中新网大庆8月6日电 (余虹娜 邱忠媛)6日,记者从大庆钻探获悉,在山东泰安肥城盐穴储气库TAKY1井,大庆钻探西部钻井分公司成功突破“地质禁区”,实现连续取芯284米;岩芯收获率高达99.5%,远超行业平均水平;平均机械钻速6.49米/小时;取芯周期仅9.62天,较设计工期提前15天以上。

泰安储气库是国家能源战略重点项目,此次取芯,目的层为盐岩、膏盐岩与泥灰岩互层,累计盐岩厚度131米,单层厚度2.5米至15米。盐岩软脆易碎,遇水即溶;膏盐遇水膨胀,堵心、磨心说来就来;泥灰岩硬度高、研磨性强。
面对这尖端的难题,工程技术研究院迎难而上,依托多年技术积淀,自主研发DQM180-115双节取芯工具,并配套特制8刀翼底喷水眼式取芯钻头和DSM油基保护液工艺,形成了一套专克盐膏层的“组合拳”——双筒单动结构极大减少了钻具旋转对岩芯的机械扰动;保护液如同一道“隐形防护膜”,将钻井液与盐膏岩彻底隔离,从源头掐断溶蚀、膨胀的链条。
此次成功突破“地质禁区”,验证了大庆钻探工程技术研究院自主研发的盐膏层取芯工具的良好适配性。(完)
