現場應用測試表明： （ 1 ）耦合器傳動系統可改善抽油機啟動和傳動中的軟特性，提高整機和抽油桿的使用壽命； （ 2 ）解決了抽油機膠帶傳動中打滑「丟轉」和頻繁更換膠帶等問題； （ 3 ）實現了抽油機大傳動比，沖次任意可調，從而滿足供液不足油井和稠油注蒸汽生產井的不同需要； （ 4 ）可提高抽油機系統效率2 . 24 % ，日耗電量下降39 . 6 % 。The relationships among the rock permeability, water saturation and resistivity of weicheng oilfield in dongpu depression are studied by rock resistivity parameter testing and rock resistivity testing by water flooding. a comprehensive evaluation for water flooded reservoirs of 16 adjusting wells is carried out by using the testing results, by which the accuracy of interpretation is enhanced greatly
合理注采壓力系統是指既能滿足油田提高產液量的地層能量的需要，又不會造成原油儲量損失、降低開發效果的壓力系統.運用注采平衡的原理，對臨盤油田合理流動壓力、合理注水壓力和合理地層壓力進行系統研究，確定了該油田的合理的壓力系統，為今後油田開發提供了參考依據In view of its own international environment that daqing petroleum administration bureau faces in the overseas market development, with the guidance of transnational management theory and of strategic management theory, this essay analyses deeply and thoroughly its superiority an insufficiency, and the chance and threat it faces. the essay carries on considering and discussion on how to “ go out " and implement transnational management strategy for daqing petroleum administration bureau. finally, the essay puts forward the strategic mode which adapts to daqing petroleum administration bureau ’ s own characteristics and relevant problems and countermeasures that should be paid attention to while the strategy is made and implemented
本文針對大慶石油管理局海外市場開發面臨的自身環境和國際環境，以跨國經營的理論和戰略管理的理論作指導，深入分析其優勢與不足，以及面臨的機會與威脅，並對大慶石油管理局如何「走出去」 、實施海外市場開發戰略進行思考和探討，最終提出適合大慶石油管理局自身特點的海外市場開發戰略模式以及在海外市場開發戰略制定和實施過程中應該注意的相關問題及對策。The old control system mainly using - and - now ca n ' t meet the high and complicated requirements of modern ship to control its boiler. it is imperative under the situation to use computer for ship control area. and the remarkable plc used currently by industry process control area is the most reliable, simple and convention way to realize computer control on board modern ship. the paper introduce simply the basic principle of plc and the characteristic of simens plc s5 - 115u and a typical boiler system of huge oil tank. on this base, the paper pay more attention to making control programme of s5 - 115u for huge marine fuel oil boiler. and pid control method is singly adopted for water level control and steam pressure control of the fuel oil boiler
以繼電? ?接觸器為主的老一代控制系統已不能滿足現代船舶對其鍋爐控制的越來越高、越來越復雜的要求，這一領域的計算機化已勢由必行，而應用在當前工業過程式控制制領域中引入注目的可編程序控制器（ plc ）又是使其計算機化的最簡便和可靠途徑。本文主要介紹可編程序控制器（ plc ）的基本工作原理、德國西門子可編程序控制器s5 - 115u和大型油輪鍋爐的典型系統，在此基礎上對用西門子s5 - 115u控制大型船舶燃油鍋爐進行了編程。分享友人
