Method exploration of implicit logging geological information research

For a long time,the identification of geological phenomenon which was based on well logging information has the problem that well logging which is based on geophysical theory try to solve the geology and engineering question instead.Facing the complicated reservoirs,the well logging technology may have models transformation and connecting problem.The problem will cause structural contradiction of well logging evaluation.The contradiction which will produce unclear transformation relationship between well logs and their geological information causes most of geologic events that were recorded by well logging information in a hidden form or using a code record.For a long period,large amount of geological evidence which was hidden in well logging information lacks of effective identified theoretical basis.The identification of the recessive well logging geological information has become the critical technical problem in the development of well logging geology.The most efficient methods to study the recessive well logging geological information contain putting some particular well logging response or recognized boundary as a entry point,decoding the key information in well logging curves information though rock genesis mechanism,accumulation style and forming background et al,and doing some research about geological properties of well logging information though genetic relationship and difference compassion methods.The paper puts forward that these methods are identification principles and technical basis of well logging information and proprietary information and correspondent information of geological background.The paper further points out that the unity between macro and micro is the core methodology research of the recessive well logging geological information.Practice proves that well logging information has three important geological attributes.There are specialization,correspondence and the unity between the macro and micro.Former two are theoretical basis of identifying recessive well logging geological information.The latter one is an effective method of distinguishing true or false about identifying recessive well logging geological information.
