摘要:
针对静态手段判别储集类型的局限性，以试井、酸压、试采等动态响应资料为主，结合地震、测井、钻录井等静态资料，建立了孔洞型储层、裂缝孔洞型储层和洞穴型储层的动静态判别标准，形成了从静态特征、试井特征、酸压曲线、试采特征四个方面判别缝洞型碳酸盐岩储层类型的方法。C井为塔里木盆地奥陶系鹰山组碳酸盐岩油藏上一口评价井，该井钻井过程中有放空、漏失，地震解释为串珠反射，测井解释为裂缝孔洞型、孔洞型；酸压停泵压降曲线呈管流特征，停泵井底压力接近地层压力，酸压判断为洞穴型储层；酸压后压力恢复试井双对数曲线为多缝洞特征；累计产油量与累积压降曲线为多直线段，判断为沟通多个洞穴的洞穴型储层。采用本文方法综合判断，该井为洞穴型储层，与静态认识基本一致，验证了该方法的可靠性，为开发技术政策的制定提供可靠依据。
Abstract:
Due to the limitations of static methods in identifying the reservoir types, this paper used dynamic data (such as well test, acid pressure, and test production) and static data (such as seismic, logging, drilling and mud logging data) to determine the dynamic and static reservoir identification standard for vuggy reservoir, fracturedvuggy reservoir and cavernous reservoir. Meanwhile, an identification method for fracturedvuggy reservoir was also established based on the four aspects of static characteristics, test characteristics, acid pressure curves, and test production characteristics. This paper gives an example of an appraisal well (Well C) in the carbonate reservoir of the Yingshan Formation of the Ordovician system in the Tarim Basin. Drilling break and leakage happened in this well while drilling. The seismic data show that it is a ‘ball chain’ reflector, and logging interpretation result are fracturedvuggy reservoirs and cavernous reservoirs. Moreover, the pressure decline curve after the acid fracturing is characterized by the pipe flow characteristics and the bottom pressure is close to the formation pressure, both of them indicate the reservoir type is cavernous reservoir. After the acid fracturing, the pressure recovers. The double logarithmic curve of the testing is the characteristics of the multifractured vuggy reservoir. Since the cumulative oil production and cumulative pressure drop curves are multistraight features, it is considered that the reservoir type is a cavernous reservoir and is in communication with each other. The results of reservoir types obtained by using the criteria and methods established in this paper are basically consistent with the static understanding, which verifies the reliability of the method and provides a reliable basis for the development technical plan.
