查询词典 overmature

The results show that rising of groundwater levels after water transportation plays an important role in the decreasing in the crown loss of Populus euphratica, and the crown loss of Populus euphratica gradually increases with increasing distance from the river course. The trees crown loss was less than 10%, which mainly was distributed within 100 metres to each side from the river course. The proportion of crown loss of overmature and effete forests were 50%-75% within 200 to 400 metres.

The second period is the Fengcheng group high mature hydrocarbon in late Triassic to early Jurassic, which is the important exploration target. The third period is the Jiamuhe group overmature dry gas in the late Jurassic Period to the early Cretaceous.

五区南油气藏存在三期成藏，第一期是佳木河组过成熟干气和风城组成熟油气，成藏期在晚二叠世到早三叠世，在印支运动中期被破坏了，但是在保存条件好的地区仍存在这一期油气藏，它是勘探的对象之一；第二期是风城组高成熟油气，成藏期在晚三叠世到早侏罗世，也是勘探的对象之一；第三期是佳木河组过成熟干气，成藏期在侏罗纪到早白垩世。

Large condensate gas pools are developed in the Ordovician and Carboniferous in the Lunnan low salient. Geochemical study shows that the Ro of gas condensate in these gas pools is in the range of 0.8% 1.0%(far below the threshold of R o＝1.3％ for thermal cracking), and the condensate gas is overmature dry gas (with R o＞2.0%). Moreover, the crude oil and dry gas in the study area were charged in different stages, indicating that the genesis of the condensate gas was not thermal cracking.

轮南低凸起奥陶系及石炭系发育大规模的凝析气藏，地球化学的研究结果表明，这些凝析气藏中凝析油 Rc 在0.8%~1.0％（远低于热裂解成因 R o＝1.3％的门限），凝析气为过成熟干气（回归 R o＞2.0％）；同时，区内原油与干气的充注期相异，表明轮南地区的凝析气藏并非热裂解成因的产物。

The paper adopts some methods such as gas composition, carbon isotope, systematical analyzing and testing of reservoir bitumen biomarker from high evolutional natural gas and quantitative calculation of mixed gas, illustrates that natural gas from the section Ⅱ of Jialingjiang formation is mainly attributed to sapropel type organic matter gas of Permian, comes from carbonatite hydrocarbon rocks Permian which most of them are overmature, its main gas source has nothing to do with carbonatite hydrocarbon rocks of Jialingjiang formation themselves, presents in geochemistry characteristics of oil type cracked gas.

摘要通过对川中－川南过渡带西部的磨溪－潼南地区嘉二段天然气组成、碳同位素组成、高演化天然气储层沥青生物标志化合物的系统分析测试和混合成因气的定量估算，阐明了该区嘉二段天然气主要属于二叠系腐泥型有机质成因气，来源于二叠系过成熟为主的碳酸盐岩烃源，主力气源与嘉陵江组自身的碳酸盐岩烃源无关，并具有油型裂解气的地球化学特征。

The factors responsible for the gas richness in offshore Bohai are represen ted as follows:The thicker deposition sediments,it made the main source rock-Eoc ene Shahejie Formation reach overmature to generate gas;there is huge thickness of Oligocene source rock-Dongying Formation;there are strong Tertiary tectonic m ovements and high heat-flow in the offshore.

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.
