高18块为高升油田稠油区块,经历了天然能量、蒸汽吞吐和注水开发三大阶段,目前处于低速开采阶段,2008年以来,在开展精细油藏地质特征研究及水平井优化设计基础上,部署水平井1口,进行该块二次开发试验,并根据油藏自身特点,设计水平井长度、方位等技术参数,有效提高油藏动用程度,最终促使高18块最终采收率有所提高。 The high 18 block is the heavy oil block of Gaosheng Oilfield and has undergone three major phases of natural energy, steam stimulation and water injection development. Currently, it is in a low-speed exploitation stage. Since 2008, based on the study on the geological characteristics of fine reservoirs and the optimization design of horizontal wells , The deployment of horizontal wells 1, the second development of the block test, and according to the reservoir’s own characteristics, the design of horizontal well length, azimuth and other technical parameters to effectively improve the degree of reservoir utilization, eventually led to high 18 final recovery rate improve.
