摘要
沙市油田是低渗透断块油藏,储层含伊利石、蒙脱石等敏感性矿物,储层物性差、孔吼半径小、地层压力低,前期措施液体系对该区存在一定程度的伤害。以提高该油田产量为目的,通过对敏感性储层保护机理再分析,采用新型增产工艺技术系列,有效避免措施液体系对储层的伤害,为敏感性油藏的增产技术提供参考和借鉴。
Sangshi Oilfield features low-permeability fractured reservoirs with sensitive minerals like illite and montmorillonite,characterized by poor reservoir properties,small pore-throat radius,and low formation pressure.Previous fracturing jobs using liquid systems have caused some degree of damage to the area.To enhance oil production,a series of new stimulation techniques were applied after reanalyzing the protection mechanisms for sensitive reservoirs,effectively avoiding damage caused by liquid systems and providing references for increasing production in sensitive reservoirs.
