Jiyang Depression In Dongying Sag River 60 Fault Block Structures And Hydrocarbon Enrichment Patterns

In the course of petroleum exploration and development, the rule ofthe oil accumulation/distribution attracts so much attention that it hasbecome one of the most conceming highlights. In this paper, it has beenstudied in our subject-the He-60 blocks, belong to Dongyingdepression, Jiyang sag in the eastem China, whose block structures havebeen taken into account as well as whose accumulation rules; and thefollowing techniques such as the oil description methods, thedata-combination use of the composing log, three-dimension seism, thedrilling well and the dynaminc one are taken in our study of the rule ofthe oil accumulation/distribution.Based on the reservoirfine-partition/contrast of S₁ and S₂, we have a synthetic study on thedistribution, the structure character and the fine facies of the destinationreservoirs.What is more, with the help of analysis of the relation betweenoil and water, the distribution of reserves; the accumulation rules of the oilcan be disclosed.
