吐哈油区稀油油藏开发实践及技术攻关方向

吐哈油区稀油油藏经历30 a的开发与实践,形成了一系列稀油油藏高效开发的方法。由于主力油田稀油油藏多为特低渗—低渗油藏,储集层非均质性强,低含水开发阶段采用强采强注面积井网,采油速度较高,开发效果较好;中—高含水阶段及时采取了井网加密等对策,短期为减缓递减、稳定产量发挥了重要作用。但油田开发初期的强注强采也影响了主力层的驱油效率和采收率,尤其是进入特高含水期,无效注水循环严重,套损井和停产井增多,造成地层压力保持水平低,常规措施治理难度大,稀油油藏开发进入低速低效开采阶段。为了从根本上提高开发效果,积极开展注气提高采收率、纳米微球复合调驱及转变渗流场等室内研究和矿场先导试验,取得了初步效果,形成一系列多元类型油藏分类提高采收率和提高开发效果的技术。随着这些技术的进一步发展和应用,吐哈油区稀油油藏自然递减率有望由19.8%逐步降至11.0%,采收率将提高2.00%~3.00%。

鄂尔多斯盆地致密油水平井注水吞吐开发实践——以延长组长7油层组为例

针对致密油藏长水平井自然能量开发后期如何补充能量的难题，在致密油藏注水吞吐采油机理、可动油定量评价和矿场试验评价的基础上，提出了水平井注水吞吐的选井条件和技术政策：①初期产量较高、含水较低、有一定稳产期的水平井实施注水吞吐效果较好。②从经济性和储层非均质性两方面考虑，若水平井单段人工裂缝破裂压力差异小，则采用经济、操作简单的笼统注水吞吐方式；若水平井单段人工裂缝破裂压力差异较大，采用分段注水吞吐方式能够较好提高段间注水波及面积，缺点是成本较高。③鄂尔多斯盆地延长组长7油层组致密油自然能量开发转注水吞吐补充能量时机为地层压力保持水平降到原始地层压力的60%；注水吞吐注水后地层压力保持水平达到原始地层压力的110%；单段注水速度为10~20 m³/d；焖井时间为10~13 d （1 000 m³注水量）；开井后水平井百米日产液量为1.5 m³/d。对鄂尔多斯盆地延长组长7油层组的50多个井组开展了致密油水平井注水吞吐试验，有效井组的比例达到了约70%，平均井组增油量为610 t，取得了较好的实施效果。

Technology enhanced learning of quantitative critical thinking

A Quantitative Critical Thinking (QCT) software tool was developed in this study to facilitate students’ learning of quantitative critical thinking via repeated practice by chemical engineering students reading a core module called fluid-solid systems. The software tool generated detailed calculation steps to typical engineering design problems encountered in this module that contained weaknesses, flaws or even errors. Students utilized the software tool to practice identifying these weaknesses, flaws or errors in the design solutions and then present a better or correct design by applying the concepts and knowledge acquired in the module. Since the QCT software tool was built upon an existing design software tool that was able to generate the correct, detailed design calculation steps to design problems, students were able to check their own design calculations against those presented by the software tool during this second learning step, thereby engaging in and learning quantitative critical thinking via a repeated practice approach. The software tool was successful in enhancing the performance of second-year undergraduate students in solving a question that required quantitative critical thinking in the final examination of the module. The average percentage scores achieved by students for the question who reported higher frequencies of usage of the software were generally higher than those who reported lower frequencies of usage or did not utilize the software tool throughout the semester.
