葵花岛构造勘探目的层分为常规储集层和非常规储集层两类。东营组属于常规储集层,沙河街组属于非常规储集层。沉积环境是影响该区储集物性的主要因素,成岩作用对储集物性具有重要的改造作用,岩性及裂缝发育程度对储集物性有一定的影响。
Sunflower Island structural exploration target layer is divided into two types of conventional reservoirs and unconventional reservoirs. Dongying Formation belongs to conventional reservoirs and Shahejie Formation belongs to unconventional reservoirs. Sedimentary environment is the main factor affecting the reservoir physical properties. Diagenesis plays an important role in the reservoir property alteration. The lithology and the degree of fracture development have a certain impact on the reservoir properties.
