xxxx石油儀器有限公司位于涿州市開發(fā)區(qū)，是專業(yè)生產(chǎn)地震檢波器、電纜及地震儀器配件的科技公司。公司主要技術(shù)人員均有在石油物探行業(yè)工作的經(jīng)歷，也包括石油行業(yè)公認(rèn)的地震檢波器研究專家，具有20多年的研究歷史。
    
    本公司科技人員在致力于檢波器的開發(fā)與研究的同時，還與天津大學(xué)、天津科技大學(xué)等多所院校合作，開發(fā)出多種適應(yīng)于新的地震勘探需要的產(chǎn)品，公開發(fā)表相關(guān)學(xué)術(shù)論文多篇，獲得國家發(fā)明、使用新型專利13項，20DX超級檢波器和加速度檢波器都是具備自主產(chǎn)權(quán)的產(chǎn)品。公司投資5000萬元建設(shè)的廠區(qū)，占地50余畝，建筑面積一萬六千平方米，公司現(xiàn)有員工239名，其中科研人員36名。

隨著地震勘探技術(shù)的不斷提高，高分辨率勘探已成為地球物理專家們的首選課題。石油儀器的動態(tài)范圍已達(dá)到120dB以上，但接受第一手資料的設(shè)備—地震檢波器的動態(tài)范圍只有60dB，明顯成為高分辨率地震勘探的瓶頸。

         
  本公司科研人員致力于檢波器研究十幾年，緊隨地震勘探的步伐，吸取各類檢波器之優(yōu)勢，推出新一代加速度檢波器CD—JSII。該產(chǎn)品動態(tài)范圍75dB；接受頻率1—300Hz；靈敏度隨頻率的增加而增加；阻尼數(shù)大于1；該產(chǎn)品無須外部供電。內(nèi)部結(jié)構(gòu)采取了特殊工藝，使用壽命有了進(jìn)一步的提高。CD—JSII檢波器經(jīng)中國計量科學(xué)院進(jìn)行技術(shù)鑒定，認(rèn)為在不同頻段靈敏度都很高，是一種理想的檢波器。通過大慶油田、華北油田、四川油田、、煤田地質(zhì)局、大平煤礦的施工受到使用單位的高度評價。認(rèn)為：CD—JSII檢波器動態(tài)范圍大、接收頻帶寬、靈敏度高，有利于接受薄層、深層弱信號，不僅適應(yīng)于高分辨率勘探，同樣應(yīng)于常規(guī)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.
