【摘要】 由于地下溶洞发育及分布的非均质性极强,古洞穴的充填程度及流体性质的复杂多变,使得洞穴型储层有效性评价技术成为测井评价的一个主要技术难点。而正确评价洞穴的充填物和充填情况是判断其有效性的关键。通过分析不同充填程度、不同充填物的洞穴在常规测井曲线、电成像和阵列声波图像上的响应特征,提出了洞穴型碳酸盐岩储层的有效性评价方法,并结合钻井、录井、试井及地震等方面的识别标志,对储层类型和级别进行了划分。更多还原

【Abstract】 As undrground cave development and distribution has strong heterogeneity,complexity and variety of the filling degree and fluid property of ancient caves make the validity evaluation technology for cave reservoirs difficult in logging evaluation.The fillings and filling condition of caves are the key of judging validity.Through analyzing the response characteristics of differ filling degree and differ fillings of caves in conventional electrical imaging logging and array acoustic logging image,the evaluation method of validity for cave carbonate reservoirs is proposed.The reservoir types and grade are divided with combination of drilling,well logging,well testing and seismic data.更多还原
