随着近年来工程勘察和环境调查工作量的大幅增加,传统工勘钻机取心(样)质量很难满足实际需求,相比进口环境钻机采用多工艺手段取得的心(样)基本满足工程需求,但两种工艺方法体系缺少高效率、高质量、低成本的融合,对于实际施工作业造成突出的矛盾。本文以我国现行工程勘察标准、规范为出发点,分析XY-1、DPP100、GDC100、GDL-1等多款国产工程勘察装备与美国GP公司生产的多功能钻探装备,以及对比现行的工程勘察取心(样)多采用回转钻进,在复杂地层受到工艺方法和标准体系限制取心(样)质量相比国外发达国家开展的多工艺、多手段工程勘察明显存在差距。综合笔者的对比分析和实际研发工作,提出以开展多功能勘察装备的研发为前提,搭配多工艺取心钻具和工艺方法的配套性研究,结合数字化工程勘察理念,以实现精准勘察、高效勘察的目标。

Based on the full use of historical reservoir dispatching information, artificial intelligence is applied to grid reservoir group dispatching. A knowledge representation method, which combines dispatching rules and intelligence models, is put forward. The intelligent dispatching system is established and the system architecture is presented. Additionally, the acquisition, representation and reasoning mechanism of reservoir dispatching knowledge are designed in detail.

Although rare earth zirconates(RE_(2)Zr_(2)O_(7))have garnered attention as viable candidates for thermal barrier coatings(TBCs),they suffer from low fracture toughness and accelerated calcium–magnesium–alumina–silicate(CMAS)melt corrosion at high service temperatures,which impedes their practical *** this work,we developed a series of REAlO_(3)/RE_(2)Zr_(2)O_(7)(RE=La,Nd,Sm,Eu,Gd,and Dy)composites with a eutectic composition that not only significantly enhanced the fracture toughness by more than 40%relative to that of RE_(2)Zr_(2)O_(7)but also exhibited improved resistance to CMAS *** increase in toughness arises from multiple mechanisms,such as ferroelastic toughening,fine-grain strengthening,and residual stress toughening,all of which trigger more crack defects and energy ***,the CMAS penetration depth of the REAlO_(3)/RE_(2)Zr_(2)O_(7)composites is approximately 36%lower than that of RE_(2)Zr_(2)O_(7).Al–O constituents in composites can capture CaO,SiO_(2),and MgO in CMAS melts and increase their viscosity,resulting in enhanced CMAS corrosion *** thermophysical properties of the REAlO_(3)/RE_(2)Zr_(2)O_(7)composites were also investigated,and their coefficient of thermal expansion and thermal conductivity are comparable to those of 7–8 wt%Y_(2)O_(3)partially stabilized ZrO2(YSZ),indicating their potential as TBC materials.
