杜48块杜零组油层分布不稳定,对比主力油层组油藏发育较差,基本未动用。区块进入吞吐后期,开发矛盾日益突出,针对杜48块杜家台杜零组油层精细油藏描述研究,依据岩性组合、电测曲线形态、旋回组合等特点,考虑到沉积演变的连续性和地层厚度变化及油水组合的合理性,利用油藏精细地质建模技术,分析杜零组油层发育程度、油层连通对应情况及剩余油分布状况,以层位优化、注汽参数优化、井点选择优化为原则,试采杜零组油层,初期获得较好的效果,并进一步部署水平井,实施挖潜。
Du 48 blocks Du zero formation distribution instability, compared to the main reservoir reservoir development is poor, the basic did not use. According to the characteristics of lithologic assemblage, electrical test curve shape and cycle combination, taking into account the continuity of sedimentary evolution And strata thickness variation and the rationality of oil-water combination, using the reservoir fine geologic modeling technology, the paper analyzes the development degree of Duzao reservoir, correspondence of oil reservoir and the remaining oil distribution. Taking the optimization of horizon, parameters of steam injection optimization, Select and optimize the principle, the trial Du-zero reservoir, early to obtain better results, and further deployment of horizontal wells, the implementation of tapping potential.
