    • 摘要: 深水钻完井工程成本高、作业条件苛刻、安全风险大,一旦发生严重的储层损害就有可能导致油气产能大幅度降低,造成巨大的经济损失.为了给深水油气钻探开发中制定和实施储层保护技术措施提供支撑,借助X射线衍射、压汞、扫描电镜、水化膨胀分散实验以及储层敏感性流动实验等手段,分析了中国南海某深水气田储层损害的机理,提出了储层保护技术对策,构建了适合该深水气田储层保护的钻井完井液.研究结果表明:①该深水气田储层为高孔高渗砂岩储层,黏土含量平均为12.38%,存在着强速敏性和中等程度的水敏性;②储层损害的主要原因是钻完井工作液中的固相侵入以及工作储层岩石不配伍;③通过理想充填暂堵方法对宽尺寸孔喉有效暂堵是保护储层的关键技术措施;④所构建的水基钻井完井液在2~75°C深水井筒温度下具有稳定的流变性,直接返排解堵岩心渗透率恢复值介于74.5%~92.24%,与隐形酸完井液顺序污染岩心后渗透率恢复值大于86%.现场应用于4 口深水井的效果表明,4 口井均未发生井下复杂情况,作业结束后直接返排解堵,节约了完井作业时间.结论认为,该钻井完井液可以满足深水高孔高渗储层钻井技术的要求,实现了免破胶作业,储层保护效果优良.

    • 摘要: 通常在勘探开发油气过程中会发生不同程度的油气层损害,导致产量下降、甚至"枪毙"油气层等,钻井液是第一个与油气层相接触的外来流体,引起的油气层损害程度往往较大.为减轻或避免钻井液导致的油气层损害、提高单井产量,国内外学者们进行了长达半个世纪以上的研究工作,先后建立了"屏蔽暂堵、精细暂堵、物理化学膜暂堵"三代暂堵型保护油气层钻井液技术,使保护油气层效果逐步提高,经济效益明显.但是,与石油工程师们追求的"超低"损害目标仍存在一定差距,特别是随着非常规、复杂、超深层、超深水等类型油气层勘探开发力度的加大,以前的保护技术难以满足要求.为此,将仿生学引入保护油气层钻井液理论中,发展了适合不同油气层渗透率大小的"超双疏、生物膜、协同增效"仿生技术,并在各大油田得到推广应用,达到了"超低"损害目标,标志着第四代暂堵型保护油气层钻井液技术的建立.对上述4代暂堵型保护油气层技术的理论基础、实施方案、室内评价、现场应用效果与优缺点等进行了论述,并通过梳理阐明了将来的研究方向与发展趋势,对现场技术人员和科技工作者具有较大指导意义.%Formation damage of varying degree during oil and gas exploration and development generally results in reduced production rate or even kill a reservoir. Drilling fluid, as the first foreign fluid comes into contact with reservoir always causes greater formation damage. To mitigate or avoid formation damage caused by drilling fluid and enhance production rate of a single well, plenty of studies have been conducted by scholars at home and abroad for almost half a century. Three generations of drilling fluid technologies capable of protecting reservoir from being damaged have been established, they are "shielding and temporary plugging", "fine temporary plugging" and "temporary plugging with physio-chemical film". These technologies have greatly economically improved the protection done to reservoirs. The progresses made in reservoir protection, although great, still do not satisfy the pursuit of petroleum engineers of"ultra-low" formation damage, especially with great efforts made in developing nonconventional complex, ultra-deep and ultra-deep water reservoirs, the reservoir protection technologies previously prevailing are becoming unsatisfactory. To better protect reservoirs from being damaged, bionics has been introduced in the reservoir protection drilling fluid theory. The wide application of this new theory in large oilfields helps reach the goal of "ultra-low" formation damage, symbolizing the establishment of the fourthgeneration of reservoir protection drilling fluid technology. Theoretical basis, implementation program, laboratory evaluation and field application and advantages and disadvantages of the four generations of reservoir protection technologies are detailed in this paper, and the trend of development of reservoir protection drilling fluid technology is expounded in an effort to be of guiding significance to field technologists and scientific researchers in their work.

    • 摘要: Horizontal well open hole completion is a way of well completion to maximize well production rate.In offshore drilling,well completion is generally done with solids-free drill-in fluid,supplemented with gel-breaking well completion.Direct flowback of drill-in fluid is a technology developed on the basis of this way of well completion.In this paper,parameter design,additive selection and well completion technique were systematically analyzed and evaluated,and the mechanism of reservoir protection of this technology was also analyzed.The composition of the drill-in fluid is as follows:seawater + soda ash/caustic soda + rheology modifier VIS + starch filter loss reducer STARFLO + soluble salt (shale inhibition and mud weight) + high purity sized calcium carbonate MBA.The three functional additives of the formulation can all be liquefied by 0.3% HTA (a chelating agent) solution.The liquefaction of the additives left no residue and the mud cakes in the wellbore and near the borehole wall were all converted to clear saltwater.MBA is a mixture of calcium carbonate powders with five particle sizes.The particles of MBA can be "inter-inserted" with starch to form a mud cake that is much denser.Laboratory experiment has shown that the drill-in fluid had low-shear-rate viscosity of around 30,000 mPa · s,optimum contamination-resistance and flowback ability,and the highest permeability return.After contaminated with 15% drill cuttings,the drill-in fluid still had permeability return of more than 80%.This drill-in fluid was used in twelve wells in three oil fields and one gas field in the east of South China Sea.The maximum temperature at the hole bottom was 60-130 °C,and the highest mud density was 1.20 g/cm3.Three of the twelve wells penetrated low porosity low permeability reservoirs and the rest nine wells penetrated reservoirs with medium to high porosity and permeability.The drilling operation was successful.The use of this technology simplified the process of well completion,saved operational time and cost,and protected the reservoirs from being damaged.%水平井裸眼完井是一种最大限度提高储层开采能力的方式,海上油田常采用无固相钻井完井液并辅以破胶完井的方式来完成钻完井作业.直接返排钻井完井液是在此基础上开发的,对其在参数设计、材料选择、完井工艺等方面进行了分析与评价,并分析了其储层保护机理.该体系基本组成为海水+纯碱/烧碱+流型调节剂VIS+淀粉降滤失剂STARFLO+可溶盐+高纯粒径匹配碳酸钙MBA,3种功能材料均能够被0.3%HTA隐形酸螯合剂溶液液化,液化后无任何残留,使井筒内及近井地带的泥饼全部转化为清洁盐水,MBA由5种不同粒径的碳酸钙复配而成,且和淀粉可以达到互相“镶嵌”的作用,使泥饼更加致密.通过实验评价,该钻井完井液的低剪切速率黏度控制在30 000 mPa·s左右,具有最佳防止污染和返排的能力,且渗透率恢复值最高,可抗15%左右钻屑污染,渗透率恢复值大于80%.该体系在南海东部3个油田、1个气田已应用12口井,井底最高温度为60~130°C,密度最高为1.20 g/cm3,3口井属于低孔渗油藏,9口井属于中、高孔渗油藏,钻井过程顺利.该技术简化了完井方式,节省了作业时间与费用,并具有较好的储层保护效果.

    • 摘要: Nanomaterials have been more and more used in drilling fluids, gaining good results in drilling operation. It has been found in the field application that the nanomaterials always become aggregated as the concentrations increase, making it difficult for the nanomaterials to take effect. Based on the study of the mechanisms of nanomaterial aggregation, a nanomaterial was grafted to render it good dispersity in drilling fluid. The molecules of the nanomaterial have good flexibility and deformability. The molecules of the nanomaterial can be adsorbed on the surface of rocks, thereby enhancing the ability of the nanomaterial to plug micro fractures and fissures. A nanomaterial filter loss reducer has been synthesized to formulate a drilling fluid with other nanomaterial additives, such as lubricant and shale inhibitor. The nanomaterial drilling fluid functions properly at 150 °C, and has properties as follows: API filter loss ≤2.4 mL, HTHP filter loss≤9.8 mL, coefficient of friction≤0.04, percent recovery of permeability of cores ≥ 91%, and percent recovery of drilled cuttings in hot rolling test≥90.5%. Field application has shown that the nanomaterial drilling fluid had good lubricity and reservoirs drilled were effectively protected from being damaged.%针对纳米材料在钻井液中团聚的问题,通过分子设计,改进纳米材料的表面性能,以改性纳米二氧化硅为核,通过接枝柔性聚合物,合成了一种纳米封堵降滤失剂.通过引入强的吸附基团和疏水基团,聚合物分子的亲疏水、氢键等协同作用形成空间的网架结构,使合成的纳米封堵降滤失剂能够以纳米级尺度分散在钻井液中,其在钻井液中纳米级粒度的含量高达59.3%,其不仅具有优异的降滤失性能,同时具有柔性可变形性,还能够吸附在岩石表面,提高纳米材料对微裂缝和小孔隙的封堵能力.以合成的纳米降滤失剂为核心处理剂,并优选出配套的纳米润滑剂、纳米抑制剂,形成纳米钻井液体系.该体系的抗温达150°C,API滤失量在2.4 mL以下、高温高压滤失量在9.8 mL以下、润滑系数不大于0.04,渗透率恢复值不小于91%、目的层井段岩屑回收率≥90.5%.该体系在大港油田枣1510井的应用中表现出良好的润滑性和保护油气层效果.

    • 摘要: Bohai oilfield has long been developed with water injection. Some water injectors are directly put into injection without flowback because of special environmental requirements and time limit, resulting in high injection pressure and deficiency in injection rate. A study has been conducted to resolve this problem, focusing on whether a well was flowed back or not in the early stage. Differences between formation damage caused by the two operations (flow back or not flow back) were extensively analyzed from the types of formation damage and formation damage mechanisms. Extent of formation damage and effects of formation damage by drilling fluid on water injection in late stage were studied. The study showed that drilling and completion fluids caused formation damage in two ways, retention and adsorption of chemicals. Formation damage caused by retention is a reversible process and can to some extent be relieved, formation damage caused by adsorption, on the other hand, is an irreversible process. Laboratory experiments showed that well flowback greatly reduces permeability impairment by drilling and completion fluids. Formation damage caused by drilling and completion fluids is not just a decrease in permeability by retention and adsorption; it also is concerned with the alteration of the properties of rock surfaces which in turn affects water injection in late stage.%渤海油田主要采用注水开发模式,由于受特殊环境及紧迫时效的要求,部分注水井钻完井作业后不返排直接注水,往往造成注入压力高、严重欠注等问题.针对此问题,研究过程中立足于前期是否返排情况,从钻完井液的伤害类型及机理入手,深入剖析2种条件下产生伤害的差异性,开展钻完井液伤害实验对比,分析不同情况形成的伤害程度,同时进一步探求钻完井液伤害对后期注水产生的影响.研究结果表明,钻完井液伤害可分为滞留、吸附2种,滞留伤害可通过返排得到一定程度解除属于可逆过程,而吸附伤害为不可逆过程;对比实验表明,返排过程有利于大幅度降低钻完井液对储层渗透率的伤害;钻完井液形成的伤害并不是简单吸附滞留造成的储层渗透率降低,还与岩石表面性质发生改变有关,从而影响后期注水作业.
