地震与测井资料在塔河工区钻井中应用

THE APPLICATION OF THE SEISMIC AND LOG DATA IN THE DRILLING OPERATION OF TAHE OILFIELD

塔里木盆地钻井施工中 ,由于井深、井距大、参考资料少、钻井设计的盲目性大、造成钻井施工周期较长。本文以地震层速度及测井资料为基础 ,建立了一套快速认识钻井地质环境因素的方法 ,并在塔河工区进行了应用。该方法能快速优选钻头类型 ,使地层孔隙压力的计算与实测误差小于 10 %。因此 ,本方法应用能满足探井和开发井钻井工程需要。

During the drilling operation in the Tarim basin,because of the lack of information,deep depth and large well spacing,the drilling design is with great blindness which results in the long operation period.The article establishes a set of methods to recognize the drilling geology environment factors on the basis of seismic layer-velocity and log data,and which have been applied in the Tahe operation zone.The method could let us to select the drilling bit rapidly and make the deviation between the porosity pressure calculation and the real measure less than 10%.So,the application of the method could meet the need of drilling engineering of exploration well and development well.
