火焰山地区二叠系梧桐沟组沉积储层研究
|
摘要
继Yb1井获得高产稠油油流之后,火焰山地区掀起了稠油勘探的热潮。研究表明,稠油油藏的富集程度与有利相带分布有明显的正相关关系。针对这一特征,通过应用"定物源—定沉积体系—定有利相带—定有利储层"层层细化的研究方法,首次对研究区的沉积储层进行了系统研究,落实了沉积体系的发育情况,并采用BP、SPR方法,开展了重点目标区储层预测工作,落实2个井位目标均获得成功,应用效果显著。同时指出了下一步的勘探方向,对火焰山地区的稠油勘探具有重要意义。
High industrial production of heavy-oil in Well Yb1 leads to a heavy-oil exploration boom in Huoyanshan. Research indicates that there is a positive relation between the enrichment level of heavy-oil reservoir and favorable facies distribution. Considering this understanding,the gradual refinement of"definite provenance-definite sedimentary system-definite favorable facies-definite reservoir"is used to systematically research the sedimentary reservoir for the first time and identify the development of sedimentary systems. BP and SPR methods are used to predict the reservoirs in major target areas. Two well positions with favorable application are successfully placed,which also points out the further exploration trend and is of great significance to the heavy-oil exploration in Huoyanshan.
