• Metal-crosslinked polymer gels and breakage thereof

  公开号：EP0505169A1

  公开（公告）日：1992-09-23

  Metal-crosslinked polymer gels, useful in oil and gas well treating operations, contain an esterified chelating agent for the metal ion, which hydrolyses over a period of time, eg. at elevated downhole temperatures, to form the chelating agent which then removes the metal ion from the polymer and breaks the gel. Thus, the cross-linked viscous gel is used as such downhole and thereafter broken for removal.

  在油气井处理作业中使用的金属交联聚合物凝胶含有一种酯化的金属离子螯合剂，这种螯合剂会在一段时间内（例如在井下温度升高的情况下）水解，形成螯合剂，然后将金属离子从聚合物中去除，并使凝胶断裂。这样，交联的粘性凝胶就可以在井下使用，然后再破碎清除。

  The flow of a stimulation fluid may be diverted from a high permeability zone to a low permeability portion of a subterranean formation by use of an acid soluble or acid degradable solid particulate and a composite of an acid or an acid generating compound adsorbed onto a water-insoluble adsorbent. Conductive flow of hydrocarbons from an occluded fracture may be resumed by release of the acid from the adsorbent or the acid generating compound.

  使用酸溶性或酸可降解固体颗粒以及吸附在不溶于水的吸附剂上的酸或酸生成化合物的复合材料，可将激发流体的流向从高渗透区转移到地下地层的低渗透区。从吸附剂或酸生成化合物中释放出的酸可恢复碳氢化合物从闭塞裂缝中的导流。
