随着勘探程度的不断加深,油气勘探对象日益复杂,控制投资的压力越来越大。钻井作为勘探开发过程中的重要环节,其费用占勘探开发投资的60%以上,而钻井的井身结构是影响钻井费用的主要因素之一。通过几年的实践,在保证钻井安全的前提下,对钻井的井身结构进行了优化、简化,并对其配套技术进行了研究,使得大港小集油田的钻井经济技术指标较以往大幅度改善,降低了油田勘探开发的综合成本。
With the continuous deepening of exploration, the object of oil and gas exploration is increasingly complicated, and the pressure to control investment is increasing. As an important part of exploration and development, drilling costs account for more than 60% of the investment in exploration and development, and the well structure of drilling is one of the main factors that affect drilling costs. Through several years of practice, under the precondition of ensuring drilling safety, the well structure of drilling has been optimized and simplified, and its supporting technology has been studied, which has greatly improved the economic and technical indicators of drilling in Dagang Xiaoji Oilfield compared with the past , Reducing the overall cost of oil exploration and development.
