塔河碳酸盐岩油藏试井解释新技术应用

Application of Well-Test New Technical Interpretation in TaHe Carbonate Reservoir.

塔河奥陶系碳酸盐岩油藏是非均质性、各向异性特点十分突出的溶蚀缝洞型油藏。对该油藏在常规试井解释方法的基础上尝试了有限元数值试井,从空间和时间上对油藏的全部生产过程中压力的动态进行了准确描述,并在一定数量的测试井中得以应用,研究认为利用此方法能够实现对油藏内部不同区域渗流条件和流体渗流特征的精细刻画,可以在塔河油田奥陶系碳酸盐岩缝洞型油藏进行推广应用。

The Tahe ordovician reservoirs is the seam hole carbonate rocks reservoirs. Based on conventional well testing interpret method finite element numerical well test evaluation module is tried and all the process while producing are accurately described in space and time. Study shows that this method can be used to accurately describe the transfusion condition and the fluids' property in different areas in inner section of the reservoir and can be applied in Ordovician petroleum deposit in Tahe oilfield.
