    Abstract
  • The Longmaxi formation in the Changning block (Sichuan Oilfield) is drilled with oil-based drilling fluids. This formation is developed with microfractures and hence mud losses have frequently happened in the past. Mud losses have been controlled with bridging particles formulated in oil-based slurries, which has been proved unsuccessful and time consuming. To deal with this problem, a compound oil-based gel has been developed with animal fats, vegetable oils and epoxy resin. This oil-based gel can invade into the fractures in the formation rocks to seal them off, thereby increasing the success rate of mud loss control. Considering the practicability of field application, the compressive strength, thickening time and performance against contamination from oil-based muds of this gel were evaluated in laboratory test, and its ability to combat mud losses was also evaluated. The laboratory test results have shown that the gel has compressive strength of 5.1 MPa, and the gelling time can be controlled at more than 3 hours, which is enough to perform field operation safely. Oil-based drilling fluids have only a very slight effect on the gel strength of the gel and do not cause the thickening time of the gel to shorten. All properties of the oil-based gel indicate that it is suitable for use in controlling mud losses through microfractures in hole sections drilled with oil-based drilling fluids.
