摘要
埕岛油田位于渤海西南部极浅-浅海地区,是一个大型潜山披覆构造油田.迄今共完成各类探井68口,获油气层井67口,获工业油流井55口,探明含油面积123.6km2、石油地质储量34486.0万t.埕岛油田为典型复式油气聚集带,已发现7套含油层系,10多种油藏类型.在该油田浅层(明化镇组、馆陶组上段)勘探开发中,采用科学的勘探开发程序,以及8项勘探开发配套技术,取得了良好的勘探开发效果.探井成功率达98.5%;探井见工业油流率达80.9%;每打一口探井平均获探明石油地质储量507.2万t;每获一吨探明石油地质储量直接投入为4.48元.按照"简单、经济、安全、可靠,还要重视环保”的原则,进行海工工程和油气集输流程的建设,已建成216万t年产能力,累计生产原油800多万t.
Chengdao oilfield,located in an extremely shallow-shallow offshore area of the southwestern Bohai, is a large drape structure over buried hills. So far 68 various exploratory wells have been completed,in which 67 have oil and gas reservoires and 55 have commercial oil flows,resulting in 123. 6km2 of proved oil- bear-ing area and 344. 86 million tons of geologic oil reserves. The Chengdao area is a typical belt of composite hydrocarbon accumulation,where 7 series of oil-bearing strata and more than 10 types of oil pool have been found. For the shallow (Minghuazhen Formation and Upper Member of Guantao Formation)exploratory development in the field,a scientific program and & supporting techniques are used,leading to an excellent operation efficiency. For example,the success ratio of exploratory wells is 98. 5 % and the commercial flowing ratio is 80. 9%,with geologic reserves per exploratory well averaging 5. 072 million tons and direct investment per ton of geologic reserves about 4. 48. Based on a 'simple, economic,safe,reliable and environmentalist 'principle,the field's offshore engineering and collection system of oil and gas are constructed, building an annual production capacity of 2. 16 million tons and cumulatively producing oil over 8 million tons.
