油气微运移方向与圈闭有效性及其控藏模式——以济阳坳陷勘探实践为例
|
摘要
油气的二次运移方向可以分为2种:一种是从烃源灶到正向构造带的宏观运移方向,适用于有利勘探区带的预测;另一种是近圈闭处的微运移方向,适用于有利勘探目标的评价。利用济阳坳陷多口失利探井的勘探实践资料总结发现,在油气宏观运移方向明确的前提下,相邻2套地层等高线的组合关系决定圈闭的有效性及成藏位置。当断层两盘构造等高线近于平行、断层走向与等高线(近于)平行,则上、下两盘的圈闭都有成藏的可能性。当断层两盘构造等高线近于垂直,近油源一侧(下降盘)等高线与断层走向(近于)平行时,则邻近油源一侧的圈闭可以成藏。这一控藏模式的总结,为研究人员开展勘探目标评价提供了依据,有利于提高探井成功率。
Directions of secondary hydrocarbon migration can be divided into two categories: one is the macro-migration from hydrocarbon kitchen to positive structural belt, which can be used to forecast favorable exploration zone; the other one is micro-migration direction near trap, which can be used to evaluate favorable exploration targets. Using the exploration practice of several failure hydrocarbon exploration wells, this paper summarizes, under the precondition of the macro-migration direction, the composition relationship of adjacent layers stratigraphic contour lines to decide the efficiency of the traps and accumulation location:when the structural contours of the two sides of the fault are nearly parallel or the strike of the fault is parallel to the contours, the traps on both sides of the fault are likely to form reservoirs; when the structural contour lines on both sides of the fault are near vertical and the contour lines on the side near the oil source(descending wall) are parallel to the strike of the fault, the traps on the side near the oil source can form reservoirs. The summary of this reservoir control model provides a basis for researchers to carry out exploration target evaluation, and is conducive to improve the success rate of exploration wells.
