在南得克萨斯高温井况下获得井口和地层数据往往受限于随钻测量 (MWD)和随钻测井 (LWD)在恶劣井口环境中的应用。在最近的两次开采实例中 ,Newfield勘探公司针对MWD和LWD技术的局限性进行了卓有成效的改进 ,在前所未有的极限温度下获得了高质量数据。MWD和LWD技术水平对钻井操作具有深远的影响 ,尤其在许多高温井的应用中影响更不能忽视。在本文提及的 2口井中 ,通过以下措施提高了高温操作和测井的经济性 :低成本侧钻 ;不使用衬管 ;可以获得产油气带的高质量测井数据 ;缩短了测井时间 ;测井时提高了井控能力 ,降低了风险。在高温条件下钻井和测井可使难采井得到更有效的钻进和完井 ,从而可以降低总成本和提高勘探开发的能力。
Getting wellhead and formation data at high Texas temperature well conditions is often limited by MWD and LWD applications in harsh wellhead environments. In the most recent two mining examples, Newfield Exploration Inc. has made significant improvements to the limitations of MWD and LWD technology, with high-quality data at unprecedented ultimate temperatures. The MWD and LWD technologies have far-reaching implications for drilling operations, especially in many high-temperature wells. In the two wells mentioned in this paper, high-temperature operation and log economy are enhanced by: low-cost sidetracking; non-use of liner tubes; high-quality log data from oil and gas producing zones; shortening of logging time Logging improves well control and reduces risk. Drilling and logging at high temperatures allows harder wells to be drilled and completed more efficiently, reducing overall costs and improving exploration and development capabilities.
