The Relationships Between Evolvement Of Structure And Reservoir Forming Of Block Of Ka 1 In Tazhong Area

The current geologic structure of Tarim Basin is the integrated imaging of stack ithad been reconstructed to original basin in different period of history and differentmovement of structure, so it had an obvious multi-layers in vertical and formed manycombinations of deposit and cover and complex kinds of reservoirs of oil & gas. TheBlock of Ka1 is on the Apophysis of Katake, it is very related with the Tarim Basin inevolvement, it had undergoed many movements of structure, so it had a lot of formatsof structurer, and complex regulation of becoming reservoirs, many times movementand gather, reconstruct, and finally, formed the current traps which had many kinds ofhydrocarbon in different layers. So, it is key step to research the relationship betweenevolvement of structure and becoming reservoir in scientific methods in Block of Ka1in Talimu Basin.The target of research the relationships between evolvement of structure andreservoir forming is to identify the geologic structures, parts and characteristics ofwhole structures through the interpretation and integrated research of seismic sectionsin block, and get the more detail relationship of structure and becoming reservoirthrough the research history of evolvement of structure. Base on the above, with theevaluation of target and zones, the integrated evaluation of the condition of becomingreservoir, potential ability of exploration, target of exploration in whole Block, it willidentify the target of exploration or beneficial zones of exploration.The structure of apophysis is the most important cells of gather of oil & gas inbasin. The shape, format and structure of apophysis in key period and evolvement innext will influence geologic format of basin and restrict gather and distribution of oil& gas.After forming of ancient apophysis, it will have different format with the differentaffects of movement of structure in the long evolvement of history of geology. Theancient apophyssis had different forming of structure, different extent of growth ofparts and different restricted ability to distributing of growth of stratum in differentgeologic period.The basic elements of reservoir forming are source, reservoir, cap, trap, migration,gather, preserve of oil & gas, it includes the basic elements of reservoir forming andthe mostly related factors in reservoir forming. With the research of currentinformation in Katake, people think there are four mostly factors of reservoir formingin west incline in Katake, those are fountain, passage, layer of store, structure. Amongthose factors, the most important factor is evolvement of structure of basin, it madethe distributing of rocks of hydrocarbon, developed the available times of reservoirforming, made an abundant shapes and format of reservoir, controlled thecharacteristics of current oil & gas.
