of the Daliuquan area, this method indicates that the quantitative evaluation results are consistent with the actual geological conditions, which shows that the quantitative characterization method has a good applicability.
