增能吞吐技术在马西油田的应用

Application of Energizing and Huffing Technology in Maxi Oilfield

马西油田作为低孔低渗开发单元,存在注水压力高注水难的问题,地层能量得不到补充,老井产量不断下降,为此,技术人员以区块为研究对象,将压裂、增能、驱替和渗析采油相结合,形成了增能吞吐新技术。通过该技术在马西油田的试验应用,在形成裂缝补充地层能量的同时,大大提高了开发单元的驱油效率和井组产量,为低孔低渗油藏开发提供了新方向。

As a low-porosity and low-permeability development unit, the Maxi Oilfield has the problem of high water injection pressure and high water injection. The formation energy is not supplemented, and the output of the old wells is decreasing. For this reason, the technicians will use the block as the research object and will fracturing. The combination of energy-enhancing, displacement and dialysis oil production has formed a new technology for energy absorption and throughput. Through the application of this technology in the Maxi Oilfield, while forming the fracture to supplement the formation energy, the oil displacement efficiency and well group production of the development unit are greatly improved, which provides a new direction for the development of low porosity and low permeability reservoirs.
