摘要:

根据塔里木盆地顺北地区走滑断裂带发育背景,结合里德尔剪切模式,利用地质力学理论分析不同走滑构造样式下优势裂缝发育特征,以及不同构造分段裂缝系统有效性的改造作用,同时探讨了裂缝发育特征及地应力对产能的控制作用。研究表明,走滑断裂的组合关系控制局部应力状态及裂缝发育模式;走滑断控储集层油气产能受控于应力场特征、新生裂缝产状与先存优势裂缝产状;剪切走滑构造段派生的裂缝及小规模断裂组合使断裂带有效性变高,该区域井产能普遍较高。

Abstract:

According to development background of the strike-slip fault zones in the Shunbei area of Tarim Basin, combined with the Riedel shear model, the development characteristics of dominant fractures of different strike-slip structural styles and the reworking of the effectiveness of fracture systems in different structural segments are analyzed by using the theory of geomechanics, and the controls of fracture and in-situ stress on productivity are clarified. The research shows that the combination of strike-slip faults controls the local stress state and fracture development pattern. The oil and gas productivity of the strike-slip fault-controlled reservoirs is controlled by the characteristics of stress field, and the occurrences of new fractures and pre-existing dominant fractures. The combination of small-scale faults and fractures derived from the strike-slip structural segments increases the effectiveness of the fault zones, and the well productivity in this area is generally high.

Key words: Tarim Basin, Shunbei area, strike-slip fault, fracture characteristic, stress distribution, productivity
