|Zones of oil-gas accumulation: methodical approaches to their establishment ensuring the modern solution of problems of an oil-gas-producing branch|
|Developing the theory of forming and typifying the zones of accumulation and zones of oil-gas accumulation is analyzed. The principles of establishing and typifying the zones of oil-gas accumulation are justified on the example of the Timan-Pechora petroleum province. The factors influencing on forming the zones of oil-gas accumulation are analyzed. One of the most important of them is the factor of accumulation zone existence. Such an accumulation zone is a large positive structural element with natural reservoirs (at one or some levels) controlled by regional or zonal seals and connected with oil source rocks enriched in dispersed organic matter during the periods of the most intensive hydrocarbon generation. 209 zones of oil-gas accumulation (73 revealed zones and 136 prospective ones) are established within the basic oil-gas complexes of the Timan-Pechora petroleum province. Preliminary estimating the resource potential of the prospective oil-gas accumulation zones is performed. Establishing the zones of accumulation and oil-gas accumulation zones by choosing the genetically and morphologically one-type objects of searches within (mega-) oil-gas complexes and the quantitative estimation of forecast oil and gas resources of some (mega-) complexes in total allow forming the purposeful and effective programs of studying the territories promising for oil and gas
Key words: accumulation, generation, zone of oil-gas accumulation, oil-gas complex, forecast resources, quantitative estimation, Timan-Pechora petroleum province.
