本文系统剖析了鄂尔多斯中部气田下古生界水化学特征及与天然气藏的关系 ,初步提出了天然气藏富集区 (或含气区 )的水化学综合判识指标。鄂尔多斯中部气田下古生界地层水以偏酸性为主 ,具有总矿化度高、Cl-和Ca2 + 离子占优势、有机酸和烷基酚含量高的特征 ,反映出下古生界地层水处于阻滞—停滞的水文地质状态 ,有利于天然气的聚集与保存。研究认为 ,水化学组成与天然气藏有密切的关系 ,总矿化度高值区 (>15 0 g/l)、CaCl2型水分布区、rNa/rCl低值区 (≤ 0 3.、rCl/rMg高值区 (>15 )、rMg/rCa低值区 (≤ 0 2 )、有机酸含量高值区 (>40mg/l)和酚含量高值区 (>2 0mg/l) ,将是天然气藏富集的有利区。因此 ,利用水化学和地质地球化学相结合的综合研究 ,可为天然气藏富集区 (或含气区 )的找寻和预测提供依据。

特低渗透断块油藏的几何形状以及流体非线性渗流特征都对井网部署有影响。针对不同几何形状的特低渗透断块油藏设计了不同形式的注采井网,以江苏油田花17断块为例,在考虑流体非线性渗流特征的前提下,应用研发的非线性渗流数值模拟软件对每种井网形式进行了开发效果评价。研究表明,对于可以部署两排直井的条带状断块油藏,注水井"隔一布一"地正对采油井部署的方式相对最优;小型条带状油藏选择水平井采油直井注水时,注水井的相对最优位置为水平井井趾的外围;对于可以部署少量直井的小三角形油藏,注水井置于采油井排外侧有利于提高开发效果。此项研究为特低渗透断块油藏的井网优化提供了一种新方法。

柴达木盆地在一定深度及区域上普遍存在异常高压。一方面 ,异常高压是油气运聚的一种重要动力来源 ;另一方面 ,异常高压在一定地质背景下是控制油气分布的重要因素。在油气运移中 ,可以使上覆封隔层产生大量微裂缝 ,油气向上运移到在较低压储集层中 ,也可以使封闭性断层开启 ,通过断层进行侧向运移 ;异常高压形成的流体势能驱动流体从凹陷中心向凹陷边缘流动 ,最终形成油气藏围绕生油凹陷分布的格局。该区与异常压力有关的油气成藏模式可以概括为 3.类型 ,即 :位于异常高压体系内部裂缝型高压油气藏 ,异常高压体系下部孔隙型高压油气藏 ,位于封隔层之上的孔隙型常压油气藏。

Marine carbonate oil and gas fields have become an important exploration area in china and even across the world. Their formation, distribution and enrichment are special owing to the complexity of the deposition, diagenesis and accumulation, which is caused by the multiplicity of the carbonate depositional environments and facies, huge extensions of formation time and burial depth, complication of diagenetic evolution, heterogeneity as well as the development of pores, caves and fractures affected by various factors. Oil and gas accumulations in carbonate rocks are not strictly controlled by the second-order structure belt. Most of them, under certain structural settings, are controlled by sedimentary diagenesis and its favorable facies. The hydrocarbon reservoir type is predominantly stratigraphic. Based on the worldwide researches of carbonate fields, the paper concludes that 7 main factors control the formation and distribution of middle-large marine carbonate stratigraphic fields.

In order to predict favorable exploration areas of the Paleozoic, Carboniferous and Silurian clastic reservoirs in the Tazhong area of the Tarim Basin, west china, we studied the basic characteristics of Paleozoic clastic reservoirs in the Tazhong area based on a lot of data. Several issues about the hydrocarbon accumulation related to the reservoirs were also discussed. The results were concluded that： the high-value areas of the porosity and permeability of clastic reservoirs were located in the southeast of the Tazhong area; the content of cement （carbonate cement in particular） was the main factor controlling the porosity and permeability of clastic reservoirs; the hydrocarbon distributions of Carboniferous and Silurian clastic reservoirs were closely related to the porosity and permeability; the favorable hydrocarbon accumulation areas of the two sets of strata were located in the southeast of this area, especially in the updip pinch-out area.

High-quality SrRuO3.(SRO) thin films and SrTiO3.SRO bilayer were grown epitaxially on SrTiO3.(STO)(001) substrates by laser molecular beam epitaxy. The results of in situ observation of reflection high-energy electron diffraction and ex situ X-ray diffraction θ -2θ scan indicate that the SRO thin films have good crystallinity. The measurements of atomic force microscopy and scan tunneling microscopy reveal that the surface of the SRO thin film is atomically smooth. The resistivity of the SRO thin film is 3.0 μΩ·cm at room temperature. Furthermore, the transmission electron microscopy study shows that the interfaces of STO/SRO and SRO/STO are very clear and no interfacial reaction layer was observed. The experimental results show that the SRO thin film is an excellent electrode material for devices based on perovskite oxide materials.

研究了煤层气储量计算方法 ,研究表明 ,煤层气储量计算中最重要的参数是含气量。影响含气量的主要因素包括盖层分布、地层压力及水动力条件等 ,含气量的分布随上述条件的变化而有所不同。煤层气的储量计算要考虑到煤层气的特殊性 ,同时参照流体矿藏 (天然气 )和固体矿藏 (煤炭 )储量计算方法。煤层气藏的储量计算不同于常规天然气 ,其含气边界的确定是以煤层含气量等值线确定的。圈定含气面积的最低含气量值根据煤层气藏地质条件、采用煤层储量历史模拟软件进行模拟确定 ,并参考国外煤层气开发选区的含气量标准煤层气储量计算方法有体积法和数值模拟法。数值模拟方法适合开发中期或者是生产试采资料很丰富的情况下使用。通过沁水煤层气田储量的计算验证了计算方法的可行性。

This paper aims to provide further study on the nonlinear modeling and controller design of formation flying spacecraft in deep space missions. First, in the Sun-Earth system, the nonlinear formation dynamics for the circular restricted three-body problem （CRTBP） and elliptic restricted three-body problem （ERTBP） are presented. Then, with the Floquet mode method, an impulsive controller is developed to keep the Chief on the desired Halo orbit. Finally, a nonlinear adaptive control scheme based on Nonzero set- point LQR and neural network is proposed to achieve high precision formation maneuver and keeping. The simulation results indicate that the proposed nonlinear control strategy is reasonable as it considers not only the orbit keeping of the Chief, but also the formation modeling inaccuracy. Moreover, the nonlinear adaptive control scheme is effective to improve the control accuracy of the formation keeping.
