【摘要】：为研究富台潜山油田有效裂缝分布区域,利用岩心、薄片、流体包裹体分析等资料对富台潜山储层进行系统分析。综合研究结果表明:富台潜山裂缝充填成因主要是深层热液作用;裂缝充填物主要为方解石,少量为硬石膏;裂缝充填受围岩岩性、裂缝性质、热液温度和流速、与断层距离等多种因素控制。富台潜山的裂缝纵向上冶里-亮甲山组、凤山组的白云岩储层充填程度低,上、下马家沟组灰岩充填程度高;平面上背斜轴部远离埕南大断层及二台阶断层的部分充填程度低,靠近这2条断层区域充填程度高;低充填程度区为有效裂缝分布范围。
[Abstract]:In order to study the distribution of effective fractures in Futai buried hill oilfield, cores and thin slices are used. The fluid inclusion analysis and other data are used to systematically analyze the Futai buried hill reservoir. The comprehensive results show that the formation of fracture filling in Futai buried hill is mainly caused by deep hydrothermal action; The fissure filling is mainly calcite and a small amount is anhydrite. Fracture filling is controlled by many factors, such as surrounding rock lithology, fracture nature, hydrothermal temperature and velocity, and distance from fault, etc. The filling degree of dolomite reservoir in Futai buried hill is lower than that in Longitudinal Yili-Liangjiashan formation and Fengshan formation. The limestone filling degree of upper and lower Majiagou formation is high; The partial filling degree of the plane dorsal inclined axis far from the Chengnanda fault and the second step fault is low, and the filling degree near these two faults is high. The area of low filling degree is the distribution range of effective fracture.
