深部油气资源的勘探与开发已成为当今解决石油资源短缺的一个重要途径。多极子阵列声波测井仪(MPAL)是新一代声波测井仪器。但目前国内多极子阵列声波测井仪一般只能用到150℃左右的环境温度,远远不能满足深部(大于5000米)油气勘探的需要。多年来,高温高稳定压电陶瓷材料难以取得实质性突破一直是制约我国高端声波测井仪器发展的主要技术瓶颈。中国科学院上海硅酸盐研究所针对锆钛酸铅〔Pb(Zr1-x Ti x)O3,PZT〕和偏铌酸铅(Pb Nb2O6)两类压电陶瓷在高温应用中急需突破的技术难题,开展了压电陶瓷组成设计新方法研究和制备技术创新研究,经过多年的持续攻关,成功研制出了具有完全自主知识产权的高温高稳定PZT和Pb Nb2O6压电陶瓷,满足了声波测井仪器深部油气勘探的需求,并取得了一系列创新性成果,推动了我国声波测井的技术进步。
The exploration and exploitation of deep oil and gas resources have become an important way to solve the shortage of oil resources today. Multipole Array Acoustic Logging Tool (MPAL) is a new generation of acoustic logging tools. However, at present, the domestic multi-polar array acoustic logging instrument can only generally use an ambient temperature of about 150 ° C., which far can not meet the needs of deep (greater than 5,000 meters) oil and gas exploration. Over the years, it has been difficult to make substantial breakthroughs in high temperature and high stability of piezoelectric ceramic materials has been the main technical bottleneck restricting the development of China’s high-end acoustic logging tools. Chinese Academy of Sciences, Shanghai Institute of Ceramics Targeted at the technical problems that two types of piezoelectric ceramics, PbTiOx [Pb1 (Zr1-xTix) O3, PZT] and PbNbO3, Launched a new method of piezoelectric ceramic composition design and preparation of technological innovation research, after many years of continuous research successfully developed with independent intellectual property rights of high temperature and stability of PZT and Pb Nb2O6 piezoelectric ceramics, to meet the deep acoustic logging tools The demand for oil and gas exploration, and made a series of innovative achievements, promote the technological progress of sonic logging in our country.
