| Main results of regional seismic exploration activity in southern part of Vilyuy Syneclise, Republic of Sakha (Yakutia) | |
| The regional seismic exploration carried out in the southern part of the Vilyuy hemisyneclise made it possible to The regional seismic exploration carried out in the southern part of the Vilyuy hemisyneclise made it possible to obtain new data and to improved the information on the geological structure of the territory, to recognice promising objects for oil and gas, including a large, gas-promising dynamic anomaly and significant areas of reduction in the thickness of the Upper Paleozoic and Lower Mesozoic strata, where the formation of traps associated with pinch-out and lithological replacements is quite likely. On this basis, the prospects for the oil and gas content of the studied area have been significantly expanded. In addition, in its eastern part (Sinsk area), the position of the West Yakutsk reef barrier has been clarified and the horst-like structures have been identified along the lower levels of the sedimentary cover. The directions of further exploration activity, including the drilling of parametric wells, are proposed. The presentation of geological results is accompanied by an analysis of the scientific issues of seismic exploration in the southern part of the Vilyuy Syneclise. It is shown that in conditions of poor geological and geophysical knowledge, the significance of the results of regional seismic exploration in the study of the structure and prospects of oil and gas content increases many times. It seems extremely important to sound and careful planning of such studies in the studied region. Keywords: oil and gas content, seismic exploration activity, oil and gas promising objects, Eastern Siberia, Vilyuy Syneclise. |
