本刊讯　胜利油田临盘采油厂工艺研究所成功地研制出一种多功能油井生产管柱。该管柱由特种深井泵、深井封隔器、多功能洗井阀等井下工具组合而成。它具有放大生产压差、避免油层污染、清蜡解堵、保护油层、防止油井倒灌、减少油井漏失等多种功能和优点。其显著的特点是施工简 The Journal Shengli Oilfield Linpan Oil Production Plant Technology Institute successfully developed a multi-functional production wells. The pipe string from the special deep well pump, deep packer, multi-function valve and other downhole tools combined. It has a variety of functions and advantages, such as enlargement of production pressure, avoidance of oil layer contamination, dewaxing of wax, protection of oil layer, prevention of oil well intrusion and leakage loss of oil well. The obvious feature is the construction of Jane
