摘要:
水平井为渤海S油田在高含水期实施挖潜的主力井型，掌握水平井含水规律对油田实施挖潜调整具有重要意义。以渤海S油田水平井实际生产数据为依据，将水平井含水上升类型归纳为凹型、凸型和直线型。系统分析了主导水平井含水上升类型的主要影响因素。研究认为，渤海S油田水平井含水上升模式的主控因素为井区采出程度、油层厚度和周边定向井含水率，并根据三大主控因素绘制了水平井含水上升模式的判别图版，提出了三种含水类型水平井不同含水阶段的相应稳产策略。运用所建立的图版，可以快速判别潜力区域部署的新水平井的含水上升类型，并制定合理的调控策略。矿场实践表明，建立的水平井含水上升模式判别图版简便实用、准确度较高，据此提出的水平井调控策略合理，具有较好的推广价值。
Abstract:
Horizontal wells are the main well type used to tap the potential of Bohai S Oilfield during the high water-cut period. Understanding the law of water-cut in horizontal wells is of great significance to the implementation of potential tapping adjustments in oilfields. Based on the actual production data of horizontal wells in Bohai S Oilfield，the types of water-cut rise in horizontal wells were classified into three types of water-cut rise patterns: concave，convex，and linear. On this basis，the main influencing factors of dominant water-cut rise type in horizontal wells were systematically analyzed. The study results indicate that the main controlling factors for the water-cut rise pattern of horizontal wells in Bohai S Oilfield are the recovery degree of the well area，the thickness of the oil layer，and the water-cut of the surrounding directional wells. Based on the three main controlling factors，a discriminating chart of the water-cut rise pattern of horizontal wells was drawn. It was proposed three water-bearing types of horizontal wells and corresponding stable production strategies at different water-bearing stages. Using the established chart，it is possible to quickly distinguish the type of water-cut rise of the new horizontal well deployed in the potential area and to formulate a reasonable control strategy. The field practice shows that the established horizontal well water-cut rising mode discriminant chart is simple，practical，and highly accurate. Based on this，the proposed horizontal well control strategy is reasonable and has good promotion value.
