摘要
油气化探综合异常评价是油气化探测量中最为关键的一环,它关系着一个地区的含油气性评价和远景预测。由于多种原因,过去人们对诸多的化探综合异常仅限于定性评价,而缺乏量的概含。为此,作者应用综合评价指数和模糊数学等多种方法,通过对甲、乙、丙三个典型试验区的研究,证明了该方法的可行性和有效性,取得了良好的地质效果。
Abstract: The appraisal of oil-gas composite geochemical anomalies is the most important key link in oil-gas geochemical survey and has a vital bearing on the evaluation of oil-gas potential and prospective prognosis of an area. In the past, conditioned by various factors, geologists could merely make qualitative evaluation for various geochemical conposite anomalies and, as a result, quantitative data were lacking. To solve this problem, the author has utilied lots of techniques including integrated indices for appraisal and fuzzy mathematics. The researches performed in three typical experimental areas have yielded satisfactory geological results, thus demonstrating the feasibility and effectiveness of these methods.
