Research and Application of Potential Tapping and Efficiency Enhancement Technology in Low Permeability Oilfield

With the extension of development time in low-permeability oil fields, the production decline and water content increase in some blocks accelerate, and the conventional water drive adjustment effect gradually deteriorates. The difficulty of tapping potential adjustment increases, and the development efficiency is relatively poor. This article conducts research and application of potential tapping and efficiency enhancing technologies to guide the transition from precision development to precision development in oil fields, comprehensively upgrading development work, exploring technology management models to improve development effectiveness and efficiency under low oil prices, and enhancing block development effectiveness. Through comprehensive governance, the natural decline rate and comprehensive decline rate of Block A have decreased by 2.6 and 3.6 percentage points, respectively. The predicted input-output ratio reaches 1:1.3, and the predicted increase in oil recovery rate is 1.2 percentage points. The governance effect is outstanding. The potential tapping and efficiency enhancing technology proposed in this article is applicable to low permeability oil fields, can improve the development effect of blocks, and can be promoted and applied in similar blocks, which has certain guiding significance for oilfield water drive development.
