摘要

摘要: 该文针对勘探程度较高的沾化凹陷中部渤南洼陷渤南油田沙三段,在进行了高分辨率层序地层学研究的基础上,进行了沉积微相研究,发现了重要的油气勘探目标——沉积叶状体。渤南洼陷沙三段时期来自于孤岛凸起的主要物源和罗家鼻状构造的次要物源,形成了深水湖泊浊积扇沉积体系,包括内扇、中扇、外扇3个亚相以及内扇补给水道、内扇阶地、内扇天然堤、中扇辫状水道、中扇叶状体、外扇席状砂6个微相,其中以浊积扇中扇亚相为主。中扇叶状体呈透镜状被沙三段烃源岩包围,形成极好的岩性圈闭油气藏,是渤南油田新的油气勘探目标。

Abstract: Aimed at high exploration degree of the Sha-3 Member in Bonan oilfield, the Bonan Sag of the Middle Zhanhua Depression, the sedimentary microfacies were studied on the base of high-resolution sequence stratigraphical research, and sedimentary lobes were found as important targets for hydrocarbon exploration. During the Sha-3 period of the Bonan Sag, the essential sources from the Gudao convex and the secondary sources from the Luojia Nose formed the deep-lake turbidite-fan sedimentary system, including endofan, mesofan and exofan three subfacies and endofan feeding channel, endofan terrace, endofan natural levee, mesofan braided channel, mesofan lobe and exofan sheet sand six microfacies. Among them, the turbidite-fan mesofan subfacies was dominant. The mesofan lobes were lens-shaped and enclosed by the hydrocarbon source rocks of the Sha-3 Member. They formed excellent oil and gas pools of lithologic traps, and were new targets for hydrocarbon exploration in Bonan oilfield.
