摘要： 吐哈盆地不仅油气藏类型丰富,而且油气层电阻率显示特征也纷繁复杂,既有高电阻率水层,也有低电阻率油气层,同时也有正常的高电阻率油气层。其中,低电阻率油气层因其电性特征与水层及其围岩差别甚小,最难识别,往往容易忽视而被漏失掉。通过近几年对台北凹陷西部老井复查解释,不仅发现了一批低电阻率油气层,而且对此类油气层的识别也形成一套较为成熟的技术,系统总结低电阻率油气层的特征、形成机理及其测井评价方法,对今后这种类型油气层的解释、评价具有一定的指导意义。

Abstract: Various types of oil-gas reservoirs occur in Turpan-Hami basin, with complicated features of response display of oil-gas beds. There are high resistivity aqueous stratum, low resistivity oil-gas stratum, and normal high resistivity oil-gas stratum in the same time. As the electric response of low resistivity oil-gas stratum showing a little difference with their surrounding beds and aquifer bed, it is hard to be identified, tending to be overlooked and ignored. In recent years by reinvestigation of old wells situated in west Taibei depression, a number of low resistivity oil-gas beds has not only been discovered, but also the relative matured techniques for such identification established. The paper systematically summarized the peculiar response of low resisitivity oil-gas beds,physical mechanism and well- logging data evaluation method, which have constructive meaning for explanation and evaluation of such type oil-gas beds.

Key words: Turpan basin, Hami basin, Taibei sag, resistivity, oil and gas migration, mechanism, well-logging interpretation
