Analysis of Favorable Injection-production Area Near the Fault Where the Directional Wells Were Deployed

Through the large-scale application of directional well technology, X development zone has achieved good potential tapping effect near fault. However, with increase production batches wells, proportion high-yield wells decreases, and difficulty location optimization increases gradually. In order to further improve recovery fault, under condition sand body in study area, this paper focuses on analysis deployment area conducive high yield from perspective injection-production relationship. Combined practice 48 that have been deployed results, distribution is evaluated three aspects pattern, spacing location, principle are determined. The favorable for fault summarized, which indicates direction improving oil old oilfield.
