唐山地震前后渤海湾地区油井动态的异常变化

ANOMALOUS VARIATIONS IN OIL WELLS DISTRIBUTED IN THE BOHAI BAY OIL FIELD BEFORE AND AFTER THE TANGSHAN EARTHQUAKE OF 1976

  • 摘要: 本文汇集和分析了唐山地震前后(1970——1980年),渤海湾地区各油田的油井动态资料,结果表明:一、大地震的孕育和发生对油井动态有所影响.二、唐山地震前的油井动态异常主要表现为油产量和井压的大幅度升降.三、唐山地震前后井口压力实测曲线形态与水压致裂法测量地应力时,岩石破裂前后的曲线很相似.四、天然地层压力驱动的油井显示了清楚的震前变化,但这类井在油田只占极少数,而且迟早会转化为人工驱动型井,使问题复杂化.
    Abstract: In this paper, the authors collect and analyse all available data from oil wells in the Bohai Bay Oil Fields before and after the Tangshan Earthquake from 1970 to 1980. They show certain anomalous phenomena as follows:(1) The data reveal that the oil production in wells is apparently influenced by the development and occurrence of earthquakes.(2) The anomalous variations consist mainly in the quantity of oil production and pressure in wells before the Tangshan Earthquake.(3) The curve of pressure variation measured at the casing head is similar to that by the method of hydraulic fracturing before and after fracturing of rocks.(4) The anomalous variations before the Tangshan Earthquake in natural oil producing wells, not yet influenced by man-made effects, show rather clearly. But such wells are very few in number and sooner or later will be turned to artificially driven ones, and become complicated.
