【摘要】：近年来,水平井钻井技术随着石油工业的发展在全世界得到了越来越广泛的应用,而且国内水平井技术已经相对比较成熟。目前,扎那诺尔油田直井目的层裸露面积相对有限,有效开发油层是必须攻克的难题。扎那诺尔油田早期开发生产井由于底水快速锥进,造成产量锐减,采出程度低,储量动用程度差,适宜部署水平井。本文针对扎拉诺尔油田的实际情况,采用合理的造斜率、优化的井眼轨迹设计和钻具组合,对井眼轨迹控制工具和仪器进行了选型和配套,形成了适合扎拉诺尔油田水平井的井眼轨迹控制技术、地质导向技术和泥浆体系。在做好水平井地质设计和钻井设计的基础上,充分利用随钻测量、随钻测井和录井等资料来确定钻头钻进方向及在目标地层中的位置,以实时调整井眼轨迹,使其尽可能在油层物性较好的部位延伸。水平井的研究为扎那诺尔油田水平井的施工提供了合理可行的地质导向方案,成功地指导了水平井的施工。水平井单井产能与相临直井相比,提高了3倍以上,达到了预期的目标并获得了显著的经济效益。
[Abstract]:In recent years, horizontal well drilling technology has been more and more widely used in the world with the development of petroleum industry, and domestic horizontal well drilling technology has been relatively mature. At present, the exposed area of the target layer in Zananor Oilfield is relatively limited, and the effective development of reservoir is a difficult problem to be solved. Due to the rapid coning of bottom water in the early production wells in Zananor Oilfield, the production rate is sharply reduced, the degree of recovery is low, and the level of reserve production is poor, so it is suitable to deploy horizontal wells. In this paper, according to the actual situation of Zalanor oil field, adopting reasonable slope making, optimized well trajectory design and drilling tool combination, the well trajectory control tools and instruments are selected and matched. The well trajectory control technology, geological guidance technology and mud system suitable for the horizontal well in Zalanor Oilfield are formed. On the basis of the geological design and drilling design of horizontal wells, the drilling direction and position of the bit in the target formation are determined by fully utilizing the data such as while drilling measurement, logging while drilling and logging, so as to adjust the borehole trajectory in real time. Make it extend as far as possible in the oil reservoir where physical properties are better. The study of horizontal well provides a reasonable and feasible geological guidance scheme for horizontal well construction in Zananor Oilfield, and successfully guides the construction of horizontal well. The productivity of single well in horizontal well is more than three times higher than that in adjacent vertical well, and the expected goal is achieved and remarkable economic benefit is obtained.
