塔里木盆地哈拉哈塘油田A-B区块二叠系火成岩漏失原因与应对措施
|
摘要
哈拉哈塘油田A-B区块二叠系火成岩频繁井漏,阻碍了提速降本,准确预测漏失位置,可以为优选井身结构及钻井液优化提供技术支持。地质上,利用薄片观察对不同岩性进行了识别;物探上,采用属性提取、曲率、切片等技术手段,将研究区火成岩地震反射特征分为3类:空白相、亚平行相、平行相,不同的地震反射特征具有不同的岩性组合特征。通过漏失井岩性、地震相、漏失位置、漏失量分析,结合裂缝发育特征,认为火成岩空白相裂缝发育段钻井漏失量大,亚平行相的玄武岩顶部易发生少量钻井漏失。布井时需根据火成岩的不同相采取相应的措施,空白相应避免人工压裂;亚平行相需控制泥浆密度。
The Permian igneous rocks in Halahatang Oilfield A-B block lost circulation frequently. The well leakage prevents the drilling from accelerating and reducing the cost. If the location of leaking well can be accurately predicted, we can provide technical support for optimizing well depth structure and drilling fluid. On the geological,different lithology are identified by rock thin-section. Geophysically, using the technical means of attributes, curvature and slice, seismic reflection characteristics of igneous rock in the area could be divided into three categories, blanking phase, sub-parallel phase and parallel phase. Different seismic reflection characteristics have different lithological combination characteristics. By analyzing the lithology of the leaking well, the seismic phase, the lost position and the leakage, combing with the characteristics of fracture, we believed that there are different laws of leakage in different seismic phase. There is a large amount of drilling leakage in the fracture development section of the blanking phase while the top of basalt in sub-parallel phase is prone to a small amount of drilling leakage. It is necessary to take corresponding measures according to the different seismic phase of igneous rocks. In the drilling of Permian igneous rocks, artificial fracturing should be avoided in the blanking phase and mud density should be controlled in the sub-parallel phase.
