Abstract

The invention relates to the field of petroleum geology, and particularly relates to a rock-fluid reaction in situ observation device capable of controlling temperature and pressure. According to the specific technical scheme, the rock-fluid reaction in situ observation device comprises a reaction body, a sealed reaction chamber formed in the reaction body and an observation mechanism capable of observing rock slice reaction in the sealed reaction chamber, wherein the reaction body is provided with a gas-liquid inlet mechanism and a liquid circulating mechanism, the gas-liquid inlet mechanism comprises a gas inlet and a liquid inlet which are formed in the reaction body, with one ends of the gas inlet and the liquid inlet are communicated with the exterior of the reaction body and the other ends of the gas inlet and the liquid inlet are respectively communicated with the reaction chamber through a connecting channel, and a gas inlet control valve capable of blocking or opening the gas inlet and a liquid inlet control valve capable of blocking or opening the liquid inlet are respectively arranged at the gas inlet and the liquid inlet. By adopting the technical scheme, the invention provides the rock-fluid reaction in situ observation device capable of controlling temperature and pressure, which has the advantages that the experiment time is shortened and the experiment effect is improved.

Description

technical field [0001] The invention relates to the field of petroleum geology, in particular to a rock-fluid reaction in-situ observation device with controllable temperature and pressure. Background technique [0002] Water-rock simulation reaction is a commonly used experimental method in petroleum geology. The main purpose is to clarify the formation of pores in sandstone oil and gas reservoirs, and provide important clues for the prediction of high-quality oil and gas reservoirs. At present, four kinds of experimental devices are mainly used in water-rock reaction experiments: one is to use glass containers to heat direct reactions, simulate water-rock reactions under near-surface conditions, and analyze the concentration changes of different anions and cations; the other is to use high-temperature and high-pressure reactors to simulate The water-rock reaction in a closed system under similar formation conditions mainly simulates the dissolution of feldspar in different...
