双侧向测井裂缝参数解释方法的应用

Fracture Parameter by DLL Interpretation and Its Application to Carbonate Rock

碳酸盐岩裂缝性储层空间类型多、变化大,裂缝参数的定量评价难度大。为了充分利用常规测井资料有效地定量评价裂缝参数,在前人对双侧向测井响应的数值模拟及反演方法研究基础上,建立了一套裂缝性储层参数解释模型来估算塔中地区良里塔格组颗粒灰岩段裂缝参数,并将其结果与岩性、岩心及试油资料对比检验,得到了充分的验证,说明该套估算裂缝参数的方法在该地区的可行性和有效性。

For carbonate fractured reservoir, its space is characterized by different types and large variation. So, a quantitative evaluation to fracture parameter is very hard. In this study, some previous researches on both numerical simulation and inverse method of DLL response are firstly summed up; and then a series of parameter interpretation models for fractured reservoir are developed to estimate the fracture parameter of grain limestones in Lianglitage Formation, Central Tarim Basin; at last, the estimated results are compared with some lithological, core and well-testing data. Result shows that this method to estimate fracture parameter is effective and its application to Central Tarim Basin is feasible.
