本文从古地温演化的途径,阐明相邻两个凹陷生油潜力之所以产生差别的原因。 古地温演化图表明,Es_3末期的地壳抬升作用,对饶阳凹陷的影响甚小,该区以持续的升温为主,至东营期末,Es_3部分达到门限温度;至明化镇末,则Es_3大面积达到门限温度。廊固凹陷与前者显然不同,因Es_3末期地壳抬升,使主要生油岩系Es_3在明化镇期末大多未达到门限温度。这就是生油潜力不及饶阳凹陷的主要原因。
In this paper, the evolution of paleogeothermal from the way to clarify the potential difference between the two adjacent oil production potential reason. The paleo-geothermal evolution maps show that the uplift of Es3 in the end of Es3 had little effect on the Raoyang depression, and the area was dominated by continuous warming. At the end of Dongying period, Es3 partially reached the threshold temperature; at the end of Minghua, Es3 The area reaches the threshold temperature. The Langgu Sag is obviously different from the former. Because of the late crust uplift of Es_3, most of the oil-producing rock series Es_3 did not reach the threshold temperature at the end of Minghua Town. This is the main reason why the oil production potential is less than that of the Raoyang Sag.
