Study of Formative Factors of Tianhe Central Commercial District A trap is one of the five essential requisites for a commercial accumulation of oil or gas. 广州市天河商业中心区形成机制探讨圈闭是石油和天然气形成商业性聚集的五大要素之一。
A trap is one of the five essential requisites for a commercial accumulation of oil or gas. 圈闭是石油和天然气形成商业性聚集的五大要素之一。
In the four aspects such as oil_rich depression, regional seal, lower_generating and upper_reservoiring structural_depositional condition and match between small uplift and big trap, the accumulation controls are analyzed for the Neogene oil reservoirs in Bohai Bay basin. 就富生油凹陷、区域性盖层、下生上储构造沉积条件和小凸起大圈闭配置等4项内容,分析了渤海湾盆地上第三系油藏的成藏控制因素。
The faulting effect had not only controlled trap forming, but also provided migration path and barrier for oil and gas migration; 断裂作用不仅控制圈闭的形成,还为油气运移提供了运移通道和油气藏遮挡条件;
Helium content in oil and gas reservoirs can be also used to determine when the trap was formed, providing a new method for the study of time-spatial distribution of the commercial oil and ags reservoirs. 还可用油气藏中的含氦量,确定圈闭形成期,为研究工业性油气藏的时、空分布提供了新的方法。
There is an obvious gravity positive abnormality under the nappe and it is possible that there are various types of hidden trap, which is the favourable target for oil and gas exploration. 在推覆体之下有明显的重力正异常,可能存在多类型的隐伏圈闭,是勘探油气的有利目标。
When the conventional trap geological model was being established in oil and gas evaluation systems, the "Generation, Reservoir, Sealing, Migration, Trap and Preservation" might be divided into three parts, I e ① the ability for entrapping oil and gas in trap; 油气评价系统中传统圈闭地质模型建立时的生、储、盖、运、圈、保可以分成三个层次:①圈闭获得油气的能力;
