摘　　要：为提高油气放射性勘查的有效性和更广泛地推广应用,本文仅就勘查过程中的干扰因素,测量结果的推断解释、有利区的评价与准则,以及若干概念等问题进行了讨论。认为,在干旱区的特定季节条件下,只要在野外工作中注意克服干扰因素,即可保证测量结果的质量(重复测量误差一般可保持在10％以下),得到满意的地质效果;指出了在油气放射性勘查结果的推断解释过程中应引起对如下方面的注意:资料收集、参数选择、等值图勾制、本底与异常的确定,以及评价准则等问题。文中提出了用碳同位素方法判别异常的含油性问题的新尝试,并对若干概念提出了商榷意见。In order to increase the effectiveness of radiometric exploration for oil and gas and wi-dely extend its application, in the present paper some problems such as the deduction andinterpretation of interference factors and measurement data obtained from radiometric ex-ploration, evaluation and criteria of the favorable areas, and several concepts are discussed.It suggests that under specific seasonal conditions in the arid area, so long as interferencefactors are overcome in the field work, the quality of measurement results can be guaranteed(with the error of repeated measurement remaining less than 10%) and satisfactory geolo-gical effects will be got. It is indicated that in the processing and interpretation of datafrom radiometric exploration for oil and gas, much attention must be focused to the follo-wing aspects: collection of information, selection of parameters, drawing of contour maps,determination of background and anomalies and evaluation criteria. In addition, new attempt is presented to use the carbon isotope method for the discrimination of anomalieswith oil possibility, and several other concepts are also discussed in this paper.
