摘要

对储层沉积物的地质力学特性进行适当研究,可以准确预测不同应力机制的大小和方向。这对油气生产和开发至关重要,尤其是在变形和构造受控的含油盆地。西部沙漠北部(NWD)的断裂盆地为这些受构造控制的富油气区提供了类比,在这些地区,侏罗纪沉积接替的同步断裂构造承载着富油气藏目标。然而,对侏罗纪储层地质力学行为的详细评估却从未进行过调查。因此,本研究利用有线测井数据确定了西北干旱区蜀山盆地哈特巴地层侏罗系同步断裂面的地质力学性质。通过构建地球力学模型和解释地层微成像测井仪(FMI),研究了所研究变形面的地质力学行为和井筒稳定性。通过识别钻井引起的裂缝、断裂带和地层裂缝,根据 FMI 确定了应力方向。电阻断裂、导电断裂和部分导电断裂的走向分别为东北-西南、东南-西南、西北-东南、东北-西南和西南-东北,与侏罗纪同步裂谷构造相吻合。ENE-WSW方向的断裂和最小水平应力(SHmin)与研究区域的主断层方向相同,与NNW-SSE方向的最大水平应力(SHmax)和诱导断裂形成鲜明对比。本研究强调了综合有线测井结果在解释临界和非临界应力方向方面的重要意义,这对于在全球各地受构造控制的多产盆地制定最佳生产计划十分必要。

Analysis of the geomechanical properties of the Jurassic Khatatba reservoir in Shushan Basin, Egypt and its implications for wellbore stability assessment

A proper investigation of geomechanical properties of reservoir sediments allows accurate prediction of both magnitude and direction of different stress regimes. These are crucial for hydrocarbon production and development particularly in deformed and structurally controlled petroliferous basins. The rift basins in the north Western Desert (NWD) provide analogues for these structurally controlled prolific regions, where the syn-rift Jurassic sedimentary successions host prolific reservoir targets. However, a detailed assessment of the geomechanical behavior of the Jurassic reservoirs has never been investigated. Thus, the present study utilizes wireline log data to determine the geomechanical properties of the syn-rift Jurassic facies of the Khatatba Formation in Shushan Basin in the NWD. Mechanical earth model was constructed and formation microimager logs (FMI) were interpreted for to investigate the geomechanical behavior and wellbore stability of the studied deformed facies. The stress direction was determined from FMI by identifying drilling-induced fractures, breakout zones and formation fractures. Resistive, conductive and partially conductive fractures are oriented in NE–SW, ESE–WSW, NW–SE, NE–SW and SW–NE directions coinciding with the Jurassic syn-rift structures. The ENE–WSW direction of breakout and minimum horizontal stress (SHmin) are the same as that of the primary fault in the study region contrasting with the NNW–SSE direction of maximum horizontal stress (SHmax) and induced fractures. The present study highlights the significance of integrating wireline logging results in interpreting the critical and non-critical stress orientations which are necessary for optimal production plans in structurally controlled prolific basins around the globe.
