13 The Model of the Multi-Stage of Oil-Gas Formation and Exploration Effectiveness in Superimposed Basins in Western China KANG De-jiang JIANG Li-na ZHANG Jin-you Research Institute of Petroleum Exploration & Development of Daqing Oilfield Co. Ltd. Daqing Heilongjiang Abstract By comparing the large and medium-sized oil and gas fields it is discovered that reservoirs in superimposed basins are most of multi-stage formation process and the late accumulation is favorable for large-scale preservation. Based on summary of accumulation progress characteristic and model of the vorious oil-gas pool combined with features of the tectonic evolution of the study area it composes the hydrocarbon accumulation pattern classification and divides oil and gas multi-phase accumulation model into 5 types according to the criteria continuous oil-gas filled early strong reformation strongly reworked in medium-term late strongly reworked and alternation of multistage filling and reworked. Strength of structural changes and occurring period are taken into account to construct the pattern classification criteria and the two parameters are all relative. The characteristic of continuous oil-gas filled is that the oil and gas transportation capability is strong and it can not only form the normal reservoir but also the pyrolysis gas reservoir. The early strong reformation means the strength of structure is more stronger and the range is larger during the early period it makes the hydrocarbon expelled from resource can not be assemble in the suitable trap in contrast the later oil and gas can form the reservoir. Strongly reworked in medium-term mode indicates that much of tectonic movements strongly happened after the reservoir accumulated oil and gas reservoirs will be reformed or lost to some extent each time so the late contribution is the main result of this type. The late strongly reworked type means that the hydrocarbon formed and expelled from source all accumulated in the relatively stable environment and in the late there happens the strong and large-scale tectonic movements these movements change the existed reservoirs in the aspect of quality and quantity. The last one is multi-stage filling and reworked type which most occurs in the region happened strong and frequent extremely tectonic movements. Although the reservoirs formed early strong tectonic movements destroy or change them all after several times it basically can not form a large reservoir. Among the model of the multi-stage of oil-gas formation listed above the first type can form the typical reservoir under normal circumstance moreover the condensate gas reservoir is more. The second one is similar to the forth type but because the time of destroy is different the corresponding results are very different. Early strong reformation type can destroy the reservoir accumulated in the early stage seriously and because of the later stable tectonic movements it can preserve the hydrocarbon formed in the later period such as the distribution of Silurian bituminous sandstone in Tazhong region and much of reservoir existed in Carboniferous and Thriassic. The third one can preserve the earlier reservoir to some extent and meanwhile it also can accumulate the late hydrocarbon because the strength of the tectonic movements become weaker. The characteristic of the forth type is the strength of tectonic is very strong and it can be destructive. To the maximum extent it can completely destroy the former reservoirs the remaining is very little. The last type is a model without exploration effectiveness and the result of structural damage is highly visible So the resource accumulated under this condition is restricted extremely. In the context of late accumulation is favorable for exploration it determine that the region with the model of continuous oil-gas filled and surrounding areas is most likely to accumulate large scale and many types of oil-gas reservoirs because there have little tectonic movements and the damage. However the model of alternation of multi-stage filling and reworking have little exploration effectiveness because of many tectonic movements and damages. Consequently the exploration for oil-gas should try to avoid these areas. Key words superimposed basin model of multi-stage accumulation exploration effectiveness late accumulation tectonic movement
