Purpose and description of task (project)
Conducting fundamental scientific research based on a systematic approach, using the electrical basis of the morphology of rock cracks and the physico-chemical basis of high-strength sealing technology based on the prediction of crack morphology.
Forecast method + clogging technology + formulation of the material
The development of cracks in the weathered reservoirs of heavy oil on the ancient buried hills of the field led to serious leaks during drilling of 80% of wells, and the circulating drilling fluid could not exit the borehole. The current uncertainty in predicting the morphology of the crack leakage channel and the mechanism of bridge leakage in collectors leads to a long leakage operating time (more than 48 hours), a low leakage success rate (less than 15%) and a low crack leakage pressure (less than 1.0 MPa). This poses a risk to the safety of well monitoring and the quality of reservoir cementing, as well as leading to an increase in drilling costs.
-A method for predicting logging of parameters of the leak channel of destroyed wells based on experiments on the electricity of rock fractures (patent); -High-strength fast-consolidating plugging agent (recipe), suitable for leaks in fractured reservoirs; -Leak plugging technology (technical report, on-site process design and technological regulations), based on rapid filtration and consolidation of fractured reservoirs.
