摘　　要：在破碎地层取心钻进过程中,经常出现堵心和卡心等情况,如果判断不及时就会出现丢心和磨心,丢失一些原始资料。为正确分析地下岩层岩性和储层特性带来的困难,研制了岩心解堵和报警装置,为正确判断井下情况和取全、取准资料带来了方便,并在吉林油田红75-1等井进行了试验,取得理想的效果。During the coring in the cracked stratum, coring jam and stick happen very often. And if the technicians can＇t make judgment for it in time, the core will be ground and the original pa- rameter will be lost. Then it will be difficult to analyze the lithology of the terrane and the reser-voir. So the alarming and rescinding devices for coring jam is developed. These devices are very convenient to judge the downhole situation correctly and keep the core integrated, and they had been tested successfully in Hong 75-1 of JiLin oil field.
