| 摘 要： | 塔河油田缝洞型油藏主要的储集体空间类型为溶蚀的裂缝及大型的溶洞,连通关系极其复杂,70％的钻井需要酸压才能投产.为进一步沟通远井地带的缝洞储集体,室内模拟及现场监测结果表明,超大规模酸压技术能够提高造缝长度,沟通井眼远处的储集体.通过多口井的研究及现场试验,在油气富集带上具有明显的地震反射异常,生产过程中供液不足的井进...

| Abstract: | Most types of reservoir body space are corroded fissures and large carvens,and the connected components are extremely complex.Hence,70% wells request acid fracturing before they are put into production.To further link up reservoir bodies far away from the wellbores,lab simulation and field trials were made.The simulation and the trials showed extra-large scale acid fracturing can lengthen the fracture initiation and further connect the reservoir body away from the wellbore.The study and tests on many wells ... |
