3月14日,海洋工程公司应用抗盐聚合物钻井液体系顺利完成埕海43井的施工,完井电测一次到底,应用效果显著。该井由中油海1平台承钻,是一口二开制预探直井,设计井深2 890 m,完钻井深2 782 m。该井钻遇地层多,同一裸眼段分别钻遇明化镇组、馆陶组、东营组和沙河街组,进中生界完钻。地层岩性复杂,上部地层易漏失、下部地层易坍塌。 March 14, the offshore engineering company application of salt-resistant polymer drilling fluid system successfully completed the construction of Qionghai 43 wells, completion of electrical measurements in the end, the application of significant results. The well drilled by the platform of Zhongyouhai 1 is a pre-exploration vertical well with a designed depth of 2,890 m and a drilling depth of 2,782 m. The well drilled encountered many strata, and the same naked eye segment was drilled to the Minghua, Guantao, Dongying and Shahejie formations, respectively. Stratigraphic lithology is complex, the upper formation easily lost, the lower formation collapses easily.
