0.引言在侧钻施工中,固井一直是施工中的一个关键工序,不合格的固井质量将会给后期井的生产带来诸多麻烦甚至报废,因此提高固井质量是一个刻不容缓的问题。库图尔哲别油田开采已经近五、六十年的历史,由于当地没有进行合理的采注措施,亏空比较严重。我们在施工早期没过多注意这些方面,加上没有专业的固井设备,固井质量比较差,结果导致下入套管正常寿命在1-2年左右。后期逐渐提高了固井质量,使固井质量合格率由2006年的85%到2010年的95%。本文详细介绍了目前胜利油田土库曼油井项目施工的小井眼侧钻固井状况和影响固井质量的因素,对固井现场注意事项和消减措施做了相应的说明,并提出了下步的发展方向。
0. Introduction In the sidetrack construction, cementing has been a key process in construction. The unqualified cementing quality will bring a lot of trouble or even scrapped the production of the late well. Therefore, it is an urgent issue to improve the cementing quality . Kuturhegan Do not oil field mining has been nearly five or sixty years of history, due to the local mining measures are not reasonable, the deficit is more serious. We did not pay much attention to these aspects early in the construction, coupled with no professional cementing equipment, cementing quality is relatively poor, resulting in the normal life of the casing into 1-2 years. The latter part of the cementing quality has been gradually improved so that the cementing quality pass rate from 85% in 2006 to 95% in 2010. This paper introduces in detail the conditions of the wellbore side-hole drilling and the factors that affect the well cementing quality in the construction of the Turkmen oil well project in Shengli Oilfield. The precautions and elimination measures of the well cementing site are explained correspondingly, and the development direction of the next step is proposed .
