【摘要】 测井解释方法是发现油气层的有效手段。使用单一的电测井解释方法评价油气层 ,存在多解性。电测井与核测井、声测井或井壁取心组合解释 ,可以从电测井解释的油气层中识别出油层和气层。在我国油气勘探史上 ,就曾有过探井录井无气显示 ,而测井解释发现了气层的若干案例。文章通过探讨几个有代表性的案例 ,论述了测井解释发现油气层的颇有实用价值的方法和经验 ,为勘探家在新区、新层系和新领域发现油气层提供了依据 ,提高了我国天然气勘探的效益。更多还原

【Abstract】 Log interpretation methods are the effective means of discovering oil and gas reservoirs.Various conclusions may be obtained,when electric log interpretation method is only used for evaluating oil-gas reservoir.An oil reservoir,however,can be differentiated from a gas reservoir in the electric-log-interpreted oil-gas reservoir by a combination interpretation of the electric logging integrated with the nuclear logging and acoustic logging or sidewell coring.In the oil and gas exploration history of China there were many cases which gas show wasn′t being found in exploration well logging,but a gas reservoir was discovered by log interpretation at last.In the paper through analyzing several representative cases,the considerably useful methods and experiences of discovering oil and gas reservoirs by log interpretation are expounded and some bases are provided for the explorers to discover the oil and gas reservoirs in new areas,new strata and new realms,thus raising the beneficial results of natural gas exploration in China.更多还原
