伊通地堑自１９８７年以来钻井百余口，但用传统方法计算出的资源量与实际勘探结果相差太大。作者利用自己所建立的模拟方法，对本区重新进行了生、排烃和最大聚集量模拟。根据模拟结果，本区已发现的资源量与最大聚集量之比仅为１０％。造成这种情况的原因主要是由于本区沉积物近物源、分选差，使得聚集层与泥岩之间的物性差很小，导致区域性盖层或直接盖层缺乏以及二次运移空间太大，大量油气被吸附或散失在地层之中而难以聚集。
Yitong graben has drilled more than 100 wells since 1987, but the amount of resources calculated by traditional methods is far from the actual exploration results. Using the simulation method established by the author, the author re-generated the hydrocarbon generation, hydrocarbon expulsion and the maximum aggregate simulation. According to the simulation results, the ratio between the amount of resources found in the area and the maximum concentration is only 10%. The reasons for this are mainly due to the near provenance and poor sorting of sediments in this area, which makes the difference of physical properties between the accumulation layer and mudstone very small, resulting in the lack of regional caprock or direct caprock and the secondary migration space Too large, a large number of oil and gas are adsorbed or lost in the formation and difficult to gather.
