Identification of The Ground Water Surface With Log Data

Because of the deeper phreatic water surface caused by dry air in some regions of Caidamu basin and looser stratum in the upper part,very distinct reservoir characters could be found on logs.But there aren't any fluid out in oil-testing.Thus this kind of reservoir would be misunderstood as an effective one without knowing the characters.Furthermore,the water surface is different in different structures,even in the same structure there would be difference because of the fault isolation.A set of approach to determining the water surface is worked out with logs affer analysing large quantity of logs and oil-testing information.It is proved this approach is effective in actual practice.
