1.
The common method of measuring drillability was based on interior experiment.
目前确定地层岩石可钻性的方法主要是基于室内微钻头实验测算岩心抗钻能力,这种方法需要大量的岩心,费用高,周期长,且常常滞后于实际钻进。
2.
In view of many problems faced by drilling in the lower stratum in Xujiaweizi region, such as complex geologic structures, high grade value of rock drillability, low drilling rate, slow footage, and long drilling cycle, it is urgent to correctly predict the grade value of rock drillability which will provide powerful references for a better drilling plan in reasonable way.
针对徐家围子地区下部地层的复杂情况,岩石可钻性级值较高,钻井机械钻速低、进尺慢和钻井周期长的问题,迫切需要准确预测徐家围子地区下部地层的岩石可钻性级值,为科学制定钻井计划提供有力依据。
3.
Drillability measurement under modeling conditions of bottom hole stress is very difficult.
模拟井底应力条件测量岩石的可钻性是非常困难的 ,而常压下岩石可钻性与井底围压下岩石可钻性相差较大 ,远不能满足工程需要 ;文章通过室内试验 ,建立了岩石可钻性级值与岩石力学参数的相关模型 ,再把井底围压下的岩石力学参数代入此模型中计算 ,可以得到井底应力条件下的岩石可钻性级值。
