断裂在海相碳酸盐岩储层形成过程中发挥了重要作用,但塔里木盆地哈拉哈塘地区受多期构造活动、岩溶改造及地震资料品质的影响,断裂一直是研究的难点,制约了该区的油气勘探。通过构造解析,厘清了该区断裂期次与断裂性质,查清了走滑断裂发育的多种典型构造,并通过物探技术开展断裂平面展布规律研究。以此为基础,明确了走滑断裂控制了裂缝发育区和储层的展布,认为线性构造带储层发育范围有限,花状构造及辫状构造带储层发育良好,羽状构造带储层发育范围及规模最大。断裂交会裂缝发育区对储层改造作用最为显著,是寻找高效井点的理想场所。
Fractures play an important role in the formation of marine carbonate reservoirs. However, faults are always the difficult point of research due to the multi-period tectonic activities, karstification and seismic data quality in the Halahatang area, Tarim Basin. Oil and gas exploration in the area. By means of tectonic analysis, the fault times and faults in this area are clarified. Many typical tectonic developments of strike-slip faults are identified, and the study of fracture plane distribution rules is conducted by geophysical techniques. Based on this, it is clear that the strike-slip faults control the distribution of fractured development zones and reservoirs, and the range of reservoir development in the linear tectonic zone is limited. The reservoirs in the flower-shaped structure and the braided tectonic zone are well developed. The feather- Layer development and the largest scale. Fracture rendezvous fracture development zone is the most significant to the reservoir reconstruction, is an ideal place to find efficient well point.
