摘要： A lightweight cross-linked gelled settable cement fluid system derived by pre-hydrating a water gelling agent, and then using that to mix with a cement blend which results in a very stable cement blend, which will matriculate through any fluid and not disperse, and form a cohesive plug wherever it comes to rest; wherein the fluid is injected at the bottom of the 10 pound/gal brine, and the fluid rises to the top of the brine where it reforms into a cohesive plug and hardens; and wherein the fluid can be applied to any density solution, and provide stability and cohesiveness to any settable plug; and wherein the cement/gelled water mixture is then cross-linked using standard hydraulic fracturing cross-linkers to provide a stable structure and ability to matriculate through another fluid and not disperse into that fluid. In a second embodiment the lightweight cross-linked gelled settable cement fluid which is cohesive and stable to be used as a balanced plug during cementing procedures to avoid the plug from becoming dilute in order to develop compressive strength, prevent fluid interchange from occurring and ensuring that all the cement placed would set in place.
