东噗凹陷以深层天然气资源丰富而著称,但多年来的数十日深井钻探效果不理想。人们将其原因归结为“储集层物性差”,即使局部存在良好储集层也“难以捉摸”。这是以“深盆气”为模式,以岩性和小村造圈闭为对象进行钻探得出的结论。通过综合研究认为,东濮凹陷的洼陷带中存在规模较大的古构造,圈闭条件好,它们的形成时期与油气生成、运聚时期相匹配,因而较早捕获油气,并使圈闭范围内的储集层保留了较好的原始孔隙,减缓或抑制了水化学作用导致的储集物性变差,是深层天然气勘探的有利目标。提出洼陷带深层气勘探仍应以构造圈闭为主要对象的认识,认为西部洼陷带南部的长垣断裂构造带和李家-林寨村造群是深层气勘探的有利地区。
Dong Po Sag is known for its deep natural gas rich resources, but the deep well drilling effect on the dozens of days over the years is not satisfactory. The reason is attributed to the “poor reservoir properties”, even if the existence of a good local reservoir “elusive.” This is the conclusion drawn from drilling in the “lithosphere” and “small village trap” as a model of “deep basin gas”. According to the comprehensive study, there is a large-scale palaeo-tectonic structure in the depression of Dongpu Depression with good trapping conditions. Their formation period is matched with the periods of hydrocarbon generation and migration, so oil and gas are trapped earlier and trap The reservoirs in the area retain good original pores, slowing down or inhibiting the deterioration of reservoir properties caused by water chemistry, which is a favorable target for deep-seated gas exploration. It is proposed that deep subsidence zone deep gas exploration should still be based on structural traps. It is believed that the Changyuan fault zone and the Lijia - Linzhai formation in the southern depression are favorable for deep gas exploration.
