Sidaogou is the only locality to discover a little oil and gas in the exploration of the Hami Depression. Analyses of the formation conditions of the hydrocarbon pool, structural and reservoir features show that the Sidaogou structure had two periods of migration and accumulation of oil and gas. The first period of migration and accumulation came from the hydrocarbon formed in the source rock of the Sanbao Depression and formed the asphalt in the sandstone reservoir of Triassic and Jurassic in the Well Ha 2....

Sidaogou is the only locality to discover a little oil and gas in the exploration of the Hami Depression. Analyses of the formation conditions of the hydrocarbon pool, structural and reservoir features show that the Sidaogou structure had two periods of migration and accumulation of oil and gas. The first period of migration and accumulation came from the hydrocarbon formed in the source rock of the Sanbao Depression and formed the asphalt in the sandstone reservoir of Triassic and Jurassic in the Well Ha 2. The second period came from the hydrocarbon formed in the source rock of Triassic round about the Well Ha 2 and Ha 3 and formed the hydrocarbon pool in Sidaogou. The oil gas in the Sanbao Depression migrated and accumulated on a large scale after the rocks of the Xishanyao Formation of Middle Jurassic was deposited. The direction of migration was to east and northeast. In the end of the paper, the authors point out the primary reason for producing a little oil and gas in the Well Ha 2 and Ha 3 and the main direction for the future petroleum exploration.

四道沟低产油气藏是目前在哈密坳陷内钻探众多构造圈闭后所发现的唯一油气藏。通过对油藏构造、储层特征和油气成藏分析表明 ,四道沟构造存在二期油气运移与聚集 ,第一期形成类似哈 2井三叠系和侏罗系砂岩储层中的沥青 ,它来自三堡凹陷源岩生成的油气 ;第二期为四道沟构造上哈 2、哈 3井储层近源捕获的油气。三堡凹陷源岩在中侏罗统西山窑组沉积以后曾有较大规模的油气生成与运移 ,油气运移路线主要是向东或东北方向。储层物性差、裂缝不发育 ,早期油藏被破坏 ,后期油气源供给不足是四道沟构造上哈 2、哈 3井油气低产的主要原因。该地区下一步油气勘探应围绕三堡生油凹陷 ,以寻找未遭破坏的早期油气藏为勘探方向 ,以三叠系与侏罗系不整合附近的构造圈闭、地层圈闭、岩性圈闭和三叠纪古构造圈闭及裂缝发育带为主要勘探目标

High-production commercial natural gas was first found in well X-851 in the deep second member of Xujiahe Formation,Upper Triassic (T 3 x 2) in Xinchang gas field in the middle section of West Sichuan Depression.It is proved once again that the deep tight~ultra-tight sandstones in West Sichuan region are of the giant potential for natural gas exploration.A magnificent scene of the cubic exploration and development of various gas reservoirs with depths foom 300 m to above 4800 m has been truthfully formed...

High-production commercial natural gas was first found in well X-851 in the deep second member of Xujiahe Formation,Upper Triassic (T 3 x 2) in Xinchang gas field in the middle section of West Sichuan Depression.It is proved once again that the deep tight~ultra-tight sandstones in West Sichuan region are of the giant potential for natural gas exploration.A magnificent scene of the cubic exploration and development of various gas reservoirs with depths foom 300 m to above 4800 m has been truthfully formed in Xinchang gas field.According to the principle of natural gas organic geochemistry,the gas collected from well X-851 and its adjacent areas was studied by use of the carbon isotope and light hydrocarbon gas chromatogram methods.In combination with the data on regional geology and rock organic geochemistry,it is proposed in the paper that the mechanism of forming T 3 x 2 gas reservoir in Xinchang gas field is as follows:its gas source rocks include the black mudstones,shales and coal in T 3 x 2,its underlying Ma'antang,Formation and Xiaotangzi Formation;natural gas as a water-soluble phase migrated both from west to east and from bottom to top and beginning at the end of Late Triassic it was accumulated in the trap formed in Indo-Chinese epoch;and the reservoir's closed condition is composed of regional lithologic seal formed by overlying T 3 x 3,fluid pressure seal and concentration seal.Great significance of discovering high-production commercial gas in well X-851 in T 3 x 2 on deep exploration is expounded in the paper meanwhile and it is pointed out that the most beneficial region of prospecting T 3 x 2 gas reservoirs is the area including Xinchang structure and its west ending up at the piedmont of Longmenshan Mountains;and the study of the Indo-Chinese~Yanshan epoch palaeostructural trap and combination trap is especially important to the deep gas reservoir exploration.

川西坳陷中段新场气田首获深层上三叠统须家河组二段单井高产工业气流 ,再次证实了川西地区深部致密—超致密砂岩领域具有十分巨大的天然气勘探潜力 ,真正形成了新场气田从浅层 (30 0m)至深层 (4 80 0m)各种不同类型气藏立体勘探开发的壮观场面。本文从天然气有机地球化学角度入手 ,利用碳同位素和轻烃气相色谱方法 ,对X85 1井及邻区须二气藏天然气进行了研究 ,结合区域地质和岩石有机地化资料的分析 ,提出了对新场须二气藏形成机制的认识 :即以须二段自身和下伏马鞍塘、小塘子组黑色泥、页岩与煤为气源 ,天然气呈水溶相经自西向东和自下往上两个方向的运移 ,于晚三叠世末开始在印支期形成的圈闭中富集 ,由上覆须三段形成区域性岩性封盖和流体压力及浓度封盖而成藏。文中同时论述了X85 1井发现须二高产工业气流对勘探深层的重要意义 ,指出了新场及其以西至龙门山前区域是勘探须二气藏最有利的地区 ,印支—燕山期古构造圈闭和复合圈闭的研究对于深部气藏的勘探尤为重要。

The second member of Xujiahe Formation (Xu-2) is the principal exploration target in Upper Triassic in West Sichuan Depression and its major hydrocarbon source rocks belong to the underlying Ma'antang Formation-Xiaotangzi Formation.This series of hydrocarbon source rocks were deposited in a neritic shelf bay environment and the hydrocarbon source rocks are mainly composed of the marls,mudstones and shales of bay mudflat facies and coastal marsh facies.The types of organic matters are mainly Types Ⅰ and Ⅱ with...

The second member of Xujiahe Formation (Xu-2) is the principal exploration target in Upper Triassic in West Sichuan Depression and its major hydrocarbon source rocks belong to the underlying Ma'antang Formation-Xiaotangzi Formation.This series of hydrocarbon source rocks were deposited in a neritic shelf bay environment and the hydrocarbon source rocks are mainly composed of the marls,mudstones and shales of bay mudflat facies and coastal marsh facies.The types of organic matters are mainly Types Ⅰ and Ⅱ with a large hydrocarbon-generating potential,but the best hydrocarbon source rocks may be located under the nappe of Longmenshan Mountains.The Xu-2 reservoir had undergone two stages,i.e.oil-accumulating stage in Late Indo-China epoch and cracking gas-generating stage in Late-Middle Yanshan epoch.Early oil migration direction was the depression's updip stope where the diagenetic traps,lithologic pinchout traps,structural-diagenetic traps and palaeostructural traps of Indo-China epoch might be formed.The exploration success ratio of Xu-2 reservoir is mainly dependent upon the research on the types of traps and upon the breakthrough in the techniques of identifying traps.

川西坳陷上三叠统的勘探主攻目的层须家河组二段 ,其主要烃源岩为下伏马鞍塘—小塘子组。该套烃源岩沉积于浅海陆棚海湾环境 ,生烃岩石主要为海湾泥坪和滨岸沼泽相为主的泥灰岩、泥页岩。有机质类型以Ⅰ、Ⅱ型为主 ,生烃潜力巨大 ,最好的烃源岩可能位于龙山推覆带以下。须二段储层经历了印支晚期聚油和燕山中晚期裂解成气两个阶段。早期原油运移的有利指向是坳陷上倾斜坡 ,可形成成岩圈闭、岩性尖灭圈闭和构造成岩复合圈闭以及印支期古构造圈闭。须二段气藏勘探成败关键取决于圈闭类型研究和圈闭识别技术的突破
