丰富的天然气资源存在于苏里格气田中,但因为储层低孔低渗负压,开采的结果一直欠佳。由于这一原因桃7-3-4H井设计为长水平段水平井,并且通过分析其轨迹控制、井下摩阻、井身质量等难点;使用井眼轨迹控制措施、摩阻和扭矩监测、以及良好的钻井液性能,并配合高效PDC钻头和地质导向技术;该井完钻井深5561m,水平段长度1950m,实钻周期75.75d,多项指标取得了较好的效果,最重要的是很大程度的提高了钻井效率。
Rich natural gas resources exist in the Sulige gas field, but the result of mining has been poor due to the low porosity and porosity of the reservoir. For this reason, the peach 7-3-4H well was designed as a long horizontal horizontal well, and through the analysis of its trajectory control, downhole friction, well-bore quality and other difficulties; the use of well trajectory control measures, friction and torque monitoring, and Good drilling fluid performance, and with high efficiency PDC bit and geosteering technology; completion of well drilling depth of 5561m, the horizontal length of 1950m, the actual drilling cycle 75.75d, a number of indicators have achieved good results, the most important is very large The degree of drilling efficiency.
