利用气测录井简易参数法判别油、气、水层

气测录井现场解释评价常用且比较成熟的经验统计法有烃组分三角形图解法、皮克斯勒解释图板法、烃类比值法（3H法）等，由于不同井场的地下地质和地面环境因素不尽相同、钻井工程参数的差异和解释方法的局限性，各种方法的解释符合率均有一定程度的差异。从提高解释符合率以及简便、快速发现并判别油、气层的角度出发，分析了应用气测录井全烃、异常倍数和重烃相对含量判别储集层油气水状况的理论依据，给出了利用该3项参数的判别标准，结合实例分析了不同条件下的判别原则，同时指出了该方法的局限性。通过103个油、气、水层的判别实例归纳分析，表明这种方法简便、可行，符合率相对较高，具有一定的推广应用价值。

A simple method for the determination of water-oil-gas layer with gas logging parameters

The common and matured experience statistical methods for on-site gas logging interpretation and evaluation include hydrocarbon component triangle diagram method, Pixler interpretation chart method and hydrocarbons rationing method(3H).The difference in underground geologic and ground environmental factors of different well sites, and that of drilling engineering parameters and limitation of the various interpretation methods,will bring about a certain discrepancies in the coincidence rate of different inte...
