Research and Application of Large-Scale Fracturing in Block F142

  • 摘要: 为了提高F142区块油藏开发效益,研究并应用了大型压裂开发技术。在充分考虑大型压裂造长缝基础上,综合利用极限井距、经济极限井距和经济合理井距原理,同时结合区块地应力方向,优化了井网井距;在深穿透、造长缝、饱填砂、低伤害和低风险的设计原则上,利用三维压裂优化设计软件,以产量最优为目标,优化了加砂量、排量、砂比和前置液量等参数;根据大型压裂储层、施工时间和施工规模对压裂液性能的要求,优选了压裂液,确定了F142区块低渗透油藏大型压裂开发模式。根据优化结果,F142区块应采用反九点法井网开发,同时采用大砂量、大排量、高前置液量、中等砂比的大型压裂工艺。完成了22井次大型压裂现场试验,平均单井加砂量75 m3;压前平均单井产油量0.8 t/d,压后初期平均单井产油量22 t/d,取得了显著的增产效果。这表明,大型压裂开发技术能够大幅提高F142区块开发效率,为类似储层的高效开发提供了技术借鉴。
    Abstract: In order to improve the development of Block F142 reservoir,large-scale fracturing development technology has been studied.The well pattern and well spacing are optimized by comprehensive utilization of limited well spacing,economic limit well spacing and economic rational well spacing.Based on the design principles of deep penetration,long fracture length,high concentration sand placement,low damage and low risk,treatment parameters such as sand volume,displacement,sand concentration and pad volume are optimized by the 3D fracturing optimization design software(FRACPROPT)for the purpose of optimal production.According to the requirements of formation compatibility,treatment time and scale on fracturing fluid properties,fracturing fluid is selected.Then the large-scale fracturing development mode is determined.Based on the optimization results,reverse 9 spot well pattern should be used for block F142,as well as large-scale hydraulic fracturing featuring"large sand volume,large displacement,large amount of pad fluid,medium sand fluid ratio"(proppant volume: 55-70 m3,displacement: 5.0-6.0 m3/min,ratio of pad fluid to proppant volume: 2.5-3.0,average sand fluid ratio:20%-25%).22 well large-scale fracturing treatments have been completed with the average amount of proppant of about 75 m3 per well,average oil production per well 22 t/d after fracturing form 0.8 t/d before the treatment and showed significant production increase.It is proved that the massive fracturing can improve development efficiency of Block F142 providing reference for the development of similar reservoirs.
