Abstract


Przedstawiono skład gazowy wód poziomów zbiornikowych dewonu i karbonu obszaru lubelskiego. Skład chemiczny tych gazów jest jednym z najpewniejszych wskaźników przy poszukiwaniach węglowodorów. Na podstawie przeważającego składnika gazowego, budowy geologicznej oraz warunków hydrogeologicznych i hydrodynamicznych wydzielono szereg stref perspektywicznych dla poszukiwań nagromadzeń węglowodorów.

GASES DISSOLVED IN WATER OF DEVONIAN AND CARBONIFEROUS ROCKS IN THE LUBUN AREA

The chemical composition cl gases dissolved in water of Devonian and Carboniferous aquifers of the Lublin area are discussed as one of hydrochemica1 criteria for determining oil- and gas- bearing potential.

The groups of indirect and direct local hydrochemical indices a perspectiveness are discussed. The study is mainly based on laboratory analyses a composition a gases In water samples obtained from sampling a deep drillings a the Geological Institute. Table 1 gives chemical composition of gases dissolved in water from Devonian and Carboniferous aquifers in the Lublin region in per cents. The changes in composition of gases in water in the vertical section a the studied stratigraphic units and throughout the area a distribution of these rocks are discussed in detail (Fig. 3, 4).

The chemical analysis of gases dissolved in water of the Devonian ·and Carboniferous aquifers and comparison of the obtained data and general features of geological structure of the Lublin area and its hydrogeological and hydrodynamic conditions made it possible to delineate several zones which may represent perspective objects for search of hydrocarbon accumulations (Fig. 1,
