pdf Topics about Chayanda oil and gas condensate field: tectonic nature of this accumulations; oil and gas content of the Vendian-Lower Cambrian carbonate section; prospects of the "sub-basement" unit
The tectonic nature of the fields of the Nepa-Botuoba anteclise is considered within the framework of the fluid-dynamic concept. The main element of this concept is basin-forming activated fault systems with the properties of cyclic manifestation, direction of generation, time and period of activation.
It has been established that deposits in the Vendian terrigenous section at the Chayandа oil and gas condensate field were formed under the influence of an activated fault system of the early northeastern generation.The hydrocarbons accumulations in carbonate strata of the Lower Cambrian in the neighboring Talakan oil and gas condensate field under the influence of the system of late northwestern generation are discordant to each other.
According to a number of the considered criteria related to the tectonic nature, the prospects of oil and gas potential of the Vendian-Lower Cambrian carbonate strata on the territory of the Chayandа field are assessed as low. For terrigenous rocks of the Vendian basal strata, the features of the accumulation in the Khamakin productive level in comparison with the Botuobа are established.
Assumptions about the underlying source of subvertical fluid flows of hydrocarbons are argued. It is proposed to study the "basement" unit of the Upper Proterozoic in order to increase the hydrocarbons resource base of the field.

Keywords: fluid-dynamic concept, activated fault system, Nepa-Botuoba anteclise, Chayanda oil and gas condensate field, Botuoba productive level, Khamakin productive level, Vendian-Lower Cambrian carbonates, "sub-basement" unit.
