钻孔漏失是钻探中不好解决的难题,长期以来,人们已从多方面开展研究试验堵漏方法与工艺,虽已取得了很好的成绩,但复杂层的漏失问题,仍是生产中的拦路虎,它直接影响着钻探的施工进度,经济效益以及地质效果. 为解决此难题,福建省煤田地质勘探公司、冶金地质勘探公司先后与泉州腐植酸厂组织协作,开展研究试验高吸水性树脂(PAN-HAK)堵漏剂,并取得良好效果.该项新工艺与配方与往日所用的堵漏剂不同,它是依靠新的化学膨胀材料来达到堵漏目的的,而过去堵漏技术多是依靠化学速凝材料或是固体惰性材料进行的.
Drilling loss is difficult to solve the problem of drilling, for a long time, people have carried out studies from various aspects of plugging methods and techniques, although has made good achievements, but the loss of complex layers, is still in production Stumbling block Tiger, it directly affects the drilling progress, economic benefits and geological effects.In order to solve this problem, coalfield geological exploration company in Fujian Province, metallurgical geological exploration company has cooperation with the Quanzhou humic acid plant organizations to carry out research and testing superabsorbent resin ( PAN-HAK) plugging agent, and achieved good results. The new technology and formula used in the past, the plugging agent is different, it relies on the new chemical swelling materials to achieve the purpose of plugging, plugging technology in the past and more Rely on the chemical fast-curing material or solid inert material.
