钻井液是钻井中的血液。故钻井时是否优化配置符合该地区的钻井液,是影响钻井的平均机械钻速快慢、建井周期长短、井身质量合格与否等一系列评价钻井的重要因素。该地区所钻的井都属于区块探井,所以做好油气层保护也是一个重点。由于柴达木盆地西部小梁山地区的地质状况方面是个盲点,所以在该地区刚开始钻井时钻井液的配置方面是用“摸着石头过河、边钻边寻、不断总结经验”的方法进行的。直至钻了几口井之后基本掌握了该地区的岩性分布情况后,在钻井液优化配置才有了比较容易的控制,为该地区的勘探任务取得了较好的成绩。
Drilling fluid is the blood in the well. Therefore, it is an important factor to evaluate a series of drilling wells that whether drilling fluid optimized in drilling is in accordance with the drilling fluid in the area is affecting the average drilling speed, the length of drilling well and the quality of well bore. All the wells drilled in this area belong to block exploration wells, so it is also a key point to protect the reservoirs. Since the geological conditions in the Xiaoliangshan area in western Qaidam basin are a blind spot, the deployment of drilling fluid in the area just started drilling is based on the experience of crossing the river with stones Method carried out. After drilling a few wells and basically grasping the lithology distribution in the area, it is easier to control the optimal configuration of drilling fluid and obtain better results for exploration tasks in the area.
