| 摘 要： | 研究区庄36区自喷井分布密集,以正方形井网为例,应用"动静结合-判别分析"的方法,总结了自喷井自喷的原因。砂体连通性为射孔对应,同种成因砂体相互连通;物性条件为物性相对较好,满足判别函数;压力为正方形井网油井地层压力大于最小自喷压力15.17 MPa;井距为正方形井网满足极限井距414.88 m。通过自喷井自喷的原因分析,发现人为实现自喷的可能性;但是地下地质条件复杂,认识存在不足,并且仍需要不断加深。为此实现自喷只是一种理想模式,但也为自喷井的研究提供了一定的思路。

| Abstract: | Zhuang36 area is rich in flowing wells. Take square well nets as an example, through discriminant analysis, integrate dynamic and static, summarize the reasons for flowing wells. Interconnection of sand -body: perforation corresponding, same sandbody connect each other; Physical property: property are relatively good, meet the discriminant function; Pressure: formation pressure of square well nets is greater than 15.17 MPa; Well spacing: well spacing of square well nets is less than 414.88m.Through the cause analysis of flowing wells, manual achieve natural flow is possible, but because of the complexity of underground geological conditions, the inadequacy of understanding ,achieve natural flow is an ideal mode, but this article provide certain research approach for flowing wells. |
