面孔斜6井位于渤海湾盆地济阳坳陷东营凹陷八面河鼻状断裂带面14区块,是江汉油田部署在八面河油田南区的一口重点预探井,在该井施工中地层中上部地层地层倾角大,易漏、易塌、易斜,确保硬地层取心收获率;下部奥陶系空隙裂缝十分发育,特别容易发生井漏,钻进中可能伴有硫化氢等一系列困难。现场施工人员经过认真分析,制订了合理的技术措施,保证了该井安全钻达设计层位,为该区块后续勘探开发提供了技术借鉴。
The face of Well 6 is located in block 14 of the Bamianhe nose-like fault zone in the Dongying Sag of the Jiyang Depression in the Bohai Bay Basin. It is a key pre-exploration well deployed in the southern part of the Bamianhe Oilfield by the Jianghan Oilfield. In the middle and upper strata of the formation Stratum dip is large, easy to leak, easy to collapse, easy to oblique, to ensure hard formation coring harvest rate; lower Ordovician gap cracks are developed, particularly prone to leakage, drilling may be associated with a series of difficulties such as hydrogen sulfide. After careful analysis, the site construction staff has worked out reasonable technical measures to ensure that the well drilled safely to the design level and provided technical reference for the subsequent exploration and development of the block.
