针对兴古7-H303井投产以来的生产情况,对其进行多方位综合分析,综合采用水力喷射分段加砂压裂技术改造低层,提高渗流能力,实现一趟管柱内完成分层、多段射孔和压裂,其施工周期短,有利于降低储层伤害;不需要机械封隔,能够自动封隔,使潜山压裂有了新突破。同时采用超深水平井潜油电泵方式进行人工举升生产,针对结蜡、结垢严重及油气比高的问题配套采用了相应设备。完善井下气液分离设备,进行防垢试验,实现了该井的高效生产。
Aiming at the production situation of Xingu 7-H303 well since its commencement of operation, a multi-directional comprehensive analysis was carried out. The hydraulic injection fracturing and sand fracturing technology was used to transform the lower reservoir to improve the seepage capacity and to achieve the layered and multi- Perforation and fracturing, the construction period is short, is conducive to reducing reservoir damage; does not require mechanical seal, can automatically pack, buried hill fracturing has made a new breakthrough. At the same time using ultra-deep horizontal well submersible pump for artificial lift production, for waxing, scaling serious and oil-gas ratio supporting the use of appropriate equipment. Improve underground gas-liquid separation equipment, anti-scaling test, to achieve the well of efficient production.
