摘要
针对川口油田长4+5层注水水淹方向比较多、人工裂缝是水平缝还是垂直缝一直存在争议的情况,通过对岩芯地应力、天然裂缝、岩性平面非均质性、岩石抗张强度等的综合分析,得出该区的人工裂缝主要为垂直缝,垂直裂缝可在各个方位分布,但以东西向为主,这一认识得到了地面微地震、大地电位法监测结果及生产动态资料分析的证实。
The characteristic of the hydraulic fractures of Chuankou Oilfield is still in debate. Through comprehensive analysis on the geostress, natural fractures, sedimentary facies and tensile strength of rock, it is found that the hydraulic fractures are mostly vertical, and they orient mainly in east-west direction. This result is supported by production analysis and geophysical monitoring.
