Embodiment Construction

[0060] Such as figure 1 As shown, the specific implementation mode adopts the following technical solutions: comprising the following steps:

[0061] 1. Proportion and design of "artificial core"

[0062] Artificial cores are the basis of mechanical compaction experiments and water-rock simulation experiments. Whether the proportioning scheme is reasonable is of great significance to subsequent research. According to the actual rock type and sandstone particle size of high-temperature and overpressured reservoirs, artificially proportioning clastic rocks In this way, the specific proportioning scheme is:

[0063] (1) According to the content of clastic components in the study area, the relative percentages (mass percentages) of skeleton clastic particles and clastic clays in different layers and different structural divisions were counted, that is, quartz, potassium feldspar, Plagioclase, detrital clay and different types of cuttings were normalized, and their relative conte...

Abstract

The invention discloses an experimental method for evolution simulation of a high-temperature and overpressure reservoir, and belongs to the technical field of high-temperature and overpressure reservoirs; an artificial core is the basis of a mechanical compaction experiment and a water-rock simulation experiment, whether the ratio scheme of the artificial core is reasonable or not is of great significance to follow-up studies, according to the actual rock type of the high-temperature and overpressure reservoir and clastic rock samples of which the sandstone grain sizes are artificially proportioned, the specific ratio scheme comprises the following steps that the relative percentage contents of skeleton clastic particles and clastic clay of different horizons and different tectonic divisions are counted according to the content of clastic components in a study area; the content of authigenic minerals in the proportioning process is not considered to restore the appearance of the clastic particles while depositing; the difficulty of the proportioning process lies in the distinction between the content of clastic clay minerals and the content of authigenic clay minerals. On the basis of the artificially proportioned rock samples, the mechanical compaction experiment and the water-rock simulation experiment are used to explore the effect of high temperature and overpressure on reservoir evolution and main control factors of a high-quality reservoir so as to guide favorable lithologic trap evaluation and later exploration and development of oil and gas to lower the cost.

Description

technical field [0001] The invention relates to the technical field of high temperature and overpressure reservoirs, in particular to an experimental method for evolution simulation of high temperature and overpressure reservoirs. [0002] Background technique: [0003] In the prior art, the experimental method for the evolution simulation of high temperature and overpressure reservoirs is relatively simple, and the experimental results have many instabilities, and the data are not accurate enough. Contents of the invention [0004] In view of the above problems, the technical problem to be solved by the present invention is to provide an experimental method for high temperature and overpressure reservoir evolution simulation with reasonable design and convenient operation. [0005] A kind of experimental method aiming at high temperature, overpressure type reservoir evolution simulation of the present invention, it comprises the following steps: [0006] 1. Proportion and...
