准噶尔盆地腹部超压层分布研究

准噶尔盆地腹部普遍发育深层（大于4000m）超压系统，很多钻井都钻遇超压。通过对超压段钻井、地质、测井、地震特征系统研究发现，超压段泥浆密度大幅增加，具有高声波时差、低电阻率以及地震低速的超压响应特征。利用Dix公式计算地震层速度和利用Fillippone公式计算地层压力，得到超压数据体。准噶尔盆地腹部超压在白垩系及其以下沉积地层中均有分布，超压层的深度范围不同。分1井西凹陷边缘以及昌吉凹陷西南有空层现象。超压顶面分布的层位由北往南、从东到西逐渐变浅，从三叠系顶部到白垩系底部。深部超压对油气分布和富集有着重要的控制作用，准噶尔盆地腹部超压层分布的研究将对本区油气勘探起积极的推动作用。     

MPLS技术在全球范围内的争议

MPLS技术兼具了IP技术的灵活性和ATM技术交换速度快、有QoS保证、流量控制等诸多优点,可以解决网络中存在的拥塞、QoS、VPN支持和组播等方面的一系列问题,是一种新兴的IP骨干网技术。但经过几年的实践,人们对它的能力提出怀疑出现了争论。从MPLS这几年的发展历程看,MPLS是目前最有希望的下一代骨干网技术之一,但它并不象原来设想的那样,可以解决网络中存在的所有问题。

Positive interpolation with rational quadratic splines

A necessary and sufficient criterion is presented under which the property of positivity carry over from the data set to rational quadratic spline interpolants. The criterion can always be satisfied if the occuring parameters are properly chosen.     

Determination of instantaneous corrosion rates and runoff rates of copper from naturally patinated copper during continuous rain events

Instantaneous corrosion rates of naturally patinated copper of varying age (16 months, 138 and 145 years) have been determined during continuous rain events in the laboratory with electrochemical impedance spectroscopy using a two-electrode cell. The two-electrode cell was found to yield the same information in bulk rainwater as a conventional three-electrode cell.Relatively constant corrosion rates, between 0.2 and 0.6 μm/y, were determined for samples having a two-layer structure with an inner brownish layer of cuprous oxide and an outer greenish layer of basic copper salts (138, 145 years). Samples with cuprous oxide as the dominating phase of the patina (16 months) showed higher and somewhat increasing corrosion rates during a rain event (from 0.6 to 1.2 μm/y). During a continuous rain event, corrosion rates were found to be approximately 10 (brownish patina) and 25 times (greenish patina) lower than corresponding instantaneous runoff rates. The first flush phenomena of the runoff process, with an increased concentration during first flush and a relatively constant concentration during steady state, was indirectly seen as an increase in solution conductivity during the first rain volume followed by relative constant value. The contribution of the concentration in the first flush to the total annual runoff rate was significant for panels having a greenish layer (138, 145 years) whereas it was negligible for panels having a brownish layer (16 months).     

改进的第三代相干算法及应用

在讨论相干技术发展及三代相干算法优缺点的基础上，介绍了改进的第三代相干算法。应用自行开发的相干软件对多个油气勘探和开发区块的三维地震资料进行处理、分析，对相干时窗长度、相关道数等参数对算法效果的影响及相干体对断层、异常地质体的识别，以及解释方法进行了探讨。应用实例证明，改进的第三代相干算法抗干扰能力强，横向分辨率高，不仅适用于倾斜地层，而且对断层尤其对小断层、异常地质体具有较高的检测能力，是油气勘探和开发的一项有效和实用的技术。
