The abundances of nearly 40 elements, Ir included, have been measured using radio-chemical and instrumental neutron activation analysis (RNAA and INAA) across a Devonian/Carboniferous (D/C) boundary section at Huangmao, Guangxi, china. The Ir anomaly has been found in the D/C boundary bed. Its peak value is 156 ppt, richer by a factor of 12 than that in the underlying strata. Besides, as with Ir, other siderophile and chalcophile elements such as Au. Ni. Co. As and Sb are also enriched. The cause for the abundance anomalies of Ir and other elemets is discussed. Neither volcanic eruption nor extraterrestrial impact can explain it satisfactorily. The real mechanism for the anomalies awaits further study.

Previous stratigraphic, lithologic and organic geochemical studies indicate that there are two sets of Paleozoic hydrocarbon source rocks in the Tarim basin, NW china, i.e., the Lower-Middle Cambrian and Middle-Upper Ordovician sequences. More and more hydrocarbons have been proved to be generated from the Middle-Upper Ordovician source rock. However, it is still unclear whether the Lower-Middle Cambrian source rock has generated

近 5 0年的油气勘探实践证明 :中国南方古生界的油气藏以晚期成藏最具工业价值。此一晚期成藏具有多期改造、破坏及重建的过程 ,多以后期改造和重建为主。后期改造主要包括重建封闭体系和油气相态的转化 ;重建的晚期油气藏则可能是不同成因、不同时期、不同类型油气在新的条件下重新聚集的结果 ,威远气田便是晚期成藏的典型代表。中国南方晚期油气成藏的决定因素是油气供给与构造的匹配关系 ,依此可划分出早生晚成型、晚生晚成型及重建型 3大类。目前 ,重建型的晚生油气藏应是中国南方古生界油气勘探取得突破的重要目标。

Source, reservoir, seal, preservation and potential of major petroliferous basins, Qinghai-Tibet plateau are analyzed in this paper. We conclude that (l) the hydrocarbon prospect of Qiangtang Basin is the best; (2) Cuoqin Basin has a relatively good hydrocarbon prospect; (3) Biru Basin, Qamdo Basin, Gamba-Dingri Basin have little hydrocarbon prospect, and (4) Kekexili Basin has little hydrocarbon prospect.

作者：赵庆飞中国石化石油勘探开发科学研究院北京100083

储采比是指一个国家、一个地区或一个油气田,在某年份剩余的可采储量与当年年产量的比值。通过储采比可以分析、判断油田所处开发阶段,稳产状况及其资源保证程度。如果储采比过大,会形成资金以储量存在的形式积压,储采比过小,产量保证... 详细信息

储采比是指一个国家、一个地区或一个油气田,在某年份剩余的可采储量与当年年产量的比值。通过储采比可以分析、判断油田所处开发阶段,稳产状况及其资源保证程度。如果储采比过大,会形成资金以储量存在的形式积压,储采比过小,产量保证程度低。研究了油田不同开发阶段储采比的变化规律以及稳产阶段储采比的界限值;根据储采比在不同开发阶段中的要求,研究了规划产量下所需新增的可采储量。最后,分析了中石化及所属油区的储采比现状及变化趋势。

The purpose of this paper is to discuss the poly-phase salt tectonics and its relation to the hydrocarbon accumulation of the Tarim superimposed basin. Several salt sequences are developed in the Tarim basin, they are: (1) the Mid-Early Cambrian salt sequence, mainly distributed in the west part of the north Tarim uplift and Keping uplift; (2) the Early Carboniferous salt sequence, mainly distributed in the south slope of the north Tarim uplift; (3) the Paleogene salt sequence, mainly distributed in the mid-west part of the Kuqa foreland fold belt and north Tarim uplift; and (4) the Miocene salt sequence, mainly distributed in the east part of the Kuqa foreland fold belt. The salt sequences deposited in the tectonically calm scenario, while the salt layers deformed during the period of intense tectonism. Although the salt sequences are characteristic of plastic flow, the differences of salt deformation styles exist in the different salt sequences be-cause of the different deformation mechanism. It is attractive that the distribution of the large oil-gas fields or pools has a bearing upon the salt sequences and salt structures, such as the Tahe oilfield related to the Lower Carboniferous salt sequence and laterally facies changed mudstone, the Kela No.2 gas field to the Paleogene salt structures, and the Dina gas field to the Miocene salt structures. It is indicated that the large-scale hydrocarbon accumulation is con-trolled by the poly-phase salt sequences and structures. The deep analysis of the poly-phase salt tectonics is helpful to understanding the characteristics of the structural deformation and oil-gas accumulation of the Tarim basin.
