5月14日，由渤海鉆探定向井公司提供技術(shù)服務(wù)的FY304-H2井于近日順利完鉆。完鉆井深8322米，垂深8069.71米，刷新國(guó)內(nèi)8000米以上深井超深井鉆井周期最短紀(jì)錄！
FY304-H2井是塔里木油田部署在塔里木盆地北部坳陷阿滿過渡帶FI16斷裂帶南段的一口重點(diǎn)水平井。
開鉆前施工小組和相關(guān)方充分溝通，預(yù)判全井技術(shù)難點(diǎn)，根據(jù)井底靜止溫度，選擇適宜的抗高溫螺桿和儀器。鉆進(jìn)過程中，施工小組與鉆井方密切配合，動(dòng)態(tài)調(diào)整最優(yōu)鉆壓和轉(zhuǎn)速，有效規(guī)避卡鉆風(fēng)險(xiǎn)，確保動(dòng)力鉆具在平衡狀態(tài)下高速工作。施工過程中嚴(yán)格執(zhí)行中途循環(huán)降溫措施，以保證儀器穩(wěn)定工作。以多項(xiàng)有力舉措助力這口井刷新國(guó)內(nèi)8000米以上深井超深井鉆井周期最短紀(jì)錄。
