Characteristics and forming mechanism of buried hill reservoir of Lower Paleozoic in Zhuangxi-Chengdao area
Online published: 2009-03-16
The characteristics of buried hill reservoir in Zhuangxi-Chengdao area are studied, and the reservoir space types are analyzed. It is pointed out that the reservoir space is composed of karst reservoir and pore reservoir. Karstification is the main forming mechanism of the carbonate karst reservoir near the unconformity, and the depth
influenced by atmogenic freshwater is about 150 munder the Caledonian unconformity. Dolomitization is the important forming mechanism of buried hill reservoir. The reservoirs of Yeli-Liangjiashan Formation are mainly concerned with dolomitization during the buried processing, especially concerned with the volume contraction of grains.
