浅谈河南油田低渗储层深抽排采工艺应用OA

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 a-chieving efficient exploration and development of deep formations.
