Patent analysis for the acoustic logging while drilling technology. Pl, 2010, 24(4): 1-3 Based on patent data statistics, the writer analys es trends in acoustic logging-while drilling(lw d) technology, and introduces pat ents approaches used to cancel or suppress interferen ces such as collar arriv als and drilling noise signals Key words: acoustic logging while- drilling (lW D); patent statistics; trend analysis Li Lipin, Huang Yangun and Luo Bingwu. Design and realization of a temperature monitoring and displaying system based on DSP. Pl, 2010, 24(4): 4-6 A Lemperature monitoring and d isplaying systen based on DSP is designed. a digital temp erature sensor DS 18B20 is used to collect temperature. And a kind of TM 320240EFGW liquid crystal display module is used for real-t ime dis play. An Universal Serial RS232 interface is used to communicate with a PC. Therefore, this system has many adv ar tages such as sample circuIt, low power consumption, easy realtime data transmssion, and so on Key words temperature mon itoring; liquid crystal display; Digital Signal Processor Wang JunQi. Application and design of the well head isolation tool shifts alarm device for wireline log. Pl 2010,24(4):7~9 In view of the project ac cident caused by the well head isolat ion tools accidental shift of the wireline log construct ion in the process of the oilgas field explorat ion and development, the auto alarm inst aliment is designer if the position of the well head isolation tool is changed. This article introduces in detail the principle of work, the production process and the application method of the alarm device. and it further confirms the equ ipment s security and the usability through the practical application Key words: wireline log; well head isolation tool; alam; shifting Sun renyuan, Zhan Yongping, li Aifen, Zhang Y uanfa and Zhang huben. Design and property tests of the PVT analy zer of formation oils. Pl, 2010, 24(4: 10-12 The PVT analyzer of formation oils can be used to measure the bubble point, solution gas oil ratio and format ion volume factor of formation oils under reservoir temperature and pressure. It is one of the basic equipments for oil and gas field development. A set of new PVT analyzer was designed for the use of experimental teach ing and scient ific research es. The inst allation and property tests were conducted Experiments show that the Pvt analy zer can be used for PVt pa rameter neasurement of formation oils under fornation Len perature and pressure. The measuring results are precise and repeatable. It is easy to use and can meet the needs of st udents teaching and scientific res arches Key words: formation oil; PVT analyzer; property test Wang Wenzheng. The analysis on two kinds of hydrophone positioning technique. Pl, 2010, 24(4): 13-14, 16 The paper first introduces one method to realize hydrophone positioning. Then two kinds of systems of hydrophone posit ioning principle are explained. The function of every part is des cribed in detail. At last the paper gives a conclus ion based on the contrast of them Key words position ing; hy drophone; sonar; tronspon der He Xiaozhen. structure design impro vement of the signal pro be alignment in litholo gy density logging tool. Pl, 2010,24(4):15-16 In this article the problem of probe alignment disconnect ion of lithology density logging tool was investigated, and the crux of the issue was identified. Based on the ongoing improvement of local spatial structure design, the space w as extended th is improv ement both ensures the reliability of the equipment and improves the customer s atisfaction This work is also instructive for other instrument design Key words: caliper assembly; caliper potentiometer; lead arm; alignment; SPace Shao Fang, Guo Qingfeng, Ii liang, Hou Chunhui and Yang Xiao. The design of transmitted circuit of sector cement bond tool Pl, 2010, 24(4): 17-18 a kind of transm itted circuit of sector cement bond tool has been des igned. This paper genera lizes the theory of the sector cement bond tool and the design approach of the transmitted circuit, and elaborates the work ing principle of the tool. The circuit reduces the number of components and saves space through optimization design Key words: sector cement bond piezoelectric crystalp transmitted circuita time sharing transmitting/www cnkinet
