The basic trap conditions in trap geological evaluation include factors such as reservoir-caprock combination, trap area, and the location of trap.
查看答案
The geological conditions in trap geological evaluation mainly include trap shelter conditions, oil and gas reservoir conditions, hydrocarbon source conditions, preservation conditions, supporting conditions and reliability conditions.
In the process of trap preparatory prospecting, the core work of trap evaluation is geological evaluation.
The reliability of traps can be evaluated qualitatively or quantitatively.
The reliability of traps is mainly evaluated based on the complexity of the traps, the abundance of seismic data and the distribution of wells drilling.
