摘要: 针对海塔油田下部地层复杂情况和地层机械钻速低等问题,通过分析实际钻井资料,利用通用钻速方程得出海塔油田地层岩石可钻性级值规律,并绘制出地层岩石可钻性与地层深度剖面图。该项研究为海塔油田科学制定钻井工程设计提供了科学依据。Abstract: Aiming at the problems such as complicated formation of the lower part and low ROP,through the actual drilling data analysis,by using drilling speed equation,the drillabili-ty regularity will be reached and then the mapping of rock drillability and formation depth profile could be drawn,which will provide scientific basis for drilling engineering de-sign of Haita oilfield.
