| The oil field enters water flooding and develops in middle and later periods, it is unusually complicated that the oil well produces the state, form the salt, corrode, wear and tear, well influence that condition worsen day by day serious, especially document leave oil district release oil well knot salt issue that find seem particularly outstanding in the production management in Zhongyuan Oil Field in recent years. It belongs to typical high pressure , high temperature , high mineralization oil gas to hide that the document leaves the oil district, the oil well forms the salt seriously, has influenced the normal production of the oil well. Is it smoke oil pump , enter salt card oil valve shut off tight because of there is existence of salt crystallization to present often in actual production, cause the pump valve to seal losing efficiency etc.This text combines the actual conditions that Zhongyuan Oil Field recovers the oil at the scene at present, analyze systematically that influences the factor which is smoked the performance of the oil pump in forming the salt well, and propose the pertinence measure to the questions existed, in order to improve and smoke the serviceability of the oil pump in forming the salt oil well. This text explains at first that finishes the salt to smoke the well condition of the oil well and form salt mechanism, then analyzed the wearing and tearing of smoking the spare part of the oil pump serving in forming the condition of salt well , such basic invalid forms as corroding , machinery destroying (excessive and out of shape , ruptures ) and mechanical breakdown ,etc, these invalid forms have all influenced the performance of smoking oil pump in various degree. To smoking invalid many kinds of reasons in forming the salt well of the oil pump, from structure, select suitable materials, surface strengthen respect carry on discussion , is it is it release the performance measure in forming the salt well of the oil pump to improve to ask.For release oil pump form salt oil well use the condition form to offer a set of more comprehensive analysis materials this text, this helps to carry on further research to such respects as structure , selecting suitable materials , processing technology of smoking oil pump ,etc, help to improve the on-the-spot serviceability of smoking oil pump. To improving the output of crude oil of the oil field , reduce the homework expenses , reduce the production cost, the economic benefits of improving oil field development have important meanings. |
