Abstract:

The development degree of natural fractures is a critical factor affecting single-well productivity of Jurassic Qigu Formation in Yongjin area， Junggar Basin. Based on data of field outcrops， cores， thin sections， well logging and experiment， genesis types， development characteristics， and main controlling factors of natural fractures in tight sandstone of Qigu Formation were studied, and favorable development areas were predicted. The results show that：（1） Genesis types of natural fractures in tight sandstone reservoirs of Jurassic Qigu Formation in Yongjin area， Junggar Basin are various， mainly including diagenetic fractures， a small number of structural fractures and abnormal overpressure fractures. The diagenetic fractures are mainly bedding fractures， and a small number of marginal and intragranular fractures are developed. Natural fractures are one of the important factors in the formation of deep high-quality reservoirs. （2） The development of fractures in Qigu Formation in the study area is primarily controlled by sedimentation, tectonic stress， and overpressure. Sedimentary microfacies control the degree of fracture development by controlling factors such as lithology， mineral composition， and sedimentary structure. The medium-fine grained sandstone in the middle to upper parts of the diversion sand dam is a favorable location for fracture development. The near north-south structural compression stress during Himalayan tectonic period acts as a key driving force for the initiation and propagation of structural fractures and bedding fractures， and fractures are more developed within 1 km of the fault. Abnormal overpressure exerts a critical influence on the formation of overpressure fractures and bedding fractures， as well as the preservation of fractures. In the northern part of the study area， abnormal overpressure is highly developed， reservoir fractures are relatively developed. （3） The effective natural fractures of Qigu Formation in the study area primarily develop in the layered distributary sand dam in the northern part of the fault, where the pressure coefficient exceeds 1.6.

Key words: tight sandstone, natural fracture, diagenetic fracture, structural fracture, abnormal overpressure fracture, Qigu Formation, Jurassic, Yongjin area, Junggar Basin
