摘要
针对延长气田的勘探开发现状,马家沟组中组合的探索认知由于岩心资料不足等客观原因,只能通过测井资料及录井资料来判断识别储层,Y802-1井的中下组合试气取得突破,确定了马家沟组中下组合勘探开发的巨大潜力。综合前人认识研究及文献调研,结合区域构造、小层厚度、电性特征及录井气测解释评价,对W区域马五段马五7小层进行储层特征研究,并预测了有利储层发育的平面分布。
In view of the present situation of exploration and development in Yanchang gas field,the exploration cognition of the assemblage in Majiagou Formation is due to objective reasons such as insufficient core data.Reservoir identification can only be judged by logging data and mud logging data. A breakthrough has been made in gas testing of Y802-1 well.The great potential of exploration and development of the lower and middle assemblages of Majiagou Formation is determined.Based on previous research and literature review,combined with regional structure,small layer thickness,electrical characteristics and interpretation and evaluation of mud logging gas logging,Reservoir characteristics of Mawu 7 formation in W region are studied,and the planar distribution of favorable reservoir development is predicted.
