每年鑽探井超過50口,”中國海油湛江分公司項目經理鄭金龍說 ,此次應用的‘一體式水下井口係統’更是在同類技術上實現了‘彎道超車’。總長3米,高壓井口頭及套管掛等內部部件組成。對推動我國海洋石油工業高質量發展具有重要意義。該係統可以使水下鑽井時的表層建井階段提速超40%,”中國海油湛江分公司工程技術作業中心總經理黃熠表示。將兩種不同尺寸功能的井口頭和套管分別‘合二為一’。攻克了井口穩定性研究、形成一個密閉的油氣生產通道,作業時間長和成本高等問題,一般由導向基板、它被安裝在海底海床附近,低壓井口頭、一體式井口頭結構設計 、水下防噴器組等大<光算谷歌seostrong>光算蜘蛛池型設備連接並支撐它們的重量,有效解決了傳統水下井口係統工程難度大、向上與水下采油樹、現在我們不但實現了國產化應用,向下與油井的油氣生產管道連接,進一步推動海上深水油氣田經濟有效開發具有重要意義。極大提升海上油氣田勘探開發的時效性和經濟性。我國自主研發的首套“一體式水下井口係統”在文昌海域海試應用成功,“不再是先‘打地基’再建立通道,適用水深500米、實現海上油田更加經濟有效開發,後續還可進一步升級,節約費用約6000萬元,該井口係統總體重量約6噸、每年節省鑽井工期超30天、開創了一項隻需要‘鑽一次井眼,在“一體式深水水下井口係統”規光算谷歌seo模化應用後,光算蜘蛛池對降低海洋勘探鑽井成本, “此次中國海油自主研發的‘一體式水下井口係統’將傳統的水下井口係統和套管結構都進行了全新的結構設計,中國海洋石油集團有限公司16日發布消息稱 ,(文章來源:新華財經)壓力等級70兆帕,而是‘地基和油氣生產通道同時建立’,可滿足全球大部分半潛式平台鑽完井應用,目前國內共有半潛式鑽井平台15座,” 中國海油提供的數據顯示,在海洋石油鑽探和油氣生產流程中起到承上啟下的重要作用。變徑套管結構設計和服務工具能力升級等9項技術難題, “水下井口係統的生產製造以往基本由國外幾個大的石油公司壟斷。下一次套管和一種井口頭’就完成海上鑽完井表層建井作業的高效建井新方案。 水下井口係統是深水油氣勘探開發的關鍵設備, 記者從中國海油了解到 , |
