摘要： Methods and compositions for sealing subterranean zones having temperatures in the range of from about 80° F. to about 300° F. are provided. A method of the invention is basically comprised of the steps of providing a subterranean zone sealing composition that becomes substantially rigid when exposed to subterranean zone temperatures above about 80° F. and has a pH above about 8.5 comprised of water, a substantially fully hydrated depolymerized polymer and a cross-linking agent. The sealing composition is introduced into the subterranean zone whereby it becomes rigid and seals the zone. The sealing composition can subsequently be removed by contact with a fluid having a pH below about 8 when a boron compound is utilized as the cross-linking agent.

摘要： Methods and compositions for sealing subterranean zones having temperatures in the range of about 80° F. to about 300° F. are provided. In a method of the invention, a sealing composition of the invention of water, a substantially fully hydrated depolymerized polymer and poly lactic acid, with a pH above about 8.5, is introduced into the subterranean zone wherein it becomes substantially rigid and seals the zone when exposed to subterranean zone temperatures above about 80° F. The methods and compositions are particularly advantageous for use in producing zones because the rigid sealing composition self dissolves over time, freeing the seal and the zone for production of fluids. Moreover, the composition is environmentally compatible.
