The reasonable improvement of the lean oil technics in crude benzene tower and heat exchanger of lean and fat oil is introduced according to the practical conditions after reconstruction.
分析了浮头式列管换热器的故障现象及产生原因,提出改造方案,并根据改造后的实际情况将脱苯塔和贫富油换热器部分的贫油工艺进行了合理改进。
Despite their long history of development, some oil-rich sags still have a large quantity of residual resource in the forms of five potential play targets: undeveloped sags in the developed depression, hidden reservoir, complex fault structure, and deeply buried and small hills and some special reservoirs.
冀中坳陷历经多年勘探,但富油凹陷之间、不同构造单元或区带之间、不同勘探层系之间以及不同勘探领域之间的勘探程度仍明显不均衡,而富油凹陷勘探程度尽管较高,但剩余油气资源还很丰富,存在老区新凹陷、隐蔽油藏、复杂断裂带、深潜山和小潜山及潜山内幕、特殊类型油藏等5大勘探接替领域。
Based on the research and exploration of lithostratigraphic reservoir in the Jizhong depression of the Bohai Bay basin and Erlian basin, the hydrocarbon distribution in a continental oil-rich sag has "complementarity" feature, viz.
渤海湾盆地冀中坳陷和二连盆地岩性地层油气藏研究和勘探实践发现,富油凹陷油气分布具有“互补性”特征,既构造和岩性地层油气藏在油气资源分配、空间分布上具有“互补性”,这种分布特征是由构造与岩性地层油气藏所赋存的宏观地质背景、成藏条件、成藏机理等多种因素的耦合所决定的。
