Abstract: There are plenty of petroleum geology implications in geochemical fields of oil field water systems. It is very important for studying the geochemical fields to guide exploration and development of petroleum. Oil field waters of Eogene System in Huanxilin Shuangtaizi area, the Western Depression, Liaohe basin, can be divided into six oil field water systems. The oil field water systems are:(1) the oil field water system of No.4 Section of Shahejie Formation, (2)the oil field water system of lower No.3 Section of Shahejie Formation, (3)the oil field water system of middle upper No.3 Section of Shahejie Formation, (4)the oil field water system of No.2 Section of Shahejie Formation, (5)the oil field water system of No.1 Section of Shahejie Formation, (6)the oil field water system of Dongying Formation. Though the types of all oil field water of the six systems in Huanxilin Shuangtaizi area, Western Depression, Liaohe basin are the low mineralized bicarbonate sodium, it is very different among mineralization intensity fields and reduction factor fields in the six oil field water systems. The differences are not only the different abnormal areas of the geochemical fields in the six oil field water systems, but the different locations of abnormal areas of the geochemical fields among the six oil field water systems also. The abnormal areas are represented their petroleum geology implications in the six oil field water systems respectively. Generally, the positive abnormal areas of mineralization intensity and the negative abnormal areas of reduction factor in oil field water system have the advantage of petroleum to be accumulated and reserved. The geochemical fields of oil field water systems of Eogene System in Huanxilin Shuangtaizi area, Western Depression, Liaohe basin don't show the consistent of the conditions of petroleum accumulation and reservation in the sections and formation of Eogene System in the study area.
