哈拉哈塘油田碳酸盐岩储层试井特征分析

Well Test Curve Analysis of Carbonate Reservoir in Halahatang Oilfield

通过对近4年来哈拉哈塘油田59口压力恢复试井资料整理分析,结合静态资料及生产特征,初步将哈拉哈塘油田储层渗流介质分为视均质型储层、双重介质型储层和裂缝型储层三类,同时根据碳酸盐岩多变的缝洞组合关系,分为三种缝洞组合模型:串珠型(缝、缝+洞、洞+缝、串珠)、复合型和干扰型。对具有类似特征的试井资料选择合适的解释模型,得到准确的储层信息及了解油藏模型,为后期合理的开发措施提供依据。

Through analysis of pressure build up testing data in 59 wells during nearly 4 years of Halahatang oilfield,combined with dynamic and static data and production features,the percolation medium are divided into three types: as the homogeneous、dual porosity and beadsshaped reservoir. According to the changes of carbonate fracture cave combination model,it is divided into three types which are beads-shaped model( fracture、fracture + vug、vug + fracture、beads-shaped) 、composite model and interference model. Selecting the proper interpretation model from similar well test data to obtain accurate reservoir information provides a reference basis for later reasonable development measures later.
