Abstract

Abstract:

Formation water from the second member of Xujiahe Formation, Xinchang structural belt, Sichuan Basin, is chemically complicated and highly variable in salinity, with some wells recording dynamic changes of chemical characteristics of produced waters.This paper discusses the migration of formation water based on a thorough analysis of the chemical characteristics of formation water from each interval of the Xujiahe Formation by using salinity data, chlorine/magnesiumionic ratios, metamorphism coefficients, Novák's phase diagrams and etc. The results show that the formation water of the second member has salinity values ranging between 70 and 110 g/L, chlorine/magnesium ionic ratios greater than 50 and metamorphic coefficients greater than 10; and that of the fourth member has salinity values ranging between 50 and 90 g/L, chlorine/magnesium ionic ratios less than 50 and metamorphism coefficients less than 10.Their Novak's phase diagrams also have obvious differences.These characteristics can be used to determine the stratigraphic origins of formation waters.The produced water from most wells in the second member show relatively stable chemical characteristics, indicating that the waters are sourced from the same stratigraphic interval. However, the produced water from some wells, such as Xin 856, Xin 2, Xin 10-1H and Xin 5, show significant variation of chemical characteristics. Judging by the graphs, the waters are multi-sourced. Alien waters of high salinity and high bromide ion concentration from marine Leikoupo Formation had been detected in wells Xin 2 and Xin 856 after Wenchuan Earthquake. Waters from the fourth member were also observed in wells Xin 10-1H and Xin 5.It is suggested that faults are the most likely pathways for this cross-layer migration of formation water.

Key words: chlorine/agnesium ratio, metamorphism coefficient, salinity, Novák's phase diagram, formation water dynamic change, Xujiahe Formation, Sichuan Basin
