摘要
根据地层倾角测井可知崩落椭圆井眼长轴方向,进而确定现代构造应力场最大水平主应力方向,可用于:(1)研究油田区局部应力场和区域应力场的关系;(2)预测人工压裂缝的延伸方向;(3)指导合理地布置油水井网.
Abstract
The stretching direction of artificial compressed fractures could be determined with the aid of principle horizontal stress direction of modern tectonic stress field in oilfield area that was measured in dipmeter logging,and the proper disposal of oil-water well net-work could be made under its guidance.An ideal well network would be that one rank of oil-wells and one rank of water-wells dispose along the principle horizontal stress direction.The oil-wells and water-wells would not be arranged alternatively.
