测斜事故指卡埋仪器和断脱缆绳事故如处理不好，有可能报废缆绳和仪器。一、测斜事故发生的原因1．钻孔孔壁不稳定，掉块、坍塌造成卡埋仪器事故。2．泥浆质量差，泥皮厚而疏松，仪器与孔壁间隙小，产生刮削泥皮，造成卡塞仪器事故。3．套管断脱后错位或有残留钻具，仪器提升时受阻。4．仪器经过倾斜钻孔的超径孔段或空洞时，偏离钻孔轴线而靠于下侧，造成提升困难。
Inclinometer accident refers to the buried instruments and broken cable accident if not handled properly, it is possible to scrap the cables and equipment. First, the inclinometer accident causes 1. Drilling holes wall instability, dropped pieces, collapse caused by card buried instrument accident. 2. Mud poor quality, mud thick and loose, small gap between the instrument and the hole wall, resulting in scraping mud, causing jam instrument accident. 3. Dislocation of the casing after dislocation or residual drilling tools, instrument lifting blocked. 4. When the instrument passes through the oversize hole section or hole with oblique drilling, it deviates from the axis of the hole and leans to the lower side, which makes it difficult to lift.
