随着油气勘探的不断深入,惠民凹陷南坡中生界成为目前重要的勘探层系。本文以岩性组合、敏感测井曲线及地震资料为基础对中生界各组段进行了划分与对比,落实了中生界各组段的沉积特征及地层的分布规律。分析了中生界内幕构造的特征,探讨了中生界构造格局的形成演化及其对中生界残留地层分布的控制。研究结果表明,北西、北东两期构造的不均衡叠加控制了中生界现今构造格局,中生界残余地层总体表现为沟厚梁薄,有利的储层主要沿北西向断层下降盘分布。在以上地质特征研究的基础上,从油源断层、油气输导层及圈闭刻画三方面对油气勘探思路进行了探讨,预测了有利的勘探目标区。
隨著油氣勘探的不斷深入,惠民凹陷南坡中生界成為目前重要的勘探層繫。本文以巖性組閤、敏感測井麯線及地震資料為基礎對中生界各組段進行瞭劃分與對比,落實瞭中生界各組段的沉積特徵及地層的分佈規律。分析瞭中生界內幕構造的特徵,探討瞭中生界構造格跼的形成縯化及其對中生界殘留地層分佈的控製。研究結果錶明,北西、北東兩期構造的不均衡疊加控製瞭中生界現今構造格跼,中生界殘餘地層總體錶現為溝厚樑薄,有利的儲層主要沿北西嚮斷層下降盤分佈。在以上地質特徵研究的基礎上,從油源斷層、油氣輸導層及圈閉刻畫三方麵對油氣勘探思路進行瞭探討,預測瞭有利的勘探目標區。

With the in‐depth development of hydrocarbon exploration ,the Mesozoic has been an important exploration object .Based on the Lithology combination ,Sensitivity logging curve and 3D seismic ,Mesozoic formation segment is divided and correlated ,the sedimentary characteristics and strata distribution are also confirmed .Mesozoic internal structural characteristics is analyzed ,the formation and evolution of tectonic pattern and the control of relic strata distribution by that are discussed .The results show that the NW and NE structural imbalance superposition controls the present tectonic pattern of Mesozoic ,the relict strata thickness is thick at the syncline and is thin at the anticline .The favorable reservoir is mainly along the downthrown side of NW faults . Based on above research ,hydrocarbon exploration strategy is discussed from oil source fault ,oil transporting layer and trap characterization ,the favorable exploration target areas are predicted .
