Abstract

Abstract: The evaluation of conformance flow water control technology in newly commissioned horizontal wells is usually verified by a single comparison with the offsets, but the comparison results could be greatly unreliable. Water control effect evaluation methods based on the principles of such technology can complement the existing evaluation methods. Conformance flow technology equalizes the output flow profile in each production section of horizontal well, making the axial pressure profile along the wellbore unbalanced. A short shut-in results in the redistribution of axial pressure in the wellbore, and in the process of pressure balance, the fluid in the production section with high water saturation flows out and backflows into the production section with low water saturation. Therefore, there is a correlation between the effectiveness of such techniques and the occurrence of backflow. For example, in Well LFY13-2-A7, where the conformance flow technology water control technology was applied, the water cut was stable at 85% before the well was shut in, and after the well was opened again, the water cut gradually decreased from 90.81% to 85.69% and then remained stable and slightly decreased. This phenomenon, together with referring to the data of the existing adjacent well comparison method, is fully consistent with the mechanism of the conformance flow water control technology, so it proves that this technology has played a role in water control in Well LFY13-2-A7.

Key words: conformance flow water control completion, adjacent well comparison method, water control in horizontal well, evaluation of water control effect
