天然裂缝发育与否,对特低孔特低渗油气藏而言意义重大。钻探取芯资料观察、成像测井资料观察是了解储层天然裂缝发育与否最直接、最可靠的方法。由于油气藏不同部位、不同层段因地应力差异大,天然裂缝发育程度差异很大,上述研究了解天然裂缝发育程度的方法成本太高,研究应用常规测井资料识别单井裂缝发育井段就显得十分必要了。安棚油田深层系应用双侧向测井和补偿声波测井等资料计算、识别单井裂缝发育井段的实践表明,应用常规测井资料计算、识别单井裂缝发育井段的方法是经济可行的。
The development of natural fractures or not, for ultra-low-permeability ultra-low permeability reservoir significance. Observation of drilling coring data and observation of imaging logging data are the most direct and reliable methods for understanding the development of natural fractures in the reservoir. Because different parts and layers of oil and gas reservoirs have large differences in site stress and great differences in the development degree of natural fractures, the cost of the method for understanding the degree of development of natural fractures is too high. Based on the analysis of conventional well logging data, It is very necessary. The application of double lateral well logging and offset acoustic logging to the deep section of Anpeng Oilfield, and the practice of identifying well sections in single well fractures show that it is economically feasible to use conventional well logging data to calculate and identify well sections for single well fractures of.
