摘 要:伴随着国内经济与科技的高速进步,近年来,国民经济发展进步展现出逐步向好的可喜趋势。同时,各行各业的快速发展造成我国对石油资源的使用量愈来愈大。当今时代,为了符合各行各业发展的要求,石油挖掘开采作业工程快速增加。一般来说,在钻井挖掘开采作业时,因为地下石油层的构造相当繁杂,所以针对钻井工程的解决方案的需求相对很高,假如工程技术作业过程存在不规范的情况,很可能造成油井渗漏问题的产生的几率增加。

Abstract: With the promotion of the rapid progress of domestic economy and science and technology, in recent years, the development and progress of the national economy has shown a gratifying trend of gradually getting better. At the same time, the rapid development of various industries has led to the increasing use of oil resources in our country. Nowadays, in order to meet the requirements of the development of various industries, the engineering of oil excavation and exploitation is increasing rapidly. Generally speaking, because the structure of the underground oil layer is quite complicated in the drilling and excavation operation, the demand for the solution of drilling engineering is relatively high;therefore, if there is a non-standard situation in the process of engineering and technical operation, it is likely to increase the probability of oil well leakage problems.
Keywords: drilling operation; preventing well leakage; plugging method; research
前言
油井滲漏弊病频繁发生会导致打井采掘工程作业不能顺利推进,与此同时也是为难油田相关工程技术人员许久的工艺方法方面的困难和安全生产作业隐患。这是由于假如钻井作业进程中产生油井渗漏问题,就可能造成一整套相当严重的后果,不但影响钻井施工作业过程不能顺利推进,扰乱钻井作业计划的既定作业安排,拖延工期,并且还会留下诸多安全隐忧,严重的话,会对相关现场工作人员的人身财产安全造成严重的威胁。
1 钻井挖掘开采作业中油井渗漏的主要原因
1.1 钻井挖掘开采作业中油井渗漏的条件
在钻井挖掘开采作业进程时,鉴于地下岩石层构造中隐藏着数量繁多的沟槽和小洞穴,故此打井溶液和泥浆等溶液和杂质渗漏到岩石层内部的概率大幅度增加。……
