黄骅坳陷风化店地区火成岩研究与识别

黄骅坳陷风化店地区已开发的砂岩油层组已进入开发中后期，寻找新的潜力油气藏迫在眉睫．相邻区块辉绿岩油气藏的发现，使风化店地区火成岩油气藏得到关注。该地区火成岩油气藏规模较小，有利目标区难以明确，针对这一问题，从火成岩及其蚀变带的分布入手，在详细分析录井显示的基础上，对火成岩储集层电性、岩性及物性特征进行了评价，通过研究火成岩侵入带与孔二段油气藏的关系，发现Z111断块高部位井区可作为油气开发的有利目标区．明确了该地区进一步勘探的方向。

Thick Graded Nanostructured Zirconia-NiCoCrAlY Composite Coatings by Plasma Spraying

Thick Nanostructured PSZ-NiCoCrAlY graded TBCs were got byair plasma spraying. The results reveal the morphology and phase transformation of TBCs by means of SEM and XRD. The plasma spray process results in a characteristic layered structure consisting of lamellae, unmelted nano-particles and an inter-lamellar porosity. The test results of thermal shock show that the graded coatings have different failure behavior. The failure mode was the spallation of top coat due to thermal stress. It has been found that the lamella consists of nanoscale columnar grains parallel to the spraying direction.

KEY TECHNIQUES IN R&D OF OUT-SIZE EXTRUSION PRESS WITH OIL-DRIVEN DOUBLE ACTION

A modern design method, in which traditional design formulas are conjoined with numerical simulation and optimization, is successfully used to design the out-size extrusion frame precisely so that the press cost can be saved. A new technology used for decompressing by a multi-steps dynamical mode is put forward, which makes it possible to decompress the large flow-volume high-pressure oil in the main cylinders. In addition, a method for realizing the fixed mandrel process by hydraulic support is proposed and its control equation is established. Pre-tightening frame tests are carried out by over-operating pressure on 100 MN aluminium extrusion press with oil-driven double action, which is developed based on the above key techniques and is the largest press so far in the world, and the results show that the frame structure designed is reasonable and reliable, and the modem design method used is an useful tool for designing large and out-size heavy plastic forming machinery. The results of decompressing curve in main cylinder and noise inspection indicate that multi-steps dynamical mode for decompressing the large flow-volume high pressure oil is valid and reliable. Meanwhile, the fixed mandrel process is well realized based on the control equation. These key techniques have been used in the development of 125 MN aluminium extrusion press with oil-driven double action.     

Using Fractional-order Piλ Dμ Controller for Control of Aerodynamic Missile

A new type of PID controller is introduced and some properties are given. The novelty of the proposed controller consists in the extension of derivation and integration order from integer to non-integer order. The PIλDμ controller generally has three advantages when compared to the integerl-order controller: the first is that it has more degrees of freedom in the model; the second is that it has a memory in model, the memory insure the history and its impact to present and future, the third is it ensures the stability of missile. This approach provides a more flexible tuning strategy and therefore an easier achieving of control requirements. Flight dynamic model of an aerodynamic missile is taken into account in implementing the PIλDμ controller. Simulation results show that the PIλDμ controller is not sensitive to the changes of control parameters and the system parameters. Also, the controller has more flexible structure and stronger robustness.
