It was established that the structural and geothermal conditions of the upper Precambrian–Paleozoic sections are similar to those in the western regions of the Siberian platform and are characterized by rather low geothermal gradients(12.5–25.5 ℃/km). In the western parts of the basin, formation temperatures in the uppermost pre-Jurassic sediments are 50℃–85℃, decreasing eastward to 30℃–55℃. For the first time, the detailed geothermal model of the basin sedimentary fill was developed. This model allows predictions of the geothermal conditions of Earth’s interior.展开更多

An erupting-flow model, which is adaptable to the steaming and erupting of flow from wells in the field, has been verified by actual cases.展开更多
