红台地区是典型的低压低渗区块,钻井面临着泥浆漏失,地层污染问题。试油工作同样也面临着压井液漏失、射孔后排液难等情况。试油过程中,面临着如何优化试油工艺技术,减少地层污染,提高试油效率,尽快取得准确的试油层位的认识等诸多要求。本文旨在对目前对红台区块进行的一些试油工艺优化情况所取得的一些效果进行总结,提出针对红台区块低压低渗油藏如何开展进行下一步试油工艺,进行探讨形成一套适应红台地区的可行性试油工艺方案。
Hongtai area is a typical low-pressure and low permeability block, drilling is facing mud loss, formation pollution. Oil test work is also facing the loss of fluid killing, drainage and other difficulties after perforation. In the process of oil testing, there are many requirements such as how to optimize oil testing technology, reduce formation pollution, improve oil testing efficiency and get accurate oil testing formation as soon as possible. The purpose of this paper is to summarize some of the results obtained from the current oil-refining process optimization of the Hongtai block, and to propose how to carry out the next oil-testing process for the low-pressure and low-permeability reservoirs in Hongtai block. Set to adapt to Hongtai feasibility test oil process program.
