Mine water geology parameter monitor

ActiveCN119334415BMonitor temperature in real timeReal-time pH monitoring
The present application relates to the technical field of mine production, and specifically discloses a mine water geological parameter monitor, which comprises a mine water geological parameter module, a water quality state analysis module, a mine safety analysis module, a water disaster risk assessment module, a monitoring and early warning terminal and a database. By installing appropriate sensors on the mine water geological corresponding monitoring points and making them in communication connection with the mine water geological parameter monitor, real-time monitoring and acquisition of the water quality, gas and hydrological parameters of each monitoring point in each monitoring period can be realized. The mine water geological parameter monitor can monitor the temperature, pH value, conductivity, dissolved oxygen content and suspended solids content of the mine water in real time, as well as the methane concentration, carbon dioxide concentration, oxygen concentration and gas release rate. In addition, the mine water geological parameter monitor can also monitor the water inflow, water level value, water storage volume and drainage flow, thereby providing accurate and reliable data support for mine water management.

Quantitative evaluation method for stability of tight oil reservoir cement sheath

The invention discloses a quantitative evaluation method for the stability of a tight oil reservoir cement sheath, which comprises the following steps: 1) acquiring well cementation cement, measuring basic parameters of main substances in the well cementation cement, carrying out an underground cement well cementation simulation experiment, and measuring basic parameters of a cement sheath sample after reaction; 2) taking the particle size as a separation point, dividing the cement substance into an unreacted inclusion and a full-reacted body, calculating the average thickness of the outer ring of the unreacted inclusion, obtaining a thickness-diameter curve, calculating the ratio of the thickness to the particle size of the unreacted inclusion with different particle sizes, and re-representing the large-particle-size combination distribution state of the substance after the cement reaction; and 3) calculating the filling degree of the small-particle-size substances according to the porosity and the effective porosity of the cement sample, defining the unfilled small-particle-size substances and the unreacted inclusion substances as free substances, and calculating a stability coefficient according to the composition state of the free substances to evaluate the well cementation quality. The stability is determined according to the particle distribution state before and after the cement sheath reaction, and the method is more scientific and economical.
