深层碳酸盐岩原位模拟实验及勘探启示——以川东北地区二叠系为例
In-situ Simulations and Experiments of Deep Carbonate Rocks and Its Implications for Exploration:Take Permian Samples in Northeast Sichuan as an Example
摘要
Abstract
There are two viewpoints about the genesis of dissolution pore in deep marine carbonate rocks in Northeast Sichuan as follows: (1) Early meteoric water and shallow burial dolomitization; (2) Late burial dissolution of fluid. Through in-situ simulations and experiments on Permian samples,it shows that with the increase of depth and temperature, calcite and dolomite are tend to be cement rather than dissolution, and the calcite cement is of greater extent. Therefore, the possibility of deep dissolution is few, while the early diagenesis is the key to the formation of secondary dissolution. The sedimentary facies of marine strata and the evolution law of secondary pores in deep burial stage should be further explored.关键词
