Abstract

The relevance. The Bureya sedimentary basin is the most interesting in respect of oil and gas intermountain basin of frontier mainland of Russian Far East. An upbeat assessment of prospects of oil and gas field discovery in the basin is proved by the results of previous pro' specting work and scientific research. The aim of this paper is further argumentation of hydrocarbon prospects of upper Jurassic'lower Cretaceous deposits in the Bureya ba' sin based on the use of domestic basin modeling software TeploDialog, having original features. Study object is middle'upper Jurassic, upper Jurassic'lower Cretaceous and Cretaceous sedimentary sequences of the Kyndal graben, the most studied structure in the Bureya fore deep. The previous investigations have revealed that the whole Jurassic'Cretaceous section of the Bureya basin is involved in oil'and'gas formation. Methods. In the software TeploDialog the paleotemperature modeling method is implemented based on the numerical solution of heat' transfer equation of a horizontally layered solid with a movable upper boundary. Mathematical model includes climatological secular trend of temperatures on the earth surface (boundary condition) and paleotemperatures from vitrinite reflectance evaluation (observa' tional). The method does not require a priori information about the nature and magnitude of the deep heat flow, the heat flow is deter' mined by the solution of the geothermal inversion within the framework of parametric description of the sedimentation history and the history of the thermophysical properties of sedimentary strata. Results. The study found that geothermy of graben since Jura permitted formation of liquid hydrocarbons in the sedimentary cover rocks, which could begin about 107 million years ago, in the middle of the Alb. The most intensive oil generation took place in the period of 107–40 million years ago, until the middle of the Eocene. Temperature conditions for the generation of liquid hydrocarbons are still the same for talyndzhansky kitchen. Maximal duration of temperature periods, favourable for gas formation is observed in chemcukin' sky kitchen. The conditions for gas generation are still the same for urgalsky and chegdomynsky kitchens. The results obtained using the domestic software TeploDialog and previously obtained in software PetroMod, strongly aligned. These computer programs are charac' terized by different approaches to consideration of tectonic'sedimentation and thermal conditions of hydrocarbon generation. There' fore, the results of this study are an additional argument for the positive prospects of oil and gas potential of the upper Jurassic'lower Cretaceous deposits of the Bureya basin.
