    • 摘要: 针对岩心渗吸实验周期长和计量难度大等问题,设计了不同尺寸、不同边界条件的裂缝-基质微流控模型,并通过表面性质修饰对模型润湿性进行调控,开展了油-水、油-润湿改性体系、油-Winsor Ⅲ型表面活性剂体系的一系列渗吸实验并研究其渗吸机制.研究表明,在油-水、油-润湿改性体系渗吸过程中,油相通过海恩斯阶跃采出,毛细管回压是阻碍基质油相排出的主要阻力,界面张力的降低导致海恩斯阶跃减弱,降低了排油速度,提高了油相采出程度;油-水和油-低界面张力的润湿改性体系渗吸是毛管压力主导的逆向渗吸过程,各个边界对渗吸的贡献程度相近,与经典渗吸标度方程拟合较好;油-Winsor Ⅲ型表面活性剂体系渗吸是在超低界面张力条件下由重力主导的顺向渗吸过程,实质上是中相微乳液的形成与再平衡过程,其在微观模型中的渗吸动态与前人渗吸标度方程的修正模型拟合较好.

    • 摘要: 塔里木盆地库车坳陷大北气田具有储集层埋深大、岩性致密、基质孔隙不发育和裂缝发育的特征.实验研究表明,大北气田储集层具有强烈的压力敏感性,并且气层一旦产生压力敏感,会导致裂缝闭合,造成储集层物性的永久性损害,产量急剧下降.通过岩心压力敏感实验,确定了大北气田储集层产生压力敏感的静压力;在求取气藏所受构造应力场的基础上,结合地层实际压力,确定了大北气田不同构造位置气藏产生压力敏感的具体地层压力.在气田开采过程中,应在气藏压力降低到敏感值前及时采取措施,控制压力敏感的发生,以维持产量,提高采收率.

    • 摘要: 为提高塔河油田裂缝性油藏的酸压改造效果,研究了CO2对裂缝性油藏酸岩反应影响的问题.利用自主研制的裂缝性储层酸岩反应仪,基于网状裂缝模型,对考虑CO2影响的不同类型、不同黏度和不同浓度酸液的酸岩反应情况进行了试验评价.试验得出:随着回压增大,酸岩反应产生的CO2转变为超临界态后大量溶于酸液中,酸液流动阻力大幅降低,酸蚀量增大;与胶凝酸及Ⅰ型地面交联酸相比,HCl质量分数为20%的Ⅱ型地面交联酸滤失量小、黏度高,受CO2影响最大,酸岩反应最慢,有利于实现裂缝性储层深穿透酸压的目的.Ⅱ型地面交联酸在YJY井重复酸压中进行了现场试验,与该井应用胶凝酸的首次酸压效果相比,液体效率大幅提高,酸蚀缝缝长大幅增加,压裂后累计产油12×104 t,增油效果显著.研究表明,超临界CO2有助于降低酸液流动阻力,提高酸液深穿透能力,提高塔河油田裂缝性储层酸压改造效果.%To enhance acid fracturing performance in fractured reservoirs in the Tahe Oilfield,research has been conducted to highlight the impact of CO2 on acid rock reactions in such reservoirs.By using independently developed acid rock reaction instruments and a fracture network model,tests were conducted to study the impact of CO2 on acid rock reactions with different acids,viscosity and concentration.Test results showed that flow resistance of acid may decrease sharply as CO2 generated during acid rock reaction become supercritical,then dissolve in acid massively as back pressure increases.Compared with gelled acid and Type I surface cross-linked acid,Type II surface cross-linked acid with concentration of 20% has less filtering loss,higher viscosity and susceptibility to CO2 and lower acid rock reaction speed.This kind of acid may facilitate acid fracturing to achieve deep penatration in fractured reservoirs.A pilot test was conducted for Type II surface cross-linked acid in the acid refracturing of the Well YJY.Compared with the primary acid fracturing with gelling acid,both fluid efficiency and fracture length increased dramatically.With cumulative oil production of 12×104 t after refracturing,productivity enhancement performance has been observed.So research results showed supercritical CO2 could effectively reduce flow resistance of acid,enhance acid penetration and promote the performance of acid-fracturing of fractured reservoirs in the Tahe Oilfield.

    • 摘要: 水力压裂和基质酸化对裂缝性致密砂岩储集层的增产改造都有很大的局限性.酸化压裂应用于该类储集层,增产效果非常显著.针对具体储集层计算了天然裂缝产生剪切滑移的条件,同时模拟了酸液对钙质充填裂缝以及剪切滑移裂缝的作用效果.研究表明,与常规增产作业相比,酸压主要依靠2种作用获得较高的导流能力:天然裂缝在水力作用下发生剪切滑移,裂缝能依靠其表面的凹凸不平形成自支撑;酸液溶蚀裂缝中充填物、伤害物以及部分岩石基质使得残余裂缝未闭合空间增大,从而增加了裂缝的导流能力.在机理研究的基础上给出了工艺实施建议.

    • 摘要: 塔里木盆地某气田下白垩统巴什基奇克组储集层属于典型的低渗裂缝性砂岩储集层,由于经历构造运动期次多、埋藏深度大、夹层发育,储集层裂缝演化发育规律复杂.目前常用的裂缝描述方法(包括医用CT)存在精度低、定量评价效果差等不足.利用ICT层析扫描成像技术(工业CT)对该气田低渗裂缝性砂岩岩心内部裂缝进行了精细扫描成像,在此基础上对裂缝形态特征、产状、充填特征、空间组合和裂缝成因分类进行了系统研究.研究结果指出,研究区裂缝以高角度构造缝为主,可划分为张性缝、剪切缝和多期混合缝,裂缝形态有直线型、折线型、复杂网状、穗状和帚状等类型,首次发现裂缝发育复杂的“多层充填结构”,ICT扫描裂缝孔隙度主要为0.01%~0.04%.

    • 摘要: For fractured reservoirs ,water shutoff and profile control measures often failed and are inef-fective due to serious leakage of plugging agent in formation .To address this problem ,two groups of par-tially hydrolyzed polyacrylamide (HPAM )are reacted with two crosslinking agents to generate a high-strength polymer plugging agent .Through analysis ,an optimum formula of ingredients is defined as fol-lows :5 000 7 000 mg/L HPAM + 125 mg/L organic chrome crosslinking agent + 80 mg/L phenol+ 120 mg/L urotropine+80 mg/L intensifier .Influences of temperature ,pH value and salinity on the profile con-trol system were studied ,and the gelling performance of double-group secondary crosslinking system was compared with two crosslinking agents separately .The single-barreled and double-barreled parallel cores were used in plugging test to simulate the profile control ,the results show that plugging rate is over 99%and break-through pressure gradient higher than 36 M Pa/m for single-barreled cores .For the double-bar-reled parallel cores ,the plugging rate of high permeability core is over 98% ,and that of low permeability core is less than 15% .It is concluded that double-group secondary crosslinking system can prevent plug-ging agent from leaking in the fractures ,and greatly reduce possibility of plugging the passageway of oil and gas when it penetrates into the micro-fractures .This system is prospective for profile control in frac-tured reservoirs .%针对裂缝性油藏调剖堵水措施成功率低、效果差,堵剂在注入过程中漏失严重等问题,研制了一种利用部分水解聚丙烯酰胺(H PA M )的2个不同基团分别和2种交联剂反应形成高强度的聚合物调剖体系。经过组分用量分析,确定适用配方为:5000~7000 mg/L HPAM+125 mg/L有机铬交联剂+80 mg/L苯酚+120 mg/L乌洛托品+80 mg/L增强剂,考察了温度、pH值、矿化度对该调剖体系性能的影响,对比了双基团二次交联调剖体系与2种交联剂单独使用时调剖体系的成胶性能。采用单管和双管并联岩心封堵试验模拟调剖体系的调剖过程,试验结果表明,调剖体系对单管岩心的封堵率高于99%,突破压力大于36 M Pa/m ;对双管并联岩心中高渗岩心的封堵率在98%以上,对低渗岩心的封堵率低于15%。研究表明,双基团二次交联调剖体系可以降低在裂缝中的漏失,减轻进入微裂缝对油流通道造成的堵塞,在裂缝性油藏调剖堵水中具有良好的应用前景。

    • 摘要: 通过岩心力学实验及区块地应力建模,并采用理论分析、数值模拟和实例分析等方法,研究超深裂缝型储集层压裂过程天然裂缝剪切破裂机理证明,当天然裂缝中孔隙压力达到其开启临界值时,天然裂缝发生剪切破坏,而弱面胶结且倾角接近60°的天然裂缝更容易发生剪切破坏;压裂施工压力与天然裂缝中孔隙压力呈线性增加关系,超深储集层压裂中的天然裂缝难以实现全部开启:目前工况条件下压裂裂缝沿着天然裂缝发育段开启,压裂难以实现岩石本体的破裂,而且部分处于有利方位的天然裂缝不能开启.通过优化排量、加砂量等压裂参数和泵注程序,可提高裂缝型储集层的压裂改造体积,现场应用取得较好效果.

    • 摘要: 在储层裂缝发育的油气井修井作业中,为了阻止工作液进入裂缝,避免裂缝被堵塞,实现储层保护,基于修井作业中裂缝性储层损害机理研究成果和利用特种材料在裂缝端部形成暂堵的思路,研制出了一种新型裂缝暂堵剂.该暂堵剂在室内性能测试中能够对缝宽为1~2 mm的人造裂缝形成暂堵,暂堵材料在裂缝端部形成堆积而很少进入裂缝内部,容易解堵.大庆油田5口气井现场应用结果表明,该暂堵剂能够承受30 MPa的正压差和140°C的地层温度,暂堵形成后能够大幅度减少工作液进入储层,不仅实现了对储层的保护,还能够依靠负压顺利解堵,作业后气井产能基本保持了作业前的水平.这说明在修井作业中采用暂堵技术保护裂缝性储层是可行的.%In order to protect fractured reservoirs during workover,a new temporary fracture plugging agent was developed on the basis of research on damage mechanism of fractured reservoirs and the concept of temporary plugging at tips of fractures with special materials. This agent could keep the operating fluid from flowing into the fractures and decrease the flowing resistance of oil and gas. In laboratory test, it formed temporary plugging for 1-2 mm artificial fractures, which could be removed easily since the plugging materials just accumulated at the tips of fractures and rarely entered into the fractures. The field application in Daqing Oilfield indicated that this agent could work under a positive differential pressure up to 30 MPa and a formation temperature up to 140°C. The temporary plugging cut off the operating fluid invading the reservoir,so that damage was avoided,and the plugging could be easily removed by negative pressure. After workover, the production rate of the gas wells recovered by nearly 100%. This suggested the feasibility to adopt temporary fracture plugging in workover to protect the fractured reservoir. Nevertheless, further study should be made on such technology, to prevent the production decline of gas well after the workover operation.
