The d 13C values of Lower Cretaceous Aptian-Albian platform-type carbonates in the Cuoqin Basin, North Tibet vary between 2.48 and 5.46. The mean value is 3.93. The values are not only provided with positive excursion, but also 1.17 higher than those of con-temporaneous pelagic carbonates which possess pretty high d 13C values. The origin is ap-proached. During the oceanic anoxic events, a great number of organisms were rapidly buried, causing the increase of the d 13C value of oceanic total dissolved carbon (TDC) and generally promoting the values of marine carbonates. After that, owing to the organisms undergoing dif-ferent isotopic fractionation in the paleo-ocean with stratified structure, d 13C values of shallow sea carbonate were obviously higher than those of pelagic carbonates.

The mother matter of Ordovician source are mainly sapropelic and generate oil in mature stage, since the high plants did not appear in Ordovician period, which is well known by internal and external scholars. Now we find a kind of Orodovician source rock generating mainly light oil and gas in mature stage during appraising source rocks in the Tarim Basin. The organic matters of this source rock are chiefly constructed by benthic brown algae in organisms (showing as macro algae), and are similar to humic source in hydrocarbon generation. The natural gas generated by this kind of source matters is obviously different from the sapropelic gas.

羌塘盆地有较广泛的膏盐岩层分布,主要赋存于中侏罗统雀莫错组、布曲组、夏里组和上侏罗统索瓦组中,具有亮晶鲕粒灰岩→白云岩(云灰岩)→膏盐岩层、粉砂岩(或泥岩)→膏盐岩→粉砂岩(或泥岩)→膏盐岩层和膏质白云岩(或泥岩)→膏盐岩层三... 详细信息

羌塘盆地有较广泛的膏盐岩层分布,主要赋存于中侏罗统雀莫错组、布曲组、夏里组和上侏罗统索瓦组中,具有亮晶鲕粒灰岩→白云岩(云灰岩)→膏盐岩层、粉砂岩(或泥岩)→膏盐岩→粉砂岩(或泥岩)→膏盐岩层和膏质白云岩(或泥岩)→膏盐岩层三种沉积层序,分属湖海湾型、潮坪和萨布哈型三种成因类型与沉积模式。湖型膏盐层较厚且展布稳定;潮坪型膏盐层较薄、变化快、层数多;萨布哈膏盐层呈薄层、极薄层夹于泥岩、白云岩中,也呈结核状、眼球状等,多发生表生水化变形。膏盐岩层除层状产出外,也呈盐丘产出,已在赤布张错、雁石坪、温泉等地多处发现盐丘构造,直径一般为100～1000m,并见有油气显示。因此,根据盐丘的发育情况,结合沉积相展布,在有利的构造部位寻找刺穿油气藏是大有可为的,应作为羌唐盆地油气早期勘探的突破点。

羌塘盆地是我国西部尚待进一步勘探与开发的最具前景的中、新生代大型含油气盆地。盆地内发育有10套烃源层,其中主要烃源层有4套,即上侏罗统索瓦组(J3s)、夏里组(J2.)、布曲组(J2.)和上三叠统肖茶卡组(T3x),除中央隆起带西部缺失外,在盆地其他地区有广泛分布,累积厚度大于3000m。主要烃源层由碳酸盐岩和泥质岩两类岩性组成,J3s和J2.主要为碳酸盐岩烃源层,有机质含量普遍不高,有机碳含量为0.15%～0.2.%,多属差—中等烃源岩。J3x和T3x主要是泥质岩烃源层,有机质含量较高,有机碳含量为0.6%～1.2.,属中等—好烃源层。此外,J2.和J3s还有一套油页岩烃源层,不仅有机碳含量特别高,而且可溶有机质也特别丰富,是盆地内最有价值的烃源层。4套主要烃源层均为海相沉积,有机物质以海相低等生物为主,形成以混合型(Ⅱ型)为主的有机质类型,具有较强的成烃能力。盆地中间有机质热演化处于成熟阶段,盆地周边和中央隆起带附近处于高成熟阶段,再向外达到了过成熟阶段。推测,盆地中部为原油分布区,向外扩展为凝析油湿气区,再向外为干气分布区。其中以索瓦组的原油分布范围最大,而自夏里组→布曲组→肖茶卡组,原油分布区的面积逐步缩小。盆地储集岩类有碎屑岩和碳酸盐岩以及少量火山岩。碎屑岩主要分布于上三叠统肖茶卡组三段?

It is discovered that carbon tetrachloride is a fluorescence quencher in crude oil detedion with cottings fluorologging. Hexane, which has many advantages as a substitute for carbon tetrachloride, is proposed. In this paper, four typical comparison results of fluorescence spectra of crude oil samples and some of field cores and cuttings are *** sensitivity of fluorescence analysis is increased by 10 to 35 times when we substitute hexane for carbon tetrachloride as the solvent of crude oil. We also find that the lighter the crude oil,the more Obvious the increase in analysis sensitivity. lt challenges the old concopt that coal-derived oil, condensate and some light oils do not emit fluorescence. The merit of hexane system in eliminating or reducing the fluorescent interference of modified asphalts in drilling fluids for cuttings fluorologging has also been discussed.

FILICOPSIDA is a predominant group of the Early Cretaceous floras of Northeast china, whichapproximates 100 species and accounts for more than one third of the floras. The majority ofthis group are of great importance and significance in stratigraphy. The previous studies ofthese ferns are mainly morphological, with only a few concerning the in situ spores andsporangia. In recent years. the authors have carried out a research project on the in situreproductive organs of the Early Cretaceous ferns from/ basins of Inner Mongolia, Liaoning,Jilin and Heilongjiang of Northeast china. The study focuses on 35 species of 17 genera be-longing to 10 families. The present note briefly introduces the results of this study by listingsome representative species.
