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。
Due to the strong heterogeneity of underground karst development and distribution, the filling degree of ancient caves and the complex and fluid nature of fluid, the effectiveness evaluation technology of cave reservoir has become a major technical difficulty in well logging evaluation. Correct evaluation of filling and filling of caves is the key to judge its effectiveness. By analyzing the response characteristics of cofferdams with different filling degree and different fillings on conventional well logging curves, electrical imaging and array acoustic images, a method for evaluating the validity of cavernous carbonate reservoirs is proposed. Combined with drilling, well logging , Well testing and earthquakes and other identification marks, the type and level of the reservoir were divided.
