Abstract
Alkaline diagnesis is a diagenetic process that a reservoir undergoes under an alkaline environment. Because of the influence of alkaline formation water, the most typical characteristics of diagnesis is that quartz is obviously dissolved, feldspar is massively enlarged, and less late carbonate cement is formed in the evolution of carbonate minerals. With the decrease of the alkalinity of the formation water in diagenesis, the quartz overgrowths become common. The change in the chemical characteristics of the formation water leads to a more complex distribution of reservoir porosity at different depths than that of the secondary porosity formed by classical acidic water. It also makes the stage of early diagenesis the important development period of secondary porosity.
