油田勘探开发工程声-振动生物效应统计特征研究

Study on statistical characteristics of acoustic-vibration biological effect in oilfield exploration and development

油田勘探开发过程中,经常遇到由于物探爆破、钻井施工、大修作业等产生噪动,对周围民房或农民家禽、家畜等产生一定影响的现象,从而引发工农纠纷,影响油田勘探开发生产的正常运行.为了指导油田勘探开发科学生产施工,尽量减少对家禽、家畜等养殖以及周围环境的振动影响,开展了油田勘探开发工程声-振动生物效应统计特征研究.文中通过对油区19个自然村庄的实地调查,分别分析了油田勘探开发工程中钻井作业、物探放炮、大型载重卡车等作业所产生的声-振动生物效应特征及不同施工作业对周边居民和动物的影响,结果表明钻井作业和连续的间断性物探放炮对周边环境内某些敏感性较高动物的生理性负面影响具有不可忽视的生物学意义.

The dynamic noise induced by geophysical prospecting blasting,drilling,overhaul operation is often encountered in the process of oil exploration and development. The dynamic noise have a certain impact on the surrounding houses or poultry and livestock.So as to cause the dispute of workers and peasants,and affect the normal operation of oilfield exploration and production. In order to guide the oilfield exploration and development and minimize the vibration effect to the poultry, livestock and surrounding environment,the study on the statistical characteristics of acousticvibration biological effects are carried out. In this paper,through the investigation of the 19 natural villages,the acoustic-vibration biological effect characteristics induced by drilling, geophysical blasting and large trucks are analyzed respectively. The results show that the physiological negative effects of some sensitive animals induced by drilling operation and continuous intermittent geophysical blasting cannot be ignored.
