| The study of Cambrian intersalt levels in the Angara-Lena petroleum region is currently of great importance. These strata are considered, on the one hand, as a return target for gas exploration, and on the other, as the main source of hydromineral raw materials. Under these circumstances, analysis of well testing data and well geological complications in the Angara-Lena petroleum region are necessary for understanding the fundamental patterns of the geological structure of Cambrian intersalt levels. Testing and various well complications were analyzed for over 400 wells. It is shown that the Osinsk level has been the most extensively tested. The maximum number of brine shows was observed during drilling in the Usol Formation, while the largest number of gas shows were recorded in the Angara Formation. The upper part of the Cambrian salt bearing structure (the Litvintsev Formation and Angara Formation) is characterized by intense mud losses. The results of these studies can be used in planning geological exploration in the Angara-Lena petroleum region of Eastern Siberia. Keywords: intersalt level, Cambrian, well testing data, well geological complication, Angara-Lena petroleum region, Eastern Siberia. |
