摘　　要：从油源、构造、沉积、储层等方面对清水区块清22深层圈闭进行了研究，并用Gxii反演模型对目标区储层作了定量预测。根据邻井对比，储层预测及断层封堵性研究，认为清22北断层及大洼断层都是封堵的，因此圈闭是有效的，对清22深层圈闭进行油藏模拟，并以确切井数建立生产模式，对投资规模及回报率进行分析，证明该圈闭具有开采价值，预测可采地质储量为500－800万t，获得该可采地质储量的成功率为36％－48％，以水平井方式生产最为有利。This paper studied Qing 22 deep prospect of Qingshui Block in respect of source rock evaluation,structure, sedimentation and reservoir etc,and quantitative prediction was made to the objective reservoir by using Gxii reversion modeling. According to offset wells correlation,reservoir prediction and fault seal study, it was considered that the northern fault and Dawa fault of Qing 22 was sealed,so the prospect is effective. Through reservoir simulation of Qing 22 prospect the production mode was established with definite numbers of wells and the investment scales and return rate was analyzed,so the prospect was proved to be valuable to have 5-8 million tons of recoverable geological reserve, the success rate being 48%. Horizontal drilling is the most favorable producing method.
