Main Controls on Hydrocarbon Accumulation in the Paleozoic in Central Saudi Arabia

petroleum Science 2007年第2期4卷 10-17页

作者： Bai Guoping (key laboratory for Hydrocarbon Accumulation under ministry of education, China University of petroleum, Beijing 102249, China) China Univ Petr Key Lab Hydrocarbon Accumulat Minist Educ Beijing 102249 Peoples R China

Sandi Arabia is renown for its rich oil and gas Mesozoic. However, the discovery of Paleozoic fields in resources with the bulk of the reserves reservo/red in the the late 1980s has encouraged further exploration in the Paleozoic. This paper reviews the salient features of the Paleozoic petroleum geology in central Saudi Arabia and discusses the main factors controlling hydrocarbon accumulation in the Paleozoic. The Lower Silurian Qusaiba hot shale is the principal source rock for the hydrocarbons discovered in the Ordovician to Permian reservoirs. Of them, the Permo- Carboniferous Unayzah and Upper Ordovician Sarah Formations have the best exploration potential. The key factors controlling hydrocarbon accumulation in the Unayzah Formation are migration pathways and reservoir petrophysics. The key factors controlling hydrocarbon accumulation in the Sarah Formation are reservoir petrophysics and the development of structural traps.

OBJECTIVE: To investigate the antidepressant-likeeffect of active fraction of Polyrhachis vicina Roger(AFPR) in a rat depression model, and to elucidate the underlying ***: AFPR was extracted with ethanol followed by petroleum ether. Its antidepressant-like effect was investigated in mice by tail suspension test(TST), forced swimming test(FST) and open field test(OPT). A repeated dose of reserpine(0.5 mg/kg, daily for 14 d) was used to establish a rat depression model. Fluoxetine was used as positive control agent. The effect of AFPR on reserpine-induced ptosis, hypothermia and akinesia, the levels of monoamines and their metabolites, and the activity of monoamine oxidase(MAO) in hippocampus and prefrontal cortex were ***: Administration of AFPR by gavage at 160 and 320 mg/kg significantly reduced the duration of immobility in the FST and TST, and did not affect locomotor activity in the OPT. In the reserpine-induced depression model, AFPR attenuated anhedonia, demonstrated by reversing hypothermia, akinesia and sucrose consumption. AFPR significantly increased the concentration of monoamines, including dopamine, serotonin, noradrenaline and ***: AFPR normalized the metabolism rates of noradrenaline, serotonin and dopamine,and the activity of MAO, which were altered by chronic reserpine exposure. The findings suggest that modulation of the monoaminergic neurotransmitter system likely underlies the antidepressant-like effect of AFPR.

鄂尔多斯盆地上三叠统延长组长73砂层组大规模发育自然伽马测井值大于180API、浊流沉积的粉砂级-细砂级高自然伽马砂岩,由于长期以来自然伽马等常规测井系列将其识别为“油页岩等优质烃源岩”,为此开展了其分布预测研究。通过盆地长73砂层组沉积特征、岩性特征、测井特征以及高自然伽马砂岩高放射性成因的分析,认为深部热水活动携带的 Th、U等放射性元素可能形成了长73砂层组平面上放射性相对高值区且相对高值区内高自然伽马砂岩常大量发育,导致长73砂层组本应在平面上具有连续形态的浊流沉积砂体,而在根据自然伽马等常规测井系列识别上呈现出“平面上不连续的形态”,但可根据“平面上不连续的浊流沉积砂体形态”预测出浊流沉积砂体平面上可能具有的连续形态,显然平面上预测出的连续砂体形态部位为高自然伽马砂岩大量发育区。勘探开发实践表明,上述方法对长73砂层组高自然伽马砂岩的预测快速有效。
