油气沿断裂垂向倒灌运移最大深度的研究方法及其应用
|
摘要
油气沿断裂垂向倒灌运移深度研究一直是上生下储式生储盖组合油气勘探研究的关键问题。为了定量研究油气沿断裂垂向倒灌运移的最大深度,在油气沿断裂垂向倒灌运移所需动力条件及最大深度影响因素研究的基础上,通过源岩古超压值与油气沿断裂垂向倒灌运移深度之间关系,确定油气沿断裂垂向倒灌运移所需的最小源岩古超压值(或油气沿断裂带运移阻力),由油气沿断裂垂向倒灌运移所需的动力条件,建立了一套油气沿断裂垂向倒灌运移最大深度的研究方法,并将其应用于松辽盆地三肇凹陷青一段源岩生成油沿断裂向下伏扶杨油层垂向倒灌运移的研究中,结果表明:三肇凹陷青一段源岩生成油沿断裂垂向倒灌运移最大深度最大可达到400 m以上,主要分布在其东部边部树119井、西部边部肇13井、北部边部宋深1井和凹陷中心4个局部地区,由4个高值区向其四周青一段源岩生成的油沿断裂垂向倒灌运移的最大深度逐渐减小,在凹陷中北部和凹陷边部减小至100 m以下,与目前三肇凹陷扶杨油层已发现油底深度分布基本吻合。表明该方法用于定量研究油气沿断裂垂向倒灌运移最大深度是可行的。
Objectives: The quantitative study methods and its application of the depth of oil and gas vertically downward migration along faults is the key to oil and gas exploration in the upper generation and lower accumulation pattern of petroliferous basin. To study the quantitative study methods of the maximum depth of oil and gas vertically downward migration along faults.Methods: Based on the relationship between paleo-overpressure of source rocks and the depth of vertically downward oil and gas migration along faults,the paleo-overpressure minimum source rock needed for vertical downward and migration along faults of oil and gas was determined( or the resistance of oil and gas migration along fault zones). Based on the dynamic conditions required for oil—gas vertical inversion and migration along faults,we found a series of research methods of the maximum depth of oil and gas vertically downward migration and apply it to a source rock formation vertically downward migration along faults.Ressults: It turned out that the maximum depth of vertically downward migration along faults of a source rock formation in Sanzhao depression of Songliao basin can reach 400 m,which mainly distributed in four local areas:Shu119 well in the eastern margin,Zhao 13 well in the western margin,Songshen 1 well in the northern margin and the center of sag.Conclusions: The maximum depth of the vertical downward migration along faults of the oil from the four highvalue areas to the surrounding rocks of Qing1 Member to the periphery gradually decreased and is reduced below100 m in the northern and the edge of depression,which is basically match with the depth distribution of current found bottom oil layer in Fuyang reservoir of Sanzhao depression. This indicates that it is feasible to use the method to quantitatively study the maximum depth of oil and gas vertically downward migration along faults.
