青西油田属深层裂缝性复杂油气藏 ,由于对油气的控制因素、分布规律、生产规律、富集规律认识不清 ,加上该油藏埋深大、钻井成本高 ,所以勘探风险很大。为了提高勘探效益及了解复杂油藏的控制因素 ,应用油藏描述的方法来认识油藏的类型和油气控制因素 ,应用三维地震资料精细解释、成像测井、地震相干数据体预测裂隙发育带 ,用地震多参数识别的方法 ,确定油藏平面分布规律和高产区。通过以上技术攻关 ,对油气富集及分布规律有了明确认识 ,获得了良好的经济效益
Qingxi Oilfield is a deep fractured complex reservoir. Due to its unclear understanding of the control factors, distribution laws, production rules and enrichment laws of oil and gas, as well as the high buried depth and high drilling cost, Qingxi Oilfield poses a great risk of exploration. In order to improve the exploration efficiency and understand the control factors of complex reservoirs, reservoir description methods are used to understand the types of reservoirs and hydrocarbon control factors. Three-dimensional seismic data interpretation, imaging logging and seismic coherence data are used to predict fracture development zones. Using seismic multi-parameter identification method to determine the plane distribution law and high-yielding area. Through the above technical breakthroughs, a clear understanding of the laws of enrichment and distribution of oil and gas has obtained good economic benefits
