摘要
近１０年来水平井测井解释在理论成果、解释方法与应用软件方面取得了丰硕成果。归结起来，其研究思路有两个：①以仪器响应的计算机模拟研究为基础，通过制作理论图版寻求合理的解释方法；②以岩石各向异性研究为基础，认为仪器在大斜度井和水平井中的响应异常是由于地层的各向异性引起的。前者偏重于理论上的定性描述，不便在逐点解释中运用；后者虽便于逐点解释却应用条件苛刻，无法很好地考虑井眼、围岩和侵入等环境因素的影响。笔者认为未来的研究工作应以模型井中的仿真实验为基础，才能找到一条既方便又可行的解释方法；同时应加强水平井的地质设计研究。
After 10 year's work, a great success to logging
interpretation of horizontal wells in theory, interpretative method and applied software has been
achieved. To put it in a nutshell, there are two kinds of opinion: the first is based on computer
simulation of sonde response research, trying to find a reasonable method by making charts;
the another based on rock anisotropy study, considering the abnormal sonde response due to
the anisotropy of formation drilled by extendedreach and horizontal wells. The former lays a
particular stress on qualitative theoretic analysis, not to be convenient for data processing on
computer; the latter is easy to process data, but its applied conditions are very strict, difficult to
solve the environment effect such as borehole ,boundary bed and invaded zone. The future
research work must be on the basis of experiments in well models in order to get a convenient
and feasible interpretative method. At the same time, the research work should be strengthened
on geological design of horizontal wells so as to grasp the distribution and extension of oil
formations.
