摘要
固井环空窜流是所有油气井固井过程中都要面临的一个潜在固井技术难题,也是相当一段时间来国内外固井界面临的一个最为棘手的技术难题。固井后发生窜流将损坏储层,影响产能,对油气田开发后续作业造成不利影响,严重时将导致油气井报废,浪费资源。
     本文论述了环空窜流的成因及其类型,从理论上阐述了气窜过程。论述了窜流潜能因子、静胶凝强度、潜气窜系数(GFR)、气窜因子(FGFP)、气体运移指数、胶凝失水系数(GELFL)、水泥性能系数的防窜评价体系,介绍了胶乳水泥浆、纤维水泥浆等一系列防窜水泥浆体系。本文通过试验研究优选封堵液外加,提出了新的封堵液配方:封堵材料+0.2%FS-800S+3%WD-830L+12%PS-1+3%JS-210L+15%JR-800L+0.5%XP-800L+30%砂+5%硅粉。在室内进行封堵液气窜试验研究,分析了封堵液封堵效果及机理,结果表明封堵液能封堵环空微裂缝,为固井防气窜提供了一个新的方法。
     本文针对庆深气田自身特点,优选出适合于庆深气田固井的水泥浆体系:G级水泥+4.0%WD-830L+1.8%PS-1+3.5%JS-210L+0.3%FS-800S+15%JR-800L+0.5%XP-800L+35%砂+5%硅粉+0.5%DZF-1+2%BXP-1。对水泥浆体系防水气窜性能进行室内实验评价,分析了水泥浆体系与气窜的关系、水泥石的显微结构。结果表明该水泥浆体系具有抗高温(180℃)、微膨、增韧、防水气窜等特点,能够有效抑制环空界面间隙的形成,从而更好地解决庆深气井的固井质量问题,为庆深气田固井过程中解决防气窜问题提供了一个新的途径。
All oil well cementing process face the problem cementing central channeling air, and it is a potential technical problem in cementing. Cementing central channeling air is one of the most difficultly technical challenges and it should be a considerable period of time to cementing the sector. Cementing after channeling has a bad effect on reservoir and productive, and sometimes it will lead to serious abandoned oil and gas wells and waste of resource.
     This paper discussed the central channeling air flow and the types of causes from the theory, expounded gas channeling process, discussed channeling potential factor, static gel strength, potential gas channeling coefficient (GFR), gas channeling factor (FGFP), gas migration index, cementitious local coefficient (GELFL), cement coefficient of performance evaluation of the anti-channeling system, introduced latex cement, fiber cement and a series of anti-cement slurry system. A new anti-channeling sealing liquid, blocking material+0.2%FS-800S+3%WD-830L+12%PS-l+3%JS- 210L +15%JR-800L+0.5%XP-800L+30%grit+5% silica power, is used sealing gas channeling, and optimization the sealing liquid formulation institute the effect of sealing liquid for gas channeling plugging. The results showed fluid sealing can seal cementing cracks for anti-gas channeling, so a new approach should be provided to improve the quality of cementing guarantee.
     This article aims to optimize the cement slurry system, G cement + 4.0%WD -830L+1.8%PS-l+3.5%JS-210L+0.3%FS-800S+15%JR-800L+0.5%XP-800L+35%grit +5% silica power+0.5%DZF-1+2%BXP-1, which is fit for the cementation for high temperature and pressure gas well avoiding the tendency towards gas migration. This cement slurry system has many advantages, such as anti-high temperature (180℃), right-angle colloid, against water/gas breakthrough and favorable rheological property. The article also evaluates the performance of cement slurry as a gas block, researches and analyzes the relationship among the microscopic composition of cement stone, the slurry system and the gas migration, and then found the cement slurry with fiber tenacity latexes is more effective, for its strengthening anti-shock ability of amulus interspaces. The performance of cement slurry as a gas block can be improved to a great extent. Thereby, the problems associated with high temperature and pressure cementation can be solved much better. It settles a base for cementing quality and provides a new way to avoid water/gas migration during cementation.
