摘　　要：针对河南油田油气勘探程度越来越高,主要目的层深度越来越大,储层物性越来越差,常用机抽排采工艺无法满足高效勘探开发的现状,在调研国内排采工艺技术的基础上,结合河南油田勘探区块的特征,开展适应性分析评价,探索形成了适合河南油田油气藏特点和不同阶段特征的深抽排采技术,可解决深层系探井埋藏深度大、井温高、地层压力系数低、液气比高、排量范围变化大等问题,并建立了一套与不同勘探区块深部储层相适应的深抽排采工艺方案,从而实现深层系的高效勘探开发。In view of the increasing degree of oil and gas exploration in Henan oilfield,the depth of the main target layer is getting deeper,the reservoir properties are getting worse,and the commonly used machine drainage and recovery technology cannot meet the current situation.Based on the investigation of domestic drainage and recovery technology,combined with the characteristics of exploration blocks in Henan Oilfield,the adaptability analysis and evaluation are carried out.The deep drainage and recovery technology suitable for the characteristics of reservoirs and different stages in Henan Oilfield has been explored and formed.It can solve the problems of large burial depth,high well temperature,low formation pressure coefficient,high liquid gas ratio,and large displacement range of deep exploration wells,and establish a set of deep drainage and recovery technology schemes that are suitable for different exploration blocks of deep reservoirs,thus achieving efficient exploration and development of deep formations.
