【摘要】：水平井钻井主要是以提高油气产量或提高油气采收率为根本目标,已经投产的水平井绝大多数带来了十分巨大的经济效益,浅薄油层水平井钻井技术的发展为提高勘探效果,提高油气藏采收率开辟了一条崭新的途径。通过水平井现场施工的分析,可以总结出浅薄油层水平井钻井技术应该注意的问题。再结合大量的调研,完善该区块水平井技术的应用,得出一套切实可行的方法。在以后浅薄油层水平井钻井技术与应用中,提供理论依据。本文分析和研究了浅薄油层在随钻过程中可能出现的问题,并结合实际施工,提出相应的解决方案。通过防碰扫描方法分析,并提出应注意的事项解决了防碰绕障的问题。从地质、工程方面入手,得出浅薄油层入靶防止脱靶的方法措施。对于水平井卡钻,我们分析了各种可能出现的隐患,提出了一系列的解决办法。而LWD的应用则帮我们顺利解决了提高油层钻遇率等问题。
[Abstract]:The basic goal of horizontal well drilling is to increase oil and gas production or oil recovery. Most of the horizontal wells that have been put into production have brought great economic benefits. The development of horizontal well drilling technology in shallow reservoir is to improve the exploration effect. Improving oil and gas recovery opens up a new way. Through the analysis of horizontal well field construction, the problems that should be paid attention to in horizontal well drilling technology of shallow reservoir can be summarized. Combined with a large number of investigations, the application of horizontal well technology in this block is improved, and a set of feasible methods are obtained. In the future shallow reservoir horizontal well drilling technology and application, provide the theoretical basis. This paper analyzes and studies the problems that may occur in the process of drilling shallow oil layers, and puts forward the corresponding solutions combined with the actual construction. Based on the analysis of the method of anti-collision scanning, the problems of anti-collision and anti-collision are solved. From the geological and engineering aspects, the methods and measures to prevent the missed target in shallow oil reservoir are obtained. For horizontal well drilling, we analyze all kinds of possible hidden dangers, and put forward a series of solutions. The application of LWD helps us solve the problem of increasing drilling rate.
