摘要
各向异性地层理论指出,地层的自然造斜能力是由地层的各向异性特性引起的。本文论述了地层各向异性对井眼轨迹的影响,叙述了评价各向异性指数h的计算方法,并编制了求解h值的计算机软件。中原油田是典型的断块油田,不同断块、不同层位地层的h值均不相同,运用编制的计算机软件对中原油田五大构造部分典型断块地层的h值进行计算,对分析评价中原油田不同断块地层的自然造斜能力具有很大的实用价值。
The theory of anisotropic formations shows that the natural deviation deponds on anisotropic character. This paper describes the effect on the well path by anisotropic strata. The computer programme and the calculation method about anisotropic exponent 'h' are also given out. The value of the 'h' varies with the fault blocks and the strata. The 'h' value of five fault blocks in Zhong yuan Oilfield has been calculated by using this computer programme. It has been proved that the ' h' value has an important practicability for evaluating the natural devlated ability of formations.
