摘要
塔里木油田克深地区砂岩储层岩性复杂,属于特低孔、低渗油气藏,测井对裂缝识别评价有重要意义。采用分形理论,针对常规测井资料进行处理,得出可靠嵌入空间法进行裂缝识别。该方法在大北克深地区20余口井的实际应用结果表明,与成像资料符合度较高,证明分数维方法识别裂缝切实可行,可在油田致密砂岩储层中推广应用。
The lithology of sandstone reservoir was complex in Keshen Area of Tarim Oilfield,it belonged to low porosity and low permeability oil and gas reservoir,thus well-logging was significance to the evaluation of its fractures.This article adopted fractal theory to study regular well-logging data,which proved reliable space embedding algorithm for fracture recognition.The method is used in more than 20 wells in Dabei-Keshen Area,the result shows that the result is highly consistent with that of imaging data,it demonstrates that fractal method is effective for fracture recognition and can be widely used in the tight sandstone reservoirs in oilfields.
