Problems solved by technology

The existing simulation experimental device can only provide a single-stage water-rock reaction simulation. The device has a low degree of automation and a simple design, and it is difficult to simulate well the changes in temperature, pressure, and fluid properties in the actual formation caused by geological processes such as structural evolution and subsidence. Dissolution, cementation, metasomatism and other diagenesis

Embodiment 2

[0051] The function of the present invention in diagenesis research will be introduced below through a specific experiment.

[0052] In clastic rock formations, a large amount of carbonate cements can be observed, but it is difficult to find secondary pores formed by the dissolution of carbonates. Instead, the spaces formed by the dissolution of aluminosilicates such as feldspar are secondary pores. This phenomenon is inconsistent with the general understanding that carbonate rocks are more soluble than silicate rocks. Geologists proposed a carbonate regression dissolution model to explain the above phenomenon, that is, a relatively low-temperature shallow buried environment is more conducive to the dissolution of carbonate minerals, and it was proved by thermodynamic calculations. However, there are many unfavorable factors for the proof and interpretation of diagenetic models by means of thermodynamic calculations: 1) the data of thermodynamic calculations mostly come from r...

Description

technical field [0001] The present invention relates to an experimental device in the field of petroleum geology, in particular to a diagenesis simulation experimental device, specifically a diagenesis simulation experimental device equipped with fluid in-situ analysis and permeability on-line detection, mainly used for simulating Dissolution, cementation, metasomatism and other diagenesis caused by changes in temperature, pressure, and fluid properties caused by rising and falling. Background technique [0002] As we all know, resources such as oil and natural gas are decreasing day by day, and it is a general trend to exploit these resources in a more efficient and economical way. Through the study of diagenesis of rock formations, it is helpful to judge whether the research rock formations have the conditions to store oil and gas, thereby improving the efficiency of oil and gas exploration. [0003] Diagenesis refers to the various physical, chemical and biochemical proc...
