鄂尔多斯盆地蟠龙油田长6油藏形成条件研究程度低,勘探成效欠佳。虽然在蟠龙油田南部沙则沟地区获得长6油层突破,但在油田中部和北部,均未有长6油层组发现。研究表明,长6油藏形成地质条件优越,因此,长6油层组石油勘探潜力仍然很大。通过全面而系统地分析和总结沙则沟地区长6油层组勘探经验,研究石油运聚成藏规律、加大勘探力度,相信不久后中部低勘探程度地区长6油层组的勘探定会取得进展。%Low-degree investigation on forming conditions of Chang-6 reservoir of Panlong oilfield in Ordos basin results in unsatisfied result of petroleum exploration.Except for finding out Chang-6 reservoir in Shazegou area in southern Panlong oilfield,this reservoir has not been found in the middle and north parts of this oilfield,showing that the potentials of petroleum exploration of Chang-6 reservoir are still very big.Studies show that the forming conditions of Chang-6 reservoir are advantageous.This paper comprehensively and systematically analyzes and summarizes the exploration experiences of Chang-6 reservoir in Shazegou area,and suggests that to further study its lows of petroleum migration and accumulation,and increase the exploration efforts,the exploration of Chang-6 reservoir in the middle part of this oilfield will make progress soon.
