红外光谱录井解释方法在长庆区域油探井的应用
|
摘要
从红外光谱录井技术原理及技术特点着手,通过对近几年长庆区域红外光谱资料的分析研究,结合鄂尔多斯盆地油藏特征及储集层岩心物性分析、试油等资料,建立了适合长庆区域油藏特征的储集层流体性质解释评价方法。纵向上以全烃曲线的高低结合气体比率变化情况定性识别未知储集层所含流体的性质,建立了录井储集层流体性质定性解释标准,同时优选了红外光谱录井敏感参数,建立了储集层能量系数Q与重烃指数CHS定量解释图板,两种解释方法相结合显著提高了红外光谱气体录井在长庆区域油探井储集层解释评价中的实用性和准确率,形成了一整套较为可靠的资料解释评价方法。经过大量油探井数据验证,在完成的83口井中,储集层油水层解释符合率高达80%以上。该方法解决了长庆区域油探井快速钻井条件下油气层识别评价的技术难题,具有较好的推广价值。
Based on the principle and characteristics of infrared spectral logging technology,the infrared spectrum data of Changqing region in recent years were analyzed and studied.Combining with the reservoir characteristics,the physical property analysis of reservoir core,well testing and other data in Ordos Basin,an interpretation and evaluation method of reservoir fluid properties suitable for oil reservoir characteristics in Changqing region was established.Vertically,the properties of the fluid contained in the unknown reservoirs can be identified qualitatively by the peak value total hydrocarbon curve and the changes of gas ratio,and the qualitative interpretation standards for fluid properties of mud logging reservoirs were set up.At the same time,the sensitive parameters of infrared spectral logging were optimized,and the quantitative interpretation chart of reservoir energy coefficient(Q) and heavy hydrocarbon index(CHS) was established.The combination of the two interpretation methods significantly improves the practicability and accuracy of infrared spectral gas logging in reservoir interpretation and evaluation of oil exploration wells in Changqing region.A complete set of reliable data interpretation and evaluation methods have been formed.Verified by a large number of data from oil exploration wells,the interpretation coincidence rate of oil and water layers in the reservoirs of 83 completed wells is over 80%.This method solves the technical problem of hydrocarbon reservoir identification and evaluation under the condition of rapid drilling of oil exploration wells in Changqing region,and has good popularization value.
