【摘要】：随着社会的发展石油在工业、农业、交通以及日常生活的需求与日俱增。已经成为人们赖以生存不可或缺的一种物质。石油开采工作的重要性也就日益彰显出来。所以说石油的勘探开发工作也越发显得重要。而在石油勘探作业中最为重要的则是钻井的速度问题,钻井速度的快慢直接影响到了经济效益,但目前制约钻井速度提高的因素有很多,如何能够大幅度提高钻井的速度就成为了迫切需要解决的问题。这就需要我们着力于钻井技术的优化上,不断的进行创新。本文就石油开采提速增效情况及具体措施的应用效果进行研究,通过对吉林油田伏龙泉区块钻探中遇到的一些实际问题,通过对改进钻头,优选螺杆,优化泥浆,以及预防井下事故等方面较为详细的论述提速的措施和注意事项及收到的效果。本文所述的伏龙泉油气田属于油气分布为大面积的低压、低渗、低产的岩性气藏,位于吉林省农安县与长岭县的交界处,开发难度很大。由于其特殊地质构造,导致钻井过程中遇到的复杂情况增多,钻井速度下降、同时成本增加,这将会直接影响到伏龙泉地区勘探、开发的进程。为了在该区块更好地钻探施工,合理开发地下资源,减少复杂情况及事故,避免由此造成的重大经济损失,我们对该区块已完成井以及典型事故与复杂情况进行了详细的分析,研究其地层特点优选成熟的钻井技术,制定出了一系列切实可行的施工措施,并推广应用到钻井生产中大大提高了该区块钻井速度。本文以类型接近的伏230与伏233井进行比较,在进行技术优化工具优选后伏233井的钻井速度得到了大幅度的增加,同比伏230机械钻速3.73m/h,伏233井平均机械钻速达到了4.33m/h,比伏230年提高了16.1%。同时钻井周期也大幅度缩短,由伏230的钻井井周期58.14天缩减至46.02天。同时在螺杆和钻头的使用上也有大幅度的减少,创造了可观的经济效益。
[Abstract]:With the development of society, the demand for oil in industry, agriculture, transportation and daily life is increasing. It has become an indispensable material for people to survive. The importance of oil extraction is becoming increasingly apparent. Therefore, the exploration and development of oil is becoming more and more important. The most important problem in petroleum exploration is the speed of drilling. The speed of drilling has a direct impact on economic benefits, but there are many factors restricting the improvement of drilling speed. How to improve the drilling speed has become an urgent problem to be solved. This requires us to focus on drilling technology optimization, continuous innovation. In this paper, the situation of increasing speed and increasing efficiency of oil production and the application effect of concrete measures are studied. Through some practical problems encountered in drilling in Fulong Quan block of Jilin Oilfield, and by improving bit, selecting screw and optimizing mud, The measures, precautions and effects of increasing speed are discussed in detail in the prevention of underground accidents. The Fulongquan oil and gas field described in this paper is a lithologic gas reservoir with large area of low pressure, low permeability and low yield, which is located at the junction of Nong'an County and Changling County, Jilin Province, and is very difficult to develop. Because of its special geological structure, the complexity of drilling process increases, the drilling speed decreases and the cost increases, which will directly affect the process of exploration and development in Fulong Quan area. In order to drill in the block better, develop underground resources reasonably, reduce the complex situation and accident, and avoid the great economic loss caused by it, we have made a detailed analysis of the completed well and typical accident and complex situation in this block. A series of feasible construction measures have been worked out, and the drilling speed of this block has been greatly improved by popularizing and applying to drilling production. In this paper, the drilling speed of Fu-233 well has been greatly increased after the optimization of technical optimization tools was carried out by comparing the similar type of Fu-230 well with that of Fu-233 well. The average drilling speed of V233 well was 4.33 m/ h, 16.1% higher than that of 230 years. At the same time, the drilling period was also shortened, from 58.14 days to 46.02 days. At the same time, the use of screw and bit has been greatly reduced, creating considerable economic benefits.
