生产测井是指在油气井或注水井投产后进行的一系列井下测量工作,其目的是想得到井内各种流体的性质和流动状况的资料.与常规测井的区别是,生产测并是在油井动态情况下进行的,用于确定储集层的动态和井存在的问题,以便为油井管理和采取增产措施提供依据.常规的动态管理是以地面计量和井下压力为依据,但对于多层和厚层油藏,上述资料很不完善,而生产测井则可以指出井内每个点产出或注入的流体的性质和数量. Production logging refers to a series of downhole surveys conducted after the production of oil and gas wells or injection wells and aims to obtain information on the nature and flow conditions of various fluids in the well.The difference with conventional logging is that production is measured at Well dynamics are used to determine reservoir dynamics and well problems to provide a basis for well management and stimulation measures. Conventional dynamic management is based on surface measurements and downhole pressures but for multi-layer And thick reservoirs, the above information is poor, and production logs indicate the nature and amount of fluid produced or injected at each point in the well.
