摘要
目标储层油气检测一直是勘探的难点之一,目前已成为影响钻探成功率的主要因素之一。常规的油气检测技术由于受地表氧化还原带、地面地质条件等多种因素的影响,油气预测的成功率相对较低;时频电磁法(TFEM)直接研究深层油气目标,激发探测目标本身产生的异常,从而克服了近地表的干扰,提高了油气预测的精度。TFEM勘探在伊犁盆地取得了较好的勘探效果,成功地预测了目标储层的含油气性,并确定了含油气有利区。
Oil and gas detection of deep targets is one of the difficult points for petroleum exploration all the time.It is the major factor limiting drilling success rate.Conventional oil and gas detection methods are limited by the surface oxidation-reduction zones and geology condition,the success rate of hydrocarbon prediction is very low.The time-frequency electromagnetic(TFEM)method directlystudies,induces and detects deep target reservoirs.It can overcome surface interferences and increase the precision of hydrocarbon detection.A TFEM survey was designed and conducted in Yili Basin,China.Based on TFEM data,hydrocarbon potential of targets are assessed and the favorable zones are predicted accordingly.
