| 1 | 运用排替压力法定量预测断层侧向封闭能力——以济阳坳陷为例显示文摘断层对油气的封闭作用主要体现在侧向封闭上,而断层岩的排替压力是评价断层侧向封闭的主要参数,泥质含量和埋深则是影响岩石排替压力的主要因素。断层岩的泥质含量或埋深越大,其排替压力越大,对油气的封堵能力越强。通过实验测试手段可以建立不同泥质含量断层岩的排替压力与埋深的关系,从而可以实现对断层岩排替压力的预测。断层岩与储层的排替压力差决定了断层封堵油柱高度的大小,压差越大封堵的油柱高度越大,两者具有较好的正相关性。因而通过两者的相关关系可以建立断层岩封堵油藏油柱高度的顶底界预测模型。实际应用结果表明,通过排替压力预测断层岩的封闭能力是可靠的。 | 宋国奇 向立宏 郝雪峰 尚冰 宁方兴 黄蓉 | 2011 | 油气地质与采收率2011，18，1： | 25 |
| 2 | 断层两盘裂缝发育特征及其石油地质意义显示文摘根据野外地质调查、构造物理模拟和地质综合分析,对陆相断陷盆地中断层两盘裂缝发育特征及其石油地质意义进行了研究。断裂带包括断裂破碎带和裂缝发育带,断层两盘的裂缝发育程度存在着明显的差异,断裂主动盘张裂缝密度大于被动盘,有些断裂被动盘裂缝根本就不发育。在陆相断陷盆地中,处于被动盘的反向断层控制的圈闭更容易形成油气藏。 | 宋国奇 刘克奇 | 2009 | 油气地质与采收率2009，16，4： | 24 |
| 3 | 惠民凹陷临盘油区断裂胶结带基本特征及形成机制显示文摘惠民凹陷临盘油区断块油田广泛发育,但对其封闭机制认识不清.从临盘复杂断块油田的实际地质资料出发,依据岩心、测井资料,结合物性、扫描电镜等实验分析,探讨了断裂胶结带的基本特征和形成机制.研究表明,临盘油区富含钙镁离子的地层水在断裂活动过程中沿断裂向上流动,随着压力的降低导致在断层附近砂岩中易形成方解石、白云石等矿物的沉淀,从而形成了致密的断裂胶结带,胶结带内孔渗性急剧变差,喉道半径和渗透率约降低一个数量级,成为封堵油气的有利屏障. | 刘金 宋国奇 郝雪峰 宿春梁 刘克奇 | 2011 | 地球科学(中国地质大学学报)2011，36，6： | 7 |
| 4 | Improvements to the fuzzy mathematics comprehensive quantitative method for evaluating fault sealing显示文摘Fuzzy mathematics is an important means to quantitatively evaluate the properties of fault sealing in petroleum reservoirs.To accurately study fault sealing,the comprehensive quantitative evaluation method of fuzzy mathematics is improved based on a previous study.First,the single-factor membership degree is determined using the dynamic clustering method,then a single-factor evaluation matrix is constructed using a continuous grading function,and finally,the probability distribution of the evaluation grade in a fuzzy evaluation matrix is analyzed.In this study,taking the F1 fault located in the northeastern Chepaizi Bulge as an example,the sealing properties of faults in different strata are quantitatively evaluated using both an improved and an un-improved comprehensive fuzzy mathematics quantitative evaluation method.Based on current oil and gas distribution,it is found that our evaluation results before and after improvement are significantly different.For faults in‘‘best’’and‘‘poorest’’intervals,our evaluation results are consistent with oil and gas distribution.However,for the faults in‘‘good’’or‘‘poor’’intervals,our evaluation is not completelyconsistent with oil and gas distribution.The improved evaluation results reflect the overall and local sealing properties of target zones and embody the nonuniformity of fault sealing,indicating the improved method is more suitable for evaluating fault sealing under complicated | Da-Wei Dong Ji-Yan Li Yong-Hong Yang Xiao-Lei Wang Jian Liu | 2017 | Petroleum Science2017，14，2： | 3 |
