Study on reservoir-forming mechanism of Putaohua reservoir in Hei-dimiao secondary depression, southern Songliao basin
摘要
Abstract
Putaohua reservoir in Heidimiao secondary depression is one of the most important layer in Songliao basin, the paper analyzes the oil-source though oil-source correlation. The result of oil-source correlation shows that, the oil in Putaohua reservoir of Heidimiao secondary depression is mainly from K2n1, source rock. The migration and accumulation mechanism of oil from K2n1 to Putaohua reservoir is analyzed though two conditions in Putaohua reservoir. They are:①enough high overpressure, and ②earliest of K2n1, faults connected K2n1, source rock and Putaohua reservoir. Oil from K2n1, source rock can migrate downward into Putaohua reservoir though earliest of K2n1, faults in the end of K2n, K2m sedimentary period under the action of overpressure. The favorable matching relationship between activity of Tl fault and the periods of hydrocarbon generation and expulsion is the key element making the oil come from K2n1 source rock, and then trapped in Putaohua reservoir. The oil migrated downward into Putaohua reservoir through the earliest of K2n1, fault under the action of overpressure. Hydrocarbon accumulation is controlled by fault and single sand body of K2y1, and based on the oil-source correlation, the character of structure and sediment, the pattern of younger source rock and older reservoir-fault migration system-lithologic reservoirs is summarized.关键词
