【摘要】 据文安斜坡地质资料分析可知,文71-文安11构造带含油层系多,含油井段长,已探明的储量区块广,还有零散出油井点分布,勘探潜力较大。该区地质情况复杂,采用了滚动勘探并进行了潜力研究。从圈闭有效性的理论出发,结合文71-文安11构造带的实际地质情况,对研究区进行了深入的圈闭分析和评价,最终落实了21个有利圈闭,圈闭总面积69.6km2,并且优选了2个圈闭做了仔细地评价和分析,为下一步勘探布井和储量落实提供了有力的科学依据。更多还原

【Abstract】 It was known by analysis of geological data from Wen’an Slope that there existed many oil layers in Wen 71-11 tectonic belt,where oil layer was long,and its proven reserves was widely distributed,oil wells were scattered,exploration potential force was high.Because the geological conditions of the area was complicated,rolling exploration was used and potential force was researched.From the study of theoretical validity,according to an actual geological situation of Wen 71-11 tectonic belt,traps in the area are deeply studied and evaluated,21 favorable traps are determined with the total area of 69.6 km2,2 traps are chosen for a careful evaluation,it provides a powerful basis for next exploration well deployment reserves approval.更多还原
