Własności zbiornikowe utworów mezozoicznych niecki warszawskiej w świetle badań geofizyki wiertniczej
Abstract
Przedstawiono metodykę obliczenia parametrów zbiornikowych skał (porowatości, zailenia i nasycenia wodą) na podstawie badań geofizycznych. Uzyskane wyniki opisano syntetycznie za pomocą średnich wartości tych parametrów dla poszczególnych poziomów stratygraficznych oraz map porowatości i zailenia, na podstawie których przeprowadzono analizę własności zbiornikowych skał na obszarze niecki warszawskiej. RESERVOIR PROPERTIES OF MESOZOIC ROCKS IN THE WARSAW BASIN IN THE LIGHT OF WELL LOG DATASeveral layers with good reservoir properties have been found in the Bundsandstein, Rhaetian, Keuper, Lower, Middle and Upper Jurassic (especially Oxfordian) and Lower Cretaceous in the Warsaw Basin. Reservoir properties of these layers are here characterized with reference to mean values of the following parameters: coefficient of porosity, established on the basis of results of bore hole electrometry (KpR) and neutron profilling (KpN) and coefficients of clay content (Ci) and saturation with water (Kw).Tables 1–6 show these values. Moreover, porosity and clay content maps drawn for individual stratigraphic units are also shown (Figs. 2, 4–7). The paper primarily deals with interpretation of the above mentioned well log data. Some comments on methods of evaluating the reservoir parameters are also made.Downloads
