xxxx石油仪器有限公司位于涿州市开发区，是专业生产地震检波器、电缆及地震仪器配件的科技公司。公司主要技术人员均有在石油物探行业工作的经历，也包括石油行业公认的地震检波器研究专家，具有20多年的研究历史。
本公司科技人员在致力于检波器的开发与研究的同时，还与天津大学、天津科技大学等多所院校合作，开发出多种适应于新的地震勘探需要的产品，公开发表相关学术论文多篇，获得国家发明、使用新型专利13项，20DX超级检波器和加速度检波器都是具备自主产权的产品。公司投资5000万元建设的厂区，占地50余亩，建筑面积一万六千平方米，公司现有员工239名，其中科研人员36名。
随着地震勘探技术的不断提高，高分辨率勘探已成为地球物理专家们的首选课题。石油仪器的动态范围已达到120dB以上，但接受第一手资料的设备—地震检波器的动态范围只有60dB，明显成为高分辨率地震勘探的瓶颈。
本公司科研人员致力于检波器研究十几年，紧随地震勘探的步伐，吸取各类检波器之优势，推出新一代加速度检波器CD—JSII。该产品动态范围75dB；接受频率1—300Hz；灵敏度随频率的增加而增加；阻尼数大于1；该产品无须外部供电。内部结构采取了特殊工艺，使用寿命有了进一步的提高。CD—JSII检波器经中国计量科学院进行技术鉴定，认为在不同频段灵敏度都很高，是一种理想的检波器。通过大庆油田、华北油田、四川油田、、煤田地质局、大平煤矿的施工受到使用单位的高度评价。认为：CD—JSII检波器动态范围大、接收频带宽、灵敏度高，有利于接受薄层、深层弱信号，不仅适应于高分辨率勘探，同样应于常规地震勘探。
Zhuozhou Challenger Geoinstruments Co., Ltd., located in Zhuozhou Development Zone, is a scientific Company with a history of 20 years of research, specialized in the production of seismic geophone, cable and seismic apparatus and accessories. All the key technical personnel in the Company have the working experience in the petroleum exploration industry, including the industry-recognized experts in geophone research.
The scientific and technical personnel of the Company are committed to the development and research of seismic detectors, at the same time, cooperate with a number of academic institutions, such asTianjinUniversityand Tianjin University of Science and Technology, and have developed a variety of products that meet the new demand of seismic exploration. The Company has published many relevant academic papers, and obtained 13 national inventions and utility model patents. The 20DX super geophone and acceleration geophone are the products with independent property rights. The plant of the Company, which has been invested 50 million Yuan in construction, covers an area of 50 acres, with a construction area of 16,000 square meters. The Company owns 239 employees now, including 36 researchers.
With the continuous improvement of seismic exploration technology, high-resolution exploration has become the preferred subject for geophysical experts. The dynamic range of petroleum instruments has reached over 120dB, but the equipment receiving the first-hand information – geophone only has the dynamic range of 60dB, which has obviously become the bottleneck of high-resolution seismic exploration.
Following the pace of seismic exploration closely, the researchers of the Company has been committed to geophone research for more than a decade, and has unveiled its next generation of acceleration geophone - CD-JSII which has absorbed the advantages of various types of seismic detectors. The dynamic range of the product reaches 75dB, received frequency 1-300Hz, and the damping number is larger than 1, and its sensitivity increases with the increase of frequency. This product eliminates the need for an external power supply. Its internal structure adopts special processes, which has further improved the working life. The CD-JSII was appraised to be an ideal seismic detector with very high sensitivity in different frequency bands by the National Institute of Metrology. The product was highly evaluated by a number of units in construction, such as Daqing Oilfield,Huabei Oilfield,SichuanOilfield, Coalfield Geology Bureau, Daping Coal Mine, etc. They think that the large dynamic range, wide frequency acceptance band and high sensitivity of CD-JSII detector is conducive to receive weak signals at thin and deep layers, which not only adapts to the high-resolution exploration, but also can be used in the conventional seismic exploration.
