摘要
海上油田由于受海水深度和海况限制,钻井和录取资料的成本较高,如何最大限度地优化评价方案,减少钻井、取心和测试工作量,经济有效地加快新油田的评价,一直是海上油田评价的重点。以珠江口盆地新近系中新统NH-AB海相优质砂岩油田评价方案为例,在评价方案优化可行性分析基础上,通过对其评价井井位、井数、取心和测试资料的评价方案优化,可减少钻探评价井2口,只进行1次取心和1次试油,节约成本近亿元人民币,经济有效地加快了NH-AB油田探明石油地质储量的计算和开发评价,提高了海上油田评价的工作效率和经济性,为珠江口盆地该类型油田的快速评价提供借鉴。
Considering the restriction of oceanic condition and water depth in offshore oilfield, and higher cost of drilling and data ac-quiring, the oilfield evaluation is constantly studied to maximize the case evaluation optimization and reduce the time of drilling, coringand testing jobs, and therefore speed up new oilfield evaluation economically and effectively. In this paper, based on example of ma-rine-facies high-quality sandstone from NH-AB oilfield evaluation in Pearl River Mouth Basin of Miocene stratum, and based on feasi-ble analysis of evaluation case optimization, and by means of evaluation optimization on well location and numbers, coring and testing,we successfully reduced two evaluation wells, and only one coring and testing needed, therefore saving about a hundred million RMB ofexploration cost, and accelerating the evaluation jobs and reserve estimation. It can improve the work efficiency and economics of off-shoreoilfieldevaluation, and provide a reference for quick evaluation of similar oilfieldinPearl RiverMouthBasin.
