摘要: 针对南泥湾油田三叠系延长组长6组油层段压裂产生何种裂缝形态问题,笔者以微震监测技术为基础,对该油田具有代表性6口油井进行实验,结果显示,油层埋藏深度650.0m～797.0m为垂直裂缝;349.0m～383.0m为水平裂缝。形成垂直裂缝的延伸长度为138.0m～149.3m,最大裂缝方位为108.9°,最小裂缝方位为58.0°;形成水平裂缝的延伸长度为99.1～117.4m,最大裂缝方位99.2°,最小裂缝方位为76.6°。Abstract: Based on micro-quake suspecting technology,the authors studied what the shape fracturing may made in the Chang-6 layer of Triassic system of Nannwan oilfield,and took experiments on six particular oil well of Nanniwan oilfield.The results show that the fracture is vertical at the buried depth between 650.0 m and 797.0 m and the fracture is horizontal at the buried depth between 349.0 m and 383.0 m.The extension of the vertical fracture is 138.0～149.3 m,the largest fracture direction is 108.9°,and the least one is 58.0°.The extension of the horizontal fracture is 99.1～117.4m,and the smallest fracture direction is 76.6°.
