摘要/Abstract

摘要： 针对南美前陆盆地斜坡带圈闭规模小、热带雨林地貌勘探投资大、丛式平台优选难的问题，以厄瓜多尔奥连特盆地TW区块为例，在圈闭地质风险评价后，进行平台控圈闭群经济性评价，最终实现丛式平台优选评价。评价方法流程包括：1）圈闭地质风险评估和圈闭资源量评价（传统六要素评价）；2）丛式平台经济评价，设计N个平台（每个平台控制圈闭不同），对单一平台控制范围内的圈闭进行经济性评价，包括投资（钻井、平台建设、道路及管线建设、射孔费用、地表植被复原费等）和收益（原油出售），剔除没有经济价值的圈闭后重新对单一圈闭的经济性进行评价，直至单一平台内所有圈闭均具有经济价值；3）丛式平台和圈闭优选：根据单一平台控制圈闭总经济价值大小，优选出最优的丛式平台，按照经济价值大小对最优平台控制圈闭进行优选获得圈闭排序；4）新一轮平台和圈闭优选，删除已选出的圈闭后重新进行步骤2）—3），最终获得研究区的平台及圈闭优选排序。运用该方法提出TW区块平台建设和圈闭钻探建议，实施效果良好。

Abstract: Due to small trap size and big exploration investment on tropical rain forest, platform and trap optimization in slop belt of South America foreland basin has become a big problem that should be faced by geologist. Taking the TW block in Oriente basin, Ecuador as an example, the paper introduced cluster platform economic assessment after trap geological risk analysis, and realized cluster optimization. The evaluation process is as follows. 1) Trap geological risk analysis and resource assessment (traditional six factors assessment). 2) Platform economic assessment:design N platforms (different traps in different platforms), do economic assessment of each trap within the same platform, including investment (e.g. well drilling, platform construction, road and pipeline construction, perforation, surface recovery etc.) and income, and get rid of the trap with profit smaller than 0, and re-evaluate each trap till all the traps' profits are larger than 0. 3) Platform and trap optimization:optimize platform according to total profit of all the traps, then sequence the trap by profit controlled by the optimized platform. 4) New round platform and trap optimization:get rid of the optimized traps and go to step 2) and 3) till all the platform with profit larger than 0 has been selected. The new method has been used in platform and trap optimization in TW block which shows good result in practice.
