摘要
古潜山油气藏分布规律严格受构造带控制 ,断陷盆地不同构造带及其演化特点 ,决定了不同构造部位具有不同的古潜山圈闭体系和油气藏形成条件。济阳坳陷“古潜山”圈闭体系按二级构造带可划分为高潜山油气藏体系、中潜山油气藏体系和低潜山油气藏体系。其勘探程序依次为 :区域构造带研究 ,确定古潜山展布区 ;潜山构造特征研究 ,落实潜山顶面及内幕储层构造形态 ;油气源及油气运聚分析 ,落实潜山油气藏形成类型 ;有利储集层预测 ,利用地震储层预测技术寻找有利储集相带 ;综合分析 ,评价潜山油气藏勘探潜力和规模 ,设计探井。通过对济阳坳陷潜山油气藏进行体系的划分和勘探技术与方法的优化 ,近期在低潜山的车 3、中潜山的CBG4和CB30、高潜山带的广饶潜山的勘探中取得了突破。
Distribution of buried hill reservoir was strictly controlled by structure belt. Different structure and evolution features of a rifted basin made different buried hill trap systems and reservoir forming conditions in different locations. 'Buried hill' trap system of Jiyang depression can be divided into high, medium and low reservoir system of buried hill according to secondary structure. Exploration programs in turn are regional structure study to determine distribution area of buried hills; buried hill structure study to delineate the top of buried hill and interior structure of reservoir; analysis of oil source, migration and accumulation to determine reservoir forming conditions; projection of favorable reservoirs through seismic technology; and integrated analysis to evaluate the potential and scale of exploration and to design exploration well. Through system division and optimization of exploration technologies for buried hill reservoirs of Jiyang depression, breakthroughs had been achieved in recent exploration in Che 3 lower buried hill, CBG4 and CB30 medium buried hill, and Guangrao higher buried hill.
