中国石油大港油田历经50多年的勘探开发,油气勘探面临着:勘探层系由浅层向深层转移,勘探领域由常规砂岩油藏向非常规油藏转移;深层储层物性差,储层非均质性强,识别困难;非常规领域勘探开发难度大。在低油价形势下,实现效益增储困难重重。为此大港油田在开展勘探成本控制因素分析、明确成本主控因素的基础上,通过精细井位部署和优化设计、精细施工过程控制,有效控制了勘探的成本和质量,保证控投降
After more than 50 years of exploration and development, China National Petroleum Dagang Oilfield faces the following problems: the exploration strata transfer from shallow to deep, and the exploration area is shifted from conventional sandstone reservoirs to unconventional reservoirs; the deep reservoir properties are poor, Strong quality, identification difficulties; unconventional exploration and development difficult. In the situation of low oil prices, it is very difficult to realize the increase of profits. To this end Dagang Oilfield in carrying out exploration cost control factor analysis, based on a clear cost control factors, through the fine well deployment and optimization design, fine construction process control, effective control of the cost and quality of exploration to ensure the control surrender
