摘要
杏北开发区非主力油层为三角洲前缘亚相沉积,可划为内前缘、外前缘I类、外前缘Ⅱ类、外前 缘Ⅲ类、外前缘Ⅳ类和前缘砂坝6类微相;油层具有发育层数多、渗透率低、单层厚度薄等特点;通过 地质调查．查明了各类微相的地质储量和剩余油分布状况,制定了注采系统相对完善、注采关系不完善、 井网控制不住型剩余油的挖潜对策。
The non-main reservoirs in Xingbei development area are delta frontier subfacies depositions, which can be di-vided into 6 microfacies, such as internal front margine, external front margines I?????IV and front sandbar, the reservoirs have the characters of multiplayer. low permeability, small single layer thickness. Through a geologic investigation? geologic reserves and residual distribution are found out for each microfacies? the countermeasures for tapping the potential of residual oil are established, ...
