Ancient Lateral Sealing Evaluation Method of Fault and Its Application in Hydrocarbon Accumulation Period
-
摘要: 油气成藏期断层古侧向封闭能力的强弱对于油气的聚集和分布有着重要的影响,目前尚无有效的评价方法用于定量分析断层古侧向封闭性,并且在利用断层侧向封闭油气SGR(Shale Gouge Ratio)下限方法预测油柱高度过程中,发现断层侧向封闭油气能力与油气分布呈现部分不吻合现象,即井在预测范围之内,但是该井却不含油气.经过深入研究表明:这种现象可能是由于在油气成藏期断层古侧向封闭能力弱(达不到侧向封闭油气下限)造成的.因此,在断层侧向封闭油气SGR下限方法的基础上,通过恢复油气成藏期的古地层厚度、断层古断距、古泥质含量曲线,建立一套断层古侧向封闭性的评价方法,并以冀中坳陷文安斜坡文13断圈为例,利用断层古侧向封闭性评价法对断圈的古侧向封闭能力进行定量评价.结果表明:文13断圈在油气成藏期侧向封闭油气高度为0 m,与井试油结论相吻合,表明该方法用于定量评价断层古侧向封闭性是可行的,对于准确评价断圈封闭油气能力、降低断圈油气钻探风险以及丰富和完善断层侧向封闭理论均具有实践和理论意义.Abstract: The ability of fault lateral sealing has an important influence on the accumulation and distribution of oil and gas in hydrocarbon accumulation period. However, fault sealing can only be evaluated by the method of lateral sealing of the lower limit at present. Moreover, it is found that find lateral sealing ability of fault and distribution of oil show some inconsistencies in the evaluation process in which wells located in the range of forecast turn out not contain oil and gas. It is found in this study that this phenomenon may be due to the weak ancient lateral seal ability of the fault in the hydrocarbon accumulation period. Therefore, an evaluation method of ancient lateral sealing evaluation metnd of ancient lateral sealing evaluation method of fault is proposed on the basis of the SGR (Shale Gouge Ratio) threshold method of the fault lateral seal, oil and gas, restoring the ancient strata thickness, the ancient fault throw, and the ancient shale content curve in the hydrocarbon accumulation period. This paper selects Wen13 fault trap in the Wenan slope of Jizhong depression as an example, and the fault trap lateral sealing ability is quantitatively evaluated by the ancient fault lateral sealing evaluation method. The results show that the lateral seal hydrocarbon height of the Wen13 fault trap is zero meter, in conformity with the well test results, which indicates that the evaluation method of the ancient fault lateral sealing ability is feasible. For accurate evaluation of the ability of seal hydrocarbon in the fault trap, it is of practical and theoretical significance to reduce the hydrocarbon drilling risk of fault trap, to enrich and perfect the fault lateral seal theory.
