深南构造带滚动勘探潜力综合评价研究
|
摘要
深南背斜是深县凹陷南部的一个塌陷背斜,其构造面积120km2,探明原油地质储量1300×104t。本区有良好的石油地质条件,已发现了一定规模油气藏。由于该区构造复杂,地震资料品质较差,圈闭落实程度较低,已发现的油藏纵向上具含油层位多、油水间互等特点,影响了勘探开发成效。
此次研究,通过区域构造重新解释和分析,归纳了深南构造带的断裂结构特征,断层在平面、纵向上的分布规律,及其对油气藏聚集的控制作用;通过沉积相、沉积微相以及垂向微相叠置组合模式研究,分析了油砂体的控制因素,并进行了油砂体的分类评价。结合以上的研究成果,对构造带的油气聚集规律进行了分析归纳,认为研究区的构造背景控制油气富集趋向,横向上受沉积相、油源断层所控制,油源断层与分枝断层控制油气分布,侧向封堵条件决定了圈闭内油气富集程度;沉积相与构造控制了油层发育及其储集性能,砂体类型影响油层分布形态,馆陶组油藏受断裂控制作用明显,油藏主要发育于切割深度大、活动强度相对比较剧烈的断裂带附近。最终将研究结论与探井资料相结合,在已开发区周缘寻找新的含油断块,落实了更多的优质储量,指出了多个有利勘探目标,为下一步滚动勘探提供了建议。该研究成果对于深南构造带油气藏的进一步滚动勘探具有指导意义。
Shennan Structural Belt, a collapse anticline located in the south of Shenxian depression, with 1300×104t of oil reserve,the total area of the anticline is 120km2. Shennan anticline has good petroleum geological conditions, where sizable reservoirs have been discovered. In this area, the structures are complex, seismic data attributes are poor, trap materialization level is low, the reservoirs discovered have the characteristics of multiple oil - bearing zones with aquifers interbeded, thus the effectiveness of exploration and development are restricted.
Based on the analysis and research of the regional structure, its characteristics and distributing configurations in horizontal and vertical orientation and the functions of controlling and adjusting the reservoirs are summed up. The factors of controlling oil sand body have been analyzed by the study of combinations of sediment phase,sedimentary microfacies and its vertical overlaps; the body of oil sand were categorized and evaluated. With the research fruits mentioned above the rules of gathering oil and gas towards the structures has been summarized as that the structure grounds control the trends of oil and gas gathering mainly, that sediment phase and the fault of oil source restrict the trends transversely. The distribution of oil and gas was dominated by the fault of oil source and its branches. The degree of oil and gas gathering depends on the blocking condition in side way, the development of oil layers and gathering abilities are under the control of sediment phase and its structure. Its distribution patterns of oil layers are affected by the pattern of sandy body. Oil reservoirs in GUAN TAO GROUP are restricted by rupture obviously. Mainly oil reservoirs developed in and near deep faults with comparatively extensive movements.Finally, combining the research results and the data of probing well, the new block of containing oil will be searched in the verge of the developed block, the more reserves in high quality will be fulfilled and profitable exploration aims will be pointed out, suggestions on the next progressive exploration will be offered as reference. This result will direct the further progressive exploration in the reservoirs of Shennan structure belt.
