Objective：By the healthy survey of drinking water of a oilfield, we can realize the sanitary condition, and provide the initial value of drinking water quality monitoring, and provide the basis for improving the quality of drinking water, Methods ： In the light of （ GB/T5750 - 2006） ＂Standard testing meth- ods for drinking water＂, a survey of initial value of drinking water of the 52 Selfsupply well was carried out. , we collected water samples from the wells, and detected them in 30 primary indicators. Results：In the detecting results of the 30 indicators of 52 wells, only one qualified and the pass rate is 1.9%, the over - limit ratio of Total coliform is 94.2%, the heat - resistant 65.4%, the Escherichia coli 59.6% , and the total plate count 59.6%. Mercury, lead, iron, and manganese are over proof in various degree, respectively by 17.31%, 15.38 % ,7.69% and 7.69 %. Conclusion：Bacteriological indicators are the major factors threatening the quality of the drinking water, so the health protection of water source and the management of Drinking water disinfection should be strengthened.
