The Thermodynamics Equilibrium Condition of Carbonate Minerals in Strata Environment and Iu's Application in Kela 2 Gas field,Kuqua Depression

Abstract: Based on the thermodynamics equilibrium theory and the reality in Kuqua depression,in this paper two diagenetic reactions in strata environment have been conducted,including the calcite dissolution and the replacement of dolomite to calcite.Furthermore,according to characteristics of oilfield water,the current situation of calcite dissolution and replacement of dolomite to calcite have been discussed.Lots of information implies that the two diagenetic reactions are carrying out in oilfield water;the dissolution of calcite cement is essential factor for the deep-buried secondary porosity anomaly in this area.

Analysis of the migration direction of two different types of petroleum in composite overpressure hydrocarbon generation system in Niuzhuang Subsag

Abstract: There is a composite overpressure hydrocarbon generation system in Niuzhang Subsag,Jiyang Sag.It is composed of two sets of vertically superimposed source rocks (Es3x and Es4s),and there is over-pressure of fluid in it.The two sets of source rock are different in organic geochemical feature,hydrocarbon generation periods and hydrocarbon migration and accumulation process.According to oil-source correlation and the spatial distribution law of homologous hydrocarbon reservoirs,the difference in the hydrocarbon migration direction of the two sets of source rock is studied.It is shown that the hydrocarbon from Es3xsource rock mainly vertically migrates under the induction of fault activities;while the hydrocarbon from Es4s source rock mainly laterally migrates underneath the overpressure cap rock,the vertical migration is not active in the overpressure development area.The self-organization effect of the overpressure hydrocarbon generation system obviously controls the directions of hydrocarbon migration,which causes the greater difference in the migration direction and distribution law of the hydrocarbon from Es3x and Es4s.The analysis of the migration direction of the hydrocarbon from different oil sources in the composite overpressure hydrocarbon generation system can provide help for the recognition of the hydrocarbon migration and accumulation law and the hydrocarbon exploration potential.

Optimized structural parameters and heat extraction capacity of a mixing device for constant pressure CO2 mineralization using alkaline waste

Abstract: Alkaline waste such as calcium carbide slag is an ideal material for mineralizing CO2 and promoting atmospheric carbon reduction. In this study, the structural parameters of a mixing device and a thermal extraction method for the high-efficiency mineralization of CO2 using alkaline waste were optimized. First, the influence of structural parameters was studied by means of numerical simulation, and it was found that when the length-diameter ratio, blade angle, spacing, and diameter of the mixing device were 3, 15, 6 cm, and 14 cm respectively, 2.14 t CO2 can be mineralized within 1 h. The amount of heat extracted from mineralization of 1 t CO2 reached 189.60 MJ. In addition, the winding configuration of the heat pipe, which is beneficial for extracting more reaction heat, was optimal, and a model of the relationship between the heat pipe outlet water temperature and flow velocity at the outlet of the heat pipe was established. This study provides theoretical guidance for the field application of alkaline waste for high-efficiency mineralization of CO2, which can accelerate the realization of peak CO2 emissions and carbon neutrality.
