Fluid loss control method |
摘要 |
A method of temporarily reducing fluid loss into a subterranean formation from a well bore penetrating the formation by way of at least one perforation is provided. A first soluble particulate solid material is introduced into the formation by way of the perforation having a particle size whereby it bridges on the face of the formation and fills the perforation but allows fluid flow therethrough. A second soluble particulate solid material is introduced into the well bore having a particle size such that it bridges on the first particulate solid material and forms a seal over the perforation within the well bore.
