乍得潜山油藏裸眼试油技术
|
摘要
乍得潜山裸眼段漏失严重,致使打水泥塞时灰面高度难以控制,封层成功率低,MFE等常规测试工具和抽汲排液测试技术难以满足长裸眼段分层测试和稠油井排液测试。根据乍得潜山油藏裸眼段储层特征及井身结构,形成了潜山裸眼常规试油工艺、长裸眼段试油工艺、裸眼桥塞联合注灰封层上返试油工艺、潜山裸眼稠油试油工艺和潜山裸眼测试工作制度。经BC2-1井应用表明,坐套测裸的NAVI泵+APR工具排液测试求得的流动压力和产量均比较稳定,NAVI泵累计运转1 475 min,产液96.746 m~3,产油90.243 m~3,试油效果显著。该裸眼试油系列技术为乍得潜山油藏评价和开发方案编制提供了有力依据。
The serious mud loss in the open hole interval of Chad buried hill reservoir lead to the difficulty of controlling the gray surface height when the cement plug was used, and the success rate of the sealing layer was low. Therefore, the conventional test tools such as MFE and the pumping and draining test technology were difficult to meet the need of stratified testing and drainage test of heavy oil well in long open hole interval. According to the characteristics of the reservoir and the wellbore structure of the open hole in the Chad buried hill reservoir, some testing techniques for the open hole of the buried hill reservoir have been formed, such as the conventional oil testing technology, the long open-hole oil test technology, oil test technology after cementing the down layer by combination of open hole bridge plug and cementing, buried-hill heavy oil testing technology and buried-hill open-hole testing. The application result of Well BC2-1 shows that the stable flow pressure and productivity can be obtained by the drain testing with NAVI pump and APR tool. The NAVI pump has a total operation of 1 475 min, the production liquid was 96.746 m~3, and the oil production was 90.243 m~3. The testing effect was remarkable. This series of oil testing technology for open hole provided a strong basis for buried hill reservoir evaluation and development planning in Chad.
