国产旋转导向及随钻测井系统在渤海某油田的应用

Application of China-made Rotary Steering and Logging while Drilling Systems in Adjustment Well of Bohai

摘要:

旋转导向和随钻测井系统可在精确、高效控制井眼轨迹和快速识别地层性质的同时大幅度提高作业效率，降低作业成本。尤其在海上油气开发过程中具有较好的提效效果，但是长期以来该领域均被国外石油公司垄断且租赁价格高昂。中海油国产化研制的Welleader旋转导向系统、Drilog随钻测井系统经过多次试验达到了入井应用要求，在渤海某平台调整井钻井作业中进行了应用，结果表明该套系统旋转导向系统轨迹控制满足定向井轨迹要求、测斜数据准确、测井质量符合标准要求，能够实现钻井过程中的轨迹控制和测井要求。

Abstract:

The rotary steering and the logging while drilling systems can effectively control the well trajectory and quickly identify the formation property, which can greatly improve the operation efficiency and reduce the operation cost, especially in offshore oil and gas development; but this field has been monopolized by foreign oil companies with high rental prices for a long time. Welleader rotary steering system and Drilog logging while drilling system developed by CNOOC have been tested for times and up to application requirements. These systems were used in an adjustment well drilling on a platform in Bohai, the application results prove that the trajectory control of rotary steering system can satisfy the directional well trajectory requirements; the accuracy of the measured data and the quality of the well logging are in line with the standard requirements, by which the trajectory control and logging are realized in drilling process.
