Study on the Distribution of Interlayer in Thick Sandy Braided River under Large Well Spacing—A Case of C Oilfield in Bohai Sea

Using core, logging and other data, combined with field outcrop deposition, this paper studies the sedimentary genetic types and sedimentary stages of thick sandy braided river interlayer in C oilfield, and divides two stages of interlayer and three single-stage braided flow zones. On this basis, geostatistical inversion constrained by logging and discerning River quantitative knowledge base is carried out to predict the distribution range of the main interlayer in the two phases. The production performance test of the blind well and horizontal well shows that the coincidence rate of the prediction results of interlayer with thickness > 1.5 m is 75%. The research shows that the first stage is the main interlayer, mainly composed of mudstone of flood plain origin, with an average thickness of 2.1 m and relatively stable distribution. Based on the interlayer prediction results, the small layer of composite sand body 1 forms a residual oil enrichment area in the high part of the structure due to the wide range of interlayer shielding in the lower part, which is a favorable area for adjusting and tapping potential.

Sensitivity Analysis of Offshore Sandstone Reservoir—A Case Study of an Oilfield in the Western Bohai Sea

X oilfield is located in the Western Bohai Sea. During the water injection development process, the oil well productivity continued to decline. The effect of water injection and oil increase is poor. This time, by analyzing the sensitivity of the reservoir, the damage mode of the reservoir is analyzed, the reasons for the poor water injection effect are obtained, because of strong water sensitivity, medium to strong stress sensitivity, and the corresponding measures and suggestions are put forward, such as greater than 4500 mg/l of the salinity of injected water, timely supplement formation energy. Provide basis for the development of similar oil fields.

夏枯草开音合剂治疗血瘀痰凝型声带白斑伴轻中度异型增生的临床观察

目的 观察夏枯草开音合剂治疗血瘀痰凝型声带白斑伴轻中度异型增生的临床疗效。方法 将2019年1月~2022年1月上海市中医医院的86例声带白斑患者随机分为治疗组和对照组,治疗组采用夏枯草开音合剂治疗,每次25m L,每日2次;对照组采用金嗓散结胶囊治疗,每次2粒,每日2次。治疗时间均为8周。采用症状体征积分评价临床疗效,用VHI量表、基频微扰、振幅微扰、谐噪比、MPT评价主客观嗓音功能。结果 实际完成79例,治疗组40例,对照组39例。治疗组总有效率87.5%,高于对照组66.67%(P<0.05);两组治疗后症状体征积分均下降,治疗组总积分低于对照组(P<0.05);治疗后两组嗓音功能均得到改善,治疗组基频微扰、振幅微扰低于对照组,谐噪比高于对照组(P<0.05)。结论 夏枯草开音合剂治疗血瘀痰凝型声带白斑伴轻中度异型增生疗效确切,在缓解声嘶、缩小白斑面积和声门裂宽度、改善声音粗糙嘶哑程度、以及恢复声带闭合运动方面,疗效均优于金嗓散结胶囊。

从“肠胃不通,九窍不利”论治鼻鼽

脾胃为调节人体情志之机要,肠道为人体阴平阳秘之所在,胃肠道提供的水谷精微是人情志活动的物质动力。中焦气机的升降相宜是人精神内守的必要条件。鼻鼽病等耳鼻喉科疾病具有很强的主观性。若患者肠胃不通,九窍不利,中焦代谢失衡,可引起患者情绪紊乱,致使患者主观症状增加,引发鼻鼽病。治疗鼻鼽病应建中焦、资宗气、行血养神,方以四君子汤加减,针刺宜取阳明经。此外,治疗鼻鼽病不应以治愈为目的,而应将重心转移到改善患者的生活质量上来,重视饮食、压力、情绪等因素对疾病发生发展的影响并适当干预,对提高鼻鼽病患者的生活质量大有意义。
