胡尖山油田安201区块长61油藏属于典型的裂缝性油藏,自2009年投入开发以来,暴露出部分区域高水饱、主向井裂缝性见水、侧向油井见效缓慢,低产井比例高、合理生产压差不确定、水驱动用程度低、产量递减较大等问题,制约了油田高效开发。论文针对安201区块开发中暴露出的主要矛盾,通过对开发方式、井网系统、注采压力系统、注水参数等综合分析研究,提出适合该类裂缝性油藏合理的开发技术,为同类油藏后期的开发具有指导意义。
Block 61 of Hujianshan Oilfield, Block 61, belongs to a typical fractured reservoir. Since it was put into operation in 2009, some reservoirs have been exposed to high water saturations. Fractures of the main wells have seen water. Lateral wells have shown slow-response and low-yield wells High, reasonable production pressure is uncertain, low level of water-driven use, large decline in production and other issues, restricted the efficient development of the oil field. In view of the main contradictions exposed in the development of Block An 201, this paper presents a reasonable development technique suitable for such fractured reservoirs through comprehensive analysis and research on development methods, well pattern, injection and discharge pressure system and water injection parameters, The late development of the reservoir has guiding significance.
