The risk probability evaluation method in the trap effectiveness evaluation method mainly considers the five accumulation conditions of trap quality, trap control degree, reservoir, source rock, and cap rock.
查看答案
There are many trap effectiveness evaluation methods in the process of trap exploration. Commonly used methods include geological analogy method, risk probability method, and fuzzy comprehensive evaluation method.
The success rate of trap exploration is the percentage of traps that obtain industrial oil and gas flow in the prospective traps.
The supporting conditions in the preservation conditions of trap geological evaluation mainly refer to the spatial configuration relationship of trap conditions, reservoir conditions, source rocks and preservation conditions.
The factors considered in the preservation conditions of trap geological evaluation mainly include caprock lithology and its development degree, tectonic activity, hydrological conditions and so on.
