流体录井技术在惠州油田的应用

The Application of Fluid Logging Technology in Huizhou Oilfield

摘要: 流体录井技术与常规气测录井相比具备定量恒温、组分多、精度高、范围广等特点，能够克服海上深水录井作业面临的隔水导管长、井口返出温度低、脱气效率低等问题，保障了气测录井数据能够真实、准确地反映地层含烃丰度。以惠州油田为例，在统计惠州油田24口流体测量数据的基础上，建立了烃比值法图版、计算全烃–流体类型图版以及C₁、iC₄、nC₄、iC₅、nC₅、C₆、C₇、C₇H₁₄等综合参数异常倍数评价标准。结合现场实例分析，综合解释符合率达到87%。

Abstract: Compared with conventional gas logging technology, the fluid logging technology was characte-rized by quantitative constant temperature, multi-compositions, high precision and wide ranges, it could avoid the problems of long risers in offshore deep logging operations, low flow back temperature in wellhead and low efficiency of degassing, which could ensure the true data obtaining from gas logging and accurately reflect hydrocarbon content in formation. By taking Huizhou Oilfield for example, on the basis of statistics of fluid detection data of 24 wells in Huizhou Oilfield, the chart board of hydrocarbon ratio method and the chart board for calculating the total hydrocarbon-fluid type and the criterion for evaluating the abnormal multiples of synthetic parameters such as C₁, iC₄, nC₄, iC₅, nC₅, C₆, C₇ and C₇H₁₄ are established. Combined with field case analysis, the coincidence ratio of integrated interpretation is 87%.
