东胜气田什股壕地区压裂试气结果表明部分井盒1层存在上气下水现象,有效控制压裂裂缝高度是确保施工成功和有效的关键。本文在分析影响裂缝高度各种因素的基础上,结合东胜气田的工程地质特征,采取了多种控缝高技术对策,现场应用效果和井温测井结果均表明缝高都得到了有效控制,说明目前采取控缝高技术是可行且有效的。
The result of fracturing test in Donghai gas field and even trench show that there is gas-bearing phenomenon in the first layer of well casing. Effective control of fracture height is the key to successful and effective construction. Based on the analysis of various factors that affect the fracture height and the engineering geological characteristics of Dongsheng gas field, a series of high-tech measures for seam control are adopted. The field application results and well logging results show that the seam height has been effectively controlled , Indicating that it is feasible and effective to adopt the high-tech of seam control.
