随着国家对石油能源的需求量不断增加,有效提升低渗油田的采收率便成为石油行业当前需要急切解决的问题。由于我国的低渗透油藏地的地质条件较为复杂,对于此类油田的开采技术方面存在较大的差异性。为了能够有效提升低渗透油藏地原油的开采率,笔者将分析低渗透油田开采中面临的主要矛盾与技术难点,并以金龙3井区为例分析论述有效开发低渗透油田的技术方案。
As the country’s demand for petroleum energy continues to increase, the effective recovery of oil recovery from low-permeability fields has become an urgent issue for the oil industry. Due to the complicated geological conditions in the low-permeability reservoirs of our country, there are great differences in the mining technologies for such fields. In order to effectively improve the recovery rate of crude oil in low-permeability reservoirs, the author will analyze the main contradictions and technical difficulties in the exploitation of low-permeability oilfields. The technical solution of effectively developing low-permeability oilfields will be discussed with the example of Jinlong 3 well.
