摘要： A method of converting a completed well into a dual completed well that includes selectively pumping a water-based fluid into a first production zone of the completed well, wherein the water-based fluid has a pH of greater than about 5; allowing the water-based fluid to form a continuous, non-flowing water-based gel in the first production zone of the completed well, wherein the water-based gel has a pH of greater than about 5; disposing a layer of cement into the completed well above the water- based gel; perforating a second production zone of the completed well in a location above the layer of cement; drilling through the layer of cement; and breaking the water-based gel located in the first production zone of the completed well, wherein the breaking comprises: exposing the water-based gel to a breaker fluid, wherein the breaker fluid has a pH of greater than about 5 is disclosed.

摘要： A method of electrically logging subterranean wells using a conductive double emulsion fluid includes a miscible combination of an oleaginous fluid, an emulsifier capable of forming a microemulsion, an emulsifier capable of forming an invert emulsion, and an electrolytic salt. A microemulsion is the continuous phase of an invert emulsion. The electrolytic salt or brine of the salt is present in a concentration sufficient to permit the electrical logging of the subterranean well. The fluid may additionally contain a polar organic solvent and a carbon dioxide buffer. The polar organic solvent may be an oil soluble glycol or glycol ether such as ethylene glycol, diethylene glycol, propylene glycol, polypropylene glycol, and the like. The electrolytic salt preferably is a quaternary amine salt having the formula: wherein R is an alkyl having 8 to 18 carbon atoms, R′ is 2 to 6 carbon atoms alkyl group, B is hydrogen, oxyalkyl having 1 to 4 carbon atoms or alkyl having 1 to 4 carbon atoms, A is hydrogen or alkyl with 1 to 4 carbon atoms, x+y=1 to 15, z is 0 to 3, and M− is a counter anion; or combinations thereof. In such instances the quaternary amine salt serves both as the electrolyte and the microemulsifer. The carbon dioxide buffer is preferably a trialkylanol amine.
摘要翻译：使用导电双乳液流体对地下井进行电测井的方法包括油性流体，能够形成微乳液的乳化剂，能够形成反相乳液的乳化剂和电解质盐的可混溶组合。微乳液是反相乳液的连续相。盐的电解盐或盐水的存在浓度足以允许对地下井进行电测井。流体可另外含有极性有机溶剂和二氧化碳缓冲液。极性有机溶剂可以是油溶性二醇或二醇醚，例如乙二醇，二甘醇，丙二醇，聚丙二醇等。电解盐优选是具有下式的季胺盐：其中R是具有8至18个碳原子的烷基，R'是2至6个碳原子的烷基，B是氢，具有1至4个碳原子的烷氧基或具有 1至4个碳原子，A为氢或具有1至4个碳原子的烷基，x + y = 1至15，z为0至3，M 1为抗衡阴离子; 或其组合。在这种情况下，季胺盐既用作电解质又用作微乳剂。二氧化碳缓冲液优选为三烷基醇胺。
