Description

通过控制吸水以促进页岩气生产的微乳液
技术领域
本发明总体上涉及处理穿入地层的钻井的方法。更具体地，本发明涉及一种通过控制吸水以促进页岩气生产的微乳液。
背景技术
某些资料也许仅仅提供了与本发明相关的背景资料，但这些资料可能不会构成现有技术。
水力压裂通常用来开发页岩气储层。九十年代中期，大多数页岩储层是利用交联聚合物液体进行压裂的。为了降低成本，减阻水压裂(slickwater fracturing)作为可选择的方法脱颖而出。减阻水压裂的成功归因于其能够在裂缝面和支撑剂填充层内以最小的压裂液损害接触较大的储层界面。在一个典型的处理方法中，数百万加仑的水以65bpm的平均速率与浓度范围在0.25至1.0ppg的支撑剂被泵入。几种化学物质被加入到处理过程中。普通的添加剂包括阻垢剂、减阻剂、杀菌剂、粘土稳定剂、除氧剂、表面活性剂等。
页岩气储层的减阻水压裂法中一直以来的难题之一是液体回收的后处理。已公布的数据显示注入液体的60％至90％停留在储层中。必须假设这些大量的水在裂缝周围的区域和裂缝本身之内的区域受到截留。该截留液对于相对渗透率和有效流通面积具有负面影响，并且毫无疑问削弱了钻井的生产能力。水的截留可以归因于注入的减阻水和储层页岩之间的界面张力，或者归因于断裂的页岩面之上和附近的毛细管终点效应。为了使截留相减至最小，可以将通常可用的表面活性剂加到减阻水中以减少处理液(即减阻水)和气体之间的表面张力，从而回收更多的处理液并恢复气体的相对渗透性。
对于强水润湿的页岩气储层来说，毛细管作用力促进了孔隙空间内注入的保持；该保持反过来又减少了进入裂缝中的气流。Wardlaw和McKeller(1998)发现具有渣油的气体储层比无油储层能更有效地排水。显然，渣油的存在改变了储层岩石的润湿性使其变得较低地被水润湿。同样，如果将表面活性剂或其他表面涂层化学物质注入页岩气储层，通过减小气-水表面张力而降低了毛细管压力，和/或岩石表面润湿性变得较低地被水润湿。Penny等(1983)通过用溶于甲醇中的表面活性剂将岩石表面的润湿性从水润湿变为油润湿，并成功地减小了水锁效应。Li和Firoozabadi(2000)注意到氟化物表面活性剂可以将水润湿的砂岩和白垩岩的表面变为中等润湿或更加气体润湿。
因此需要提供一种微乳液添加剂，其可以高效改变气体页岩储层的润湿性，将水润湿性变得更加气体润湿。

概述
第一方面，本发明公开了一种处理至少部分含有致密含气砂岩(tight gas sand)和页岩岩石的地层(subterranean formation)的方法。所述方法包括：通过混合溶剂、表面活性剂和辅助表面活性剂而形成溶剂-表面活性剂混合物；向溶剂-表面活性剂混合物中加入水，以形成微乳液；其中地层的润湿性从水润湿变为气体润湿，且地层吸入的水量减少。
第二方面，本发明公开了一种处理致密含气砂岩和页岩的地层的方法。所述方法包括：通过混合溶剂、表面活性剂和辅助表面活性剂而形成溶剂-表面活性剂混合物；向溶剂-表面活性剂混合物中加入稀释剂，以形成微乳液；其中地层的润湿性从水润湿变为气体润湿，且地层吸入的水量减少。
详述
本发明涉及一种微乳液基体系，其能够将页岩气储层的润湿性从水润湿变为中等润湿或更加气体润湿。这将导致在压裂处理过程中吸入页岩地层的水量减至最少。所述微乳液体系是通过混合溶剂-表面活性剂混合物与合适的油基或水基携带液而形成的。
所述溶剂-表面活性剂混合物通常包括溶剂和表面活性剂的组合。在一个实施方式中，所述溶剂选自偶极非质子溶剂，其包括N-甲基-2-吡咯烷酮、二甲基甲酰胺、二甲基乙酰胺和二甲基亚砜。一种特别有用的溶剂为N-甲基-2-吡咯烷酮。所述N-甲基-2-吡咯烷酮因其溶解能力、低毒性和生物降解性而有效。在另一个实施方式中，所述偶极非质子溶剂可以被精制植物油(例如芥花籽油(canola oil))所替代。还可以认为油和不同溶剂的混合(例如芥花籽油和N-甲基-2-吡咯烷酮)也涵盖于某些实施范围内。
所述溶剂-表面活性剂混合物中的表面活性剂一经混合适量水就能够形成水包油微乳液。合适的表面活性剂的某些实例包括以下一种或多种：月桂醇乙氧基化物、直链脂肪醇乙氧基化物(C9-C11)、直链脂肪醇乙氧基化物(C12-C13)、直链脂肪醇乙氧基化物(C12-C15)和聚有机硅氧烷。一种表面活性剂的混合物包括：直链脂肪醇乙氧基化物(C11)、二椰油二甲基四元物(dicocodimethylquaternary)(TomadryN-4)、癸基-二甲基氧化胺和聚有机硅氧烷。
某些示例性的表面活性剂包括但不限于：阳离子、阴离子、两性离子或非离子表面活性剂。在其它实施方式中，所述表面活性剂为粘弹性表面活性剂(VES)流体系统。VES流体系统为用粘弹性表面活性剂和任何其它材料(例如但不限于：盐、辅助表面活性剂、流变增强剂、稳定剂和剪切恢复促进剂，其改善或改良粘弹性表面活性剂的性能)稠化的流体。
有用的VES包括：阳离子、阴离子、非离子、混合、两性离子和两性表面活性剂，特别是甜菜碱两性离子粘弹性表面活性剂流体系统或酰胺基胺氧化物(amidoamine oxide)粘弹性表面活性剂流体系统。合适的VES体系的实例包括那些记载于专利号为5,551,516、5,964,295、5,979,555、5,979,557、6,140,277、6,258,859和6,509,301的美国专利。上述发明中的体系与几类两性离子表面活性剂一起使用时也是有用的。通常，合适的两性离子表面活性剂具有以下通式：
RCONH-(CH2)a(CH2CH2O)m(CH2)b-N+(CH3)2-(CH2)a’(CH2CH2O)m’(CH2)b’COO-
其中R是含有约14至23个碳原子的烷基基团，其可以为支链或直链，并且可以是饱和或不饱和；a、b、a′和b′各自为0至10，以及m和m′各自为0至13；如果m非0则a和b各自为1或2，以及如果m为0则(a+b)为2至约10；当m′非0时a′和b′各自为1或2，以及如果m为0则(a′+b′)为1至约5；(m+m′)为0至约14；且如果CH2CH2O基团或链之一或两者中的O存在，O可以位于朝向或远离季氮的末端。优选的表面活性剂为甜菜碱。
所述表面活性剂组合可以进一步包括辅助表面活性剂，例如二元醇醚。二元醇醚成分可以与溶剂-表面活性剂混合物一起作为溶剂和表面活性剂之间的偶联剂使用，从而稳定微乳液。尽管丙二醇醚为一种有效的辅助表面活性剂，其它合适的二元醇醚还包括但不限于：丙二醇甲醚、丙二醇甲醚醋酸酯、丙二醇正丁醚、乙二醇一丁醚、二乙二醇一丁醚醋酸酯、二乙二醇一丁醚等。
所述溶剂-表面活性剂混合物任选地包括盐。向所述溶剂-表面活性剂混合物中添加盐减少所需作为携带液的水量，还降低钻井处理微乳液的冰点。在为了稳定性和共溶剂替代而加入的盐中，目前优选NaCl、KCl、CaCl2和MgCl。其它合适的盐可以形成自K、Na、Br、Cr、Cs和Bi族。
在本发明的另一个实施方式中，通过有机膨润土(Claytone，organophillic clay)增加了微乳液的粘性。
将溶剂、表面活性剂和二元醇醚混合之后，可以加入稀释剂以形成微乳液。在某些实例中，所述稀释剂为水；但是，也可以使用任何合适的稀释剂。
在一个示例性的实例中，微乳液包含：约15％至20％体积量的表面活性剂混合物(直链脂肪醇乙氧基化物(C-11)、二椰油二甲基四元物和聚有机硅氧烷)、约10％至20％体积量的N-甲基-2-吡咯烷酮、约5％至15％的丙二醇醚，平衡量的水。
所述微乳液可以用于减阻水压裂液。当应用于减阻水时，所述微乳液可以以任何合适的量被加入到携带液中。在某些实例中，约0.2％至2％体积量的微乳液被加入到携带液中。除了其它合适成分之外，减阻水压裂液通常含有水减阻剂、杀菌剂、阻垢剂和粘土稳定剂。
除了减阻水水力压裂液，微乳液还可以用于稠化压裂液、砾石充填、堵水(water conformance control)、酸压裂、注水、钻井液、井眼清理液、防滤失液(fluid loss control fluids)、压井液、隔离液、冲洗液、推进器以及原料(例如水垢、石蜡和沥青的抑制剂)携带物等。使用时，稠化体系可包括聚合物(包括交联聚合物)、粘弹性表面活性剂体系(VES)、纤维稠化体系、纤维-聚合物和纤维-VES混合的体系、减阻水(低粘度)体系等。
除了上述应用之外，所述微乳液还可以用于以下作业：酸化作业、钻井作业和清除硫化氢的应用。并且，应该认识到所述钻井处理微乳液还可以用于其它应用。例如，预期所述钻井处理微乳液还可以用来清洁地面设备和井下设备。
在酸化作业过程中，所述钻井处理微乳液还可以用来传递酸。通常使用的酸液包括氢氯酸、醋酸、甲酸和氢氯酸-氢氟酸。在目前优选的实施方式中，所选的溶剂-表面活性剂混合物(稀释或浓缩)结合酸化携带液以制备适于酸化作业的微乳液。优选地，所述微乳液包括约0.2％-5％体积量的溶剂-表面活性剂混合物和约3％-28％体积量的酸。在一个特别优选的实施方式中，所述微乳液包括约0.2％-5％的溶剂-表面活性剂混合物和约15％体积量的氢氯酸。凝胶化液中钻井处理微乳液的浓度降低了流体与管道接触产生的摩擦，从而便于钻井处理微乳液注入和撤回。
如序列号为12/156,201的美国专利申请记载，使用合适的硫化氢清除剂，微乳液还可以用来清除硫化氢。在这些情况下，该钻井处理微乳液被注入井眼中以便脱去的硫化氢气体通过钻井处理微乳液被“提取”。所述微乳液定期被注入到出现问题的钻井中以减少硫化氢的产生。或者，所述微乳液可以通过毛细管道持续地被注入井下。在另一个实施方式中，所述钻井处理微乳液可以被置于容器中，所述容器被放置于与硫化氢成流体连通。
如序列号为7,392,844的美国专利记载，微乳液可以用来去除管道涂料(pipe dope)和烃类、油基的和合成油基的钻井泥浆以及石蜡和沥青质的分散物。微乳液可以进一步用作排代隔离液体系，或者作为单一隔离液或者作为多重隔离液与第二流体联合，用于在固井之前或引入盐水完井液之前去除油/合成油基的泥饼和烃类。
本发明还包括通常用于这种钻井处理液中的任何添加剂，并且本发明提供的所述添加剂与其它成分是兼容的，并提供了理想的处理结果。所述添加剂可以包括但不限于：分解剂、抗氧化剂、交联剂、阻蚀剂、延时剂、纤维、微粒、支撑剂、砾石、缓冲剂、降滤失剂、pH控制剂、固体酸、固体酸前体等。可以垂直地、倾斜地或水平地处理井眼。
