侧钻井技术作为油田开发中应用最广泛的深基础技术,不仅可以实现充分的利用地质,节约建井费用,还可以对工程报废油水井实现再利用。但是由于侧钻井技术自身的局限性,事故时有发生。由于侧钻井投入低、收效高的特点,青海油田的开发充分运用了侧钻井工程技术,在此给侧钻井的施工带来了良好的实例。本文对侧钻井技术进行了分析,探讨了事故发生的原因,并提出了相应的事故预防与处理措施。
Side-drilling technology, as the most widely used deep foundation technology in oilfield development, can not only make full use of geology, save the cost of well construction, but also recycle the used oil and water wells. However, due to the limitations of lateral drilling technology, accidents have occurred. Due to the low input and high efficiency of lateral drilling, the development of Qinghai Oilfield fully utilizes the engineering technology of side drilling and brings a good example to the construction of side drilling. This paper analyzes the side drilling technology, explores the causes of the accident, and puts forward the corresponding accident prevention and treatment measures.
