摘要
中国石化于2001年开始从事海外油气勘探开发业务,经过近10年的努力,截至2009年底在20个国家拥有33个勘探开发项目,权益油产量超过千万吨。由于中国石化进入海外勘探开发市场相对较晚等原因,目前海外所辖勘探区块大多位于海域、沙漠、沼泽和山地等地表条件相对较差的地区,很多区块处在含巨厚盐层的盆地,或中深层超高压区域。因此对石油工程技术提出了5项需求:1)不同地面环境对钻机的需求;2)应对复杂地质条件的钻井完井技术;3)定向钻井技术是海外勘探开发的重要技术;4)提高固井质量;5)科学合理地确定探井的井身结构。最后分析了中国石化海外勘探的发展趋势,并提出只有开展技术创新,形成具有国际竞争力和自主知识产权的核心工程技术,才能实现油气勘探的重大发现和突破,迅速增加油气储量。
Sinopec entered the upstream market of overseas oil and gas explorations in 2001.After 10 years of hard work,now in 20 countries with 33 exploration and development projects,the production of oil equivalent is more than 10 million tons.Sinopec entered the overseas market relatively late,and most of the current overseas exploration blocks are located in offshore,deserts,swamps and mountains and other areas with relatively poor surface conditions.Some blocks are in basins with thick salt layers or in areas with high pressure in middle or deep formation.Therefore,petroleum engineering technology put forward five requirements： 1） effect of surface condition on the demand of drilling rigs;2） technology for complex geological conditions;3） directional drilling which is a key technique for overseas exploration and development;4） improving the quality of well cementing;5） reasonable well design.This paper analyzed Sinopec’s overseas development trend and pointed out that only through technique innovation to develop the key engineering technique with own independent intellectual property rights,the major discovery of oil and gas exploration can be achieved and oil and gas reserves can be increased rapidly.
