摘要(Abstract)：

水平井地质导向技术首先根据周边完钻井资料建立地质模型,利用水平井随钻测井资料与周围控制井信息进行储层预测。钻井过程中,在构建的地质模型基础上,根据LWD不同测井系列的数据和综合录井资料,实时验证地质模型的构造和储层信息,及时校正地质模型,对靶点深度进行实时预测,及时调整靶点,实现优化水平井轨迹的目的。苏德尔特油田采用水平井开发潜山油藏,在水平井钻井过程中,根据目的层油藏类型和构造、储集层特征,确定了水平井着陆和水平段钻进的导向原则,保证了水平井精确中靶并使水平段最大限度地穿越潜山有效储集层,与传统导向技术相比,大幅度提高了水平井钻井成功率
For the geosteering technique of horizontal well,at first make geological model according to the completion and drilling data of the peripheral region and then with the help of measuring-while-drilling(MWD) data and the information of adjacent controlling wells carry out reservoir prediction.In the course of drilling,on the basis of the built geological model,by means of data of both LWD different well logging series and comprehensive mud logging,real-time verify the structure of the geological model and the information of the reservoirs,correct in time the above model and realtime predict the depth of target point.Finally adjust the above point punctually so as to realize the aim of optimize the trajectory of the horizontal well.In Sude'erte Oilfield,the buried hill oil reservoir is developed by horizontal well.In the course of the above well drilling,according to the type and structure of target oil layer and furthertmore the characteristics of oil reservoirs,the steering principle of well landing and horizontal interval drilling has been determined,so the target can be accuratelv penetrated and the effective reservoir of the buried hill can be crossed to maximum degree. Comparing with the conventional steering technique,the success rate of horizontal well drilling has been greatly increased.
