胡154区块富县组油藏高效开发技术政策研究

Technology Policy Research of High-efficient Reservoir Development in Fuxian Formation of Block Hu 154

胡154区块富县组油藏位于胡尖山油田中西部，目前1口井试注，需要进行高效开采技术政策研究。应用油藏工程理论分析、矿场数理学统计和数值模拟方法，系统对油藏进行评价和分析，论证油藏注水开发合理技术政策，建议采用菱形反九点井网十边部不规则井网部署井网、200～300m井距、单井产能1．49-2t／d、合理生产压力5～7MPa、单井日配注量18m^3、合理注采比0．9～1．0等技术政策界限进行开发。设计注水开发方案3套，推荐按合理技术政策指导注水方案进行开发，根据实际油水运动调整单井配注。

The reservoir of Fuxian Formation in Block Hu154 was located in the midwest of Hujianshan Oilfield,currently only one well was used for water injection,it was needed for research of technology policy for high efficient development.By using reservoir engineering theory analysis,field mathematical statistical and numerical simulation methods,the reservoir was systematically evaluated and analyzed to demonstrate the technology policy of reasonable reservoir waterflooding development.It was suggested that an inverted nine-spot rhombus well pattern+edge irregular well pattern was used,the technical policy included that the well spacing was 200~350m,single well productivity was 2~3t/d,reasonable production pressure draw-down was 6~8MPa,oil production rate was 1.0%~1.2%,daily single well water allocation was 18m3/d and reasonable injection-production ratio was 0.9~1.0.Three sets of waterflooding development programs are designed,and it is recommended that rational technical policy should be used to guide the water injection scheme,adjust single well injection according to actual oil and water movement.
