| 中文摘要:裂隙的数量和尺寸会影响油页岩原位开采的成本与效率，开采前需对油页岩进行水力压裂来建立或扩展裂隙,而压裂过程中的破裂压力是一个重要的参数。以农安矿区油页岩为研究对象，数值计算了其射孔完井下的水力压裂的破裂压力并采用真实破裂过程分析软件（二维渗流分析版）对水力压裂过程进行数值模拟，得到油页岩破裂压力。同时对该矿区油页岩压裂进行了实验对比，验证了数值模拟的有效性。对比结果表明模拟值、实验值较计算值均偏大。 |

| Abstract:The cost and efficiency of in-situ mining of oil shale are affected by the number and size of cracks, it is necessary to build or expand fissures before hydraulic fracturing of oil shale and the fracturing pressure is an important parameter in the fracturing process. This paper takes the Nong’an oil shale as the research object, the numerical calculation of fracturing process of hydraulic fracturing process under perforation completion and numerical simulation was made on hydraulic fracturing process with 2D seepage analysis version of realistic fracturing process analysis software; the fracture pressure of oil shale was obtained. The experimental comparison was carried out on oil shale fracturing in Nong’an mining area; the validity of the numerical simulation was verified. The comparison results show that both the simulation and the experimental values are larger than the calculated ones. |
