声波变密度测井干扰对油区固井评价影响分析

Analysis on acoustic variable density logging interferences for well-cementating evaluation in oil region

针对油区声波变密度测井中出现的干扰问题,例如在声波变密度测井成果图上有短横线干扰,结合水泥胶结组合仪测井原理,分析了声波变密度测井中形成干扰的因素及其对固井评价的影响,提出对各种干扰的判断和解决方法。

Aiming at some occurrent interfering problems during acoustic variable density logging in oil region,for example,some short horizontal linear interference has appeared in the acoustic variable density logging drawing,and combining with the logging principles of cement bond composed logging tools,this paper has analyzed the factors of forming interferences during acoustic variable density logging and the influences for well cementing evaluation,and suggested some methods to judge and solve every interference.
