摘要:
吉木萨尔凹陷致密油藏储量巨大,但储集层孔渗性差,其单井产量低、生产周期长、开发成本高,系统地研究储集层岩石物理力学和地应力特征,对致密油藏的勘探开发有着重要意义。为了认识致密油藏储集层的岩石力学特征,建立储集层岩石力学参数测井评价模型,优化工程技术措施,选取吉A井和吉B井全直径岩心,在围压分别为0.689 5 MPa,11.032 0 MPa,22.064 0 MPa 下进行声波测试和三轴抗压测试。结果表明,纵波和横波速度、动静态杨氏模量相互关系显著,三轴抗压强度随围压增大近似线性增大,围压对样品的破坏形态具有显著影响。
Abstract:
Tight oil reservoir in Jimusaer sag of Junggar basin is characterized by huge reserves, poor porosity and permeability, low singlewell production, long production cycle, and high development cost. Systematic study of its petrophysical mechanics and ground stress characteristics have become the key of the tight oil reservoir exploration and development. For this reason, this paper developed the logging evaluation model of the petrophysical mechanics parameters, optimized the measures of engineering technology, selected whole diameter cores of Ji?A and Ji?B wells, and conducted acoustic wave and triaxial compression experiments under three confining pressures of 0.689 5 MPa, 11.032 0 MPa and 22.064 0 MPa. The results show that there exists obvious correlation between longitudinal?shear wave velocity and dynamic?static Young’s modulus; the triaxial compression strength is linearly increasing with the confining pressure increase, and the confinning pressure has a significant effect on compressive failure of specimen
