杏北开发区A区块是水平井三元复合驱试验区块,2008年开展了井间示踪剂检测试验,采用直井注直井采、直井注水平井采、水平井注直井采和水平井注水平井采四种试验方式.试验结果揭示了厚油层砂体内部连通关系,同时也为精细储层描述提供了重要的第一手资料.原平面沉积微相研究中,废弃河道微相平面组合有一定预测性,结合示踪剂资料精细、准确修改试验区平面相展布,解决示踪剂试验结果与砂体认识矛盾,体现了地质研究中“动静结合”的思想.
Block A of Xingbei Development Zone is a horizontal well ternary compound flooding pilot block. In 2008, cross-well tracer testing was carried out. Vertical well injection, horizontal well injection, horizontal well injection and horizontal well injection Hirai mining four kinds of test methods.The test results reveal the connectivity relationship of the thick reservoir sand body, but also for the fine reservoir description provides an important first-hand information.Original plane sedimentary microfacies study, the abandoned river microfacies plane combination of Certain predictability, combined with tracer information, fine and accurately modify the plane phase distribution in the test area to solve the contradiction between the tracer test results and the understanding of the sand body, reflecting the idea of “dynamic and static combination ” in geological research.
