抽油井分层测压技术及其应用

尕斯库勒油田位于青海省柴达木盆地西部南区的尕斯断陷亚区红柳泉跃进一号断鼻带上的一个三级构造,位于狮子沟——油砂山大逆断层下盘,石油地质储量7200多万吨,目前,尕斯库勒油田已步入中后期开发阶段,由于开采的各小层间和层内地质特征的差异(如各小层地层压力、渗透率、孔隙度等物性的不同),在油田注水开发后,地下水线推进速度相差很大,致使油井见水时间、含水率及各分层的出力状况相差悬殊,严重时甚至非主力层出力甚微或根本不出力,多层合采时的产量远远低于分层开采时的产量之和,从而制约了油井生产寿命,严重影响了油田的长期稳产。因此…

SHRIMP zircon U-Pb dating for volcanic rocks of the Dasi Formation in southeast Hubei Province, middle-lower reaches of the Yangtze River and its implications

The Jinniu Basin in southeast Hubei,located at the westernmost part of middle-lower val-ley of the Yangtze River,is one of the important vol-canic basins in East China. Volcanic rocks in the Jin-niu Basin are distributed mainly in the Majiashan Formation,the Lingxiang Formation and the Dasi Formation,consisting of rhyolite,basalt and basaltic andesite,(trachy)-basalt and basaltic trachy-andesite and (trachy)-andesite and (trachy)-dacite and rhyolite respectively,in which the Dasi volcanism is volumet-rically dominant and widespread. The Dasi volcanic rocks were selected for SHRIMP zircon U-Pb dating to confirm the timing of volcanism. The results indi-cate that there exist a large amount of magmatic zir-cons characterized by high U and Th contents in the volcanic rocks. The concordia ages for 13 points are 128 ± 1Ma (MSWD = 3.0). On account of the shape of zircons and Th/U ratios,this age is considered to represent the crystallization time of the Dasi volcan-ism. The volcanic rocks in the Dasi,Majiashan and Lingxiang Formations share similar trace elementand REE partition patterns as well as Sr-Nd isotopic compositions. In combination with the regional geol-ogy,it is proposed that the southeast Hubei volcanic rocks were formed mainly during the Early Creta-ceous,just like other volcanic basins in middle-lower Yangtze valley. A lithospheric extension is also sug-gested for tectonic regime in this region in the Cre-taceous Period.     

Growth ages of ferromanganese crusts from the western and central Pacific： Comparison between nannofossil analysis and ^10Be dating

Based on results of nannofossil analysis and 10Be dating in ferromanganese crusts M1-1 and A1-1 (no nannofossils were found in it),from the western and central Pacific respectively,it is found that the crust growth ages from nannofossil biostrati-graphy agree well with those based on 10Be isotope analysis. Both crusts have three growth layers,and the oldest layer was deposited in Miocene at about 12.80 Ma. The maximum,minimum,and average growth rates of crust A1-1 (from the central Pacific) are 8.11,1.92 and 3.47 mm/Ma,and those of crust M1-1 (from the western Pacific) are 2.93,0.47,and 0.94 mm/Ma.

深盆气圈闭判识方法与应用

判识深盆气圈闭一般有3种方法：地质条件叠合法，理论模拟计算法，探测结果推定法。在深盆气勘探开发的不同阶段，由于研究的内容不同，对深盆气圈闭的判识采用的方法也不同。利用这3种方法识别深盆气圈闭，可以确定圈闭的分布和发育范围，同时认为，深盆气圈闭的形成存在一个地质门限，进入这一门限，深盆气才可在圈闭内聚集成藏。将实际资料分析与理论计算相结合，预测了鄂尔多斯深盆气圈闭的发育范围，可为该盆地深盆气的勘探与开发提供依据。

以α-Al2O3为载体，在加压条件下，采用初湿浸渍法制备了镧助Ni／α-Al2O3部分氧化-重整催化剂和负载型钙钛矿型LCFM／α-Al2O3燃烧催化剂，考察了反应温度、压力、CH4与氧配比等因素对两段法甲烷催化氧化制合成气性能的影响。结果表明，在两段法催化氧化制合成气工艺中采用LCFM／α-Al2O3燃烧催化剂和镧助Ni／α-Al2O3部分氧化／重整催化剂，能够消除反应热点，降低反应的危险性。当温度为1000℃及体系压力为2MPa时，甲烷转化率约为85％，CO和H2的选择性接近90％，与热力学平衡值十分接近；增加原料气中的氧含量，可以提高甲烷的转化率，但CO和H2选择性随之降低。
