The article shows the need for create geotechnologies adapted to continuous natural changes in the geological environment. To solve this problem, data are required on transit thalwegs, indicators of the prevailing process of matter increasing compaction to the Earth center, on the character planet rotation around its axis and movement along its orbit. Systems of transit thalwegs have been identified in the considered area of the Okhotsk Sea oil and gas province. Taking them into account, the boundaries of the transit thalwegs nodes spheres (structures natural control of different ranks denudation processes) were determined. The features of the negative processes development (earthquakes, flood zones, etc.) have been established taking into account the identified structures and the rotation factor. As studies have shown, it is advisable to consider all (including negative) geological processes within the framework of structures natural control of different ranks denudation processes. In this case, it becomes possible to identify their patterns and use these data to develop new effective geotechnologies. Since the first level of hydro- and lithodynamic flows natural control is realized in the node thalwegs (one is transit, the other is an active inflow to it), each sphere has a certain degree of vulnerability with respect to the development of negative geological processes in it. The new data obtained on the natural control structures of different ranks denudation processes can be useful for the development of innovative geotechnologies that contribute to increasing the land use efficiency, preventing extensive flood zones and increased seismicity, and optimizing natural and economic relationships.
