垦东12区块位于新滩油田东部的海陆过渡带,其中大部分位于0～10m水深海域内。构造上位于垦东凸起东部斜坡带。垦东12井区主力油层为馆陶组和明化镇组。属高孔高渗储层,胶结疏松,易于出砂,本地区下辖油井103口,其中51口为高原机井,48口为直线电机井,本区油井多为大斜度定向井,本区块自投产以来主要采用了高原机+连续杆+旋转井口和磁悬浮电泵+直线电机两种举升方式。自投产至今,原磁悬浮泵井中已有9口井因为注汽等原因转为高原机井。垦东12区块2011年平均躺井率为5.38%。在2012年1季度躺井较多,占躺井数的57.69%,自2012年4月开始,针对躺井原因进行了细致的分析,采取了针对性的对策,取得了良好地效果,截至目前,年平均躺井率降低为2.53%。 Kendong Block 12 is located in the eastern part of the Xin Tan oil and gas transition zone, most of which located 0 ~ 10m water depth of the sea. It is located on the east slope of Kendong convex. Key reservoir of Kendong 12 well is Guantao group and Minghua group. It is a high-porosity and high-permeability reservoir with loose cementation and easy sand production. There are 103 oil wells under its jurisdiction in the area, of which 51 are plateau wells and 48 are linear motor wells. Most of the wells in this area are highly inclined directional wells. Since the block has been put into operation, it mainly adopts two kinds of lifting methods: plateau machine + continuous rod + rotary wellhead and maglev pump + linear motor. Since it was put into operation, 9 wells in the original magnetic levitation pump well have been converted to plateau wells due to steam injection and other reasons. Kendong 12 blocks in 2011 the average rate of 5.38% well. In the first quarter of 2012, more wells were laid, accounting for 57.69% of the number of wells. Since April 2012, we have conducted detailed analysis on the causes of laying wells, and have taken targeted measures and achieved good results. As of now, , The annual average rate of laying down to 2.53%.
