摘要
北部湾盆地的碳酸盐岩古潜山油藏具有裂缝发育、地层压力低、含油性好及产量高等特点。根据初步钻探实践认为:探井井位的选定应沿长轴、占高点、找扭曲;先期套管完井,采用优质轻泥浆钻开油层;综合各种录井资料判断油气层,分段测试确定油水界面;在测试时宜用大功率电潜泵排压力液,以保证测试资料的可信度和提高时效。这些主要措施的改进,将会提高在海上钻探这类油藏的效益。
Carbonate buried hill rservoirs in Beibu Gulf basin has characteristics of fissure development,lower pressure of formation, high petroliferous and productivity.According to preliminary exploration, the position of well should be located at macroaxis,high position and contortion.Reservoir is drilled with light-weight mud after caseing completion.The judgment of oil & gas layer stem from comprehending loging data.oil-water contact is determined by testing in interval.During testing electric submersible pump with big power was used to deliver pressure liquid,to assure credibility of test data and improve time effect.The improvement of the main measures will increase the benefit of offshore explorating the reservoirs.
