摘要： A method of controlling and delaying the inversion of a drilling fluid and the wettability s of a filtercake by using a delayed phase changing agent. The filtercake is preferably formed while drilling a subterranean formation using a drilling fluid includes: an oleaginous fluid; a nono-leaginous fluid; an amine surfactant having the structure: wherein R is a C 12 -C 22 aliphatic hydrocarbon; R' is an independently selectable from hydrogen or C 1 to C 3 alkyl; A is NH or O, and 1 ≤ x+y ≤ 3. In the method, the filter cake is exposed to a delayed phase changing agent selected from the group consisting of aliphatic amine acids, salts of aliphatic amine acids and combinations thereof. In one preferred illustrative embodiment, the delayed phase changing agent is delivered in the form of a pill, the pill including a carrier fluid, a viscosifier and the delayed phase changing agent. The delayed phase changing agent may be selected from ethylene diamine tetraacetic acid, alkali metal salts of ethylene diamine tetraacetic acid and combinations of these and similar compounds.
摘要翻译：通过使用延迟相变剂控制和延迟钻井液的倒置和滤饼的润湿性的方法。滤饼优选地在使用钻井液钻地层时形成，包括：含油液体; 非致命的流体; 具有以下结构的胺表面活性剂：其中R是C 12 -C 22脂族烃; R'可独立地选自氢或C 1至C 3烷基; A是NH或O，1 <= x + y <= 3.在该方法中，滤饼暴露于选自脂族胺酸，脂族胺酸盐和其组合的延迟相变剂。在一个优选的说明性实施方案中，延迟相变剂以丸剂的形式递送，丸剂包括载体流体，增粘剂和延迟相变剂。延迟相变剂可以选自乙二胺四乙酸，乙二胺四乙酸的碱金属盐，以及这些和类似化合物的组合。
