摘要
In Dongying faulted lake basin of Shengli oilfield, the controlling actions of palaeo-water depth on the carbonate development are researched. Palaeo-water depth is the important controlling factor to the development of carbonate rock, and the main reason of different types of rock sedimentation controlled by the depth is due to the sedimentary sequences of the chemicaI rocks, the favorable depth for the above development is from 3 m to 32 m. There are a certain difference required by dolomite and limestone to the depth, the most adaptable depths are re- spectively 20 m and 25 m. With the cyclic changes of climate and salinity, multiple period-times limestone-dolomite interbedded sedimentations are formed in vertical.
