A plugging mud for eliminating absorption of drilling mud

Journal Article:

Abstract

Developed in the VNIIKRneft' is a plugging mixture (TS) on the basis of urea formaldehyde (carbamide) resin, M-18-62 (SKM), hardened by industrial iron chloride. The studies of the TS showed a reduction in the seizing terms and an increase in the strength of the hardened samples when the hardener content is increased (at a constant temperature) and when the temperature is increased (with a constant hardener content). The density and spreadability of the TS along the AzNII content essentially do not depend on the content of the hardener and are equal to 1.30 gs/cm/sup 3/ and 22-24 cm, respectively. At a temperature above 90/sup 0/C (atmospheric pressure), the hardened samples have a porous structure and a strength of less than 0.4 MPa. With the introduction of sawdust and cord fiber into the TS as a filler, a reduction is observed in the spreadability, strength, seizing terms and the growth in the viscosity with a constant pumpability. With the use of the TS jointly with 1% iron chloride (mineralization in the studies of 300 g/1, included sodium chloride, and chlorides of calcium, sodium and magnesium) established that the additives of mineralized water to 120% per volume increases the seizing times of  More>>

With the use of a clay solution, the seizing terms sharply grow. A complete absence is established of the seizability of the TS with carbonate rocks. Industrial studies, conducted at well 302 of the Besedinsk site of the Orenburg Oblast, confirmed the high effectiveness of the new plugging solution.}
