    摘要:

    为了对断层输导能力进行定量评价,将其表征为与油气资源量成线性正相关关系的、单位时间内断层输导的油气资源量,其影响因素包括烃源岩排烃强度、主要成藏期断层古落差、成熟烃源岩内部断层平面延伸长度和断层停止活动时间。采用断层输导能力定量评价公式对济阳坳陷青西地区的油气勘探潜力进行了研究。结果表明,当断层输导能力与油气资源量拟合的常数取值为210时,断层输导能力之和与邻区辛镇油田东部和研究区永安镇油田对应的探明石油地质储量具有良好的线性正相关关系。拟合结果表明,永101、永106和永116井区位于油源断层附近,圈闭发育,能量半衰时梯度异常,为有利勘探目标;预测新立村油田沙四段上亚段、沙三段约有1 800×104 t的石油地质储量有待发现。

    Abstract:

    The quantitative capacity evaluation of the fault transporting, defined as hydrocarbon resources transported by faults in unit period, has a linear direct ratio relationship with the hydrocarbon resources. The influence factors are expulsion intensity of hydrocarbon, ancient fault throw in reservoir forming period, plane extension length of faults in matured source rock and inactive period of faults. The hydrocarbon exploration potential in west Qingtuozi uplift of Jiyang depression was evaluated by the equation of fault transporting ability. The results show that when the ξ value at 210, there is a very good linear related relationship between total fault transporting capacity and local oil geological reserves in east Xinzhen oilfield (near the research area) and Yonganzhen oil and gas field. According to the fitting results, 18 billion tons of potential oil reserve in Xinlicun oilfield are existed in the Es3 member and Es4 upper section, and need to be located. The Yong101, Yong106, and Yong116 well district in Xinlicun oilfield are the favorable exploration targets, which have favorable hydrocarbon accumulation condition such as adjacent to the source faults, developed trap and abnormal energy-half-time.
