对我国东部某断块油田进行了地表化探详查研究．采用０．２５ｋｍ×０．２５ｋｍ测网，通过地表土壤介质的地化分析，确定了该油田长期以来悬而未决的油藏边界，建立了断块油气藏可能的异常模式，并从油气化探角度提出了对该油藏进行进一步钻探的合理化建议．该项试验成果表明，利用地表化探详查的方法确定我国东部断块油藏的边界和含油层分布是可行的．
A detailed study of the surface geochemical exploration of a fault block oilfield in eastern China. A 0.25km × 0.25km grid was used to determine the long-awaited reservoir boundary through the geochemical analysis of surface soil media. The possible anomaly patterns of fault-block reservoirs were established. Based on the geochemical analysis, Rationalize the reservoir for further drilling. The test results show that it is feasible to determine the boundary and oil-bearing layer distribution in eastern fault block reservoirs by the method of surface geochemical exploration.
