随着濮城油田进入老油田开发阶段,地下认识、措施挖潜、油藏经营等各项工作都为我们提出了更高的要求。濮城油田地质构造复杂,有盐层发育、井深、高温、高盐、高压及高矿化度等特点。在油田开发过程中,压裂、补孔、高压注水等油田增产措施的实施,客观上加剧了油水井套管损坏,形成了大量的复杂事故井。 As Pucheng Oilfield enters the stage of development of old oilfields, all kinds of work such as underground understanding, measures to tap the potential and reservoir management have put forward higher requirements for us. Pucheng oilfield geological structure is complex, with salt development, well depth, high temperature, high salt, high pressure and high salinity and so on. In the process of oilfield development, the implementation of oilfield stimulation measures such as fracturing, backfilling and high pressure water injection objectively aggravated the casing damage of oil and water wells and formed a large number of complex accident wells.
