Therefore, established a finite element Stable response model of a horizontal whole string and carried out t the safety varied frequency of gas well after researched the natural seriously transversal vibration and compressional vibration frequency range of tubing string with packer and packerless, so that it make the tubing string to avert the covibration frequency range of natural gas excited.

本文认为以某井高产量稳产时，天然气对油管柱的外激励为简谐激振，因此研究中建立某水平井全井段油管柱稳态响应的有限元力学模型，并获得了在无封隔器和有封隔器情况下的油管柱发生严重横振和纵振的频率范围，提出了天然气安全调节频率范围，使油管柱避开可能引起严重破坏的天然气激励频率区域。

The paper studies fault diagnosis technology based on fruticose gas pipe network which is universal in small towns,and gives a particular description of domestic and foreign gas pipe network fault diagnosis technique based on hardware and software currently. The author uses graph theory to build up hydraulic analysis model of natural gas network and presents its solution methods. Besides, the author works out the relation between gas pipe pressure and flux in unsteady condition of fluid flow according to pressure boundary condition and differential equation group, and puts forward fault diagnosis methods and steps of the fruticose natural gas pipe network of middle pressure based on the simplification of this relation.

The differences in reservoiring conditions of natural gas and oil, as well as the multicycle developments and evolution histories of major gas bearing basins in China, and the geological environments characterized by relatively active tectonic movements in later period have resulted in the forming conditions of gas fields in China to be more complicated than those in many basins all over the world.

由于天然气与石油在成藏条件上的差异和中国主要含气盆地多旋回的发展演化历史、晚近时期构造运动比较活跃的地质环境，中国气田形成条件较世界上许多盆地复杂和成藏类型较多。总结中国大中型气田的成藏历程，可以新近纪、古近纪和中生代为界将气田的形成归为 4类：1超晚期生烃成藏型；2晚期生烃成藏型；3早期生烃聚集和晚期定型成藏型；4早期生烃成藏型。在这 4类中，以晚期和超晚期成藏和定型为主且分布最广、天然气前景最好、是中国天然气最主要富集领域。早期生烃成藏型在保存良好的盆地也有较好的前景。

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。
