Minghuazhen and upper Guantao formation are main oil-bearing series of CB243 heavy oil block in Chengdao oilfield, the block reservoir is characterized by shallow buried depth, weak bonding, great formation permeability grade difference, high clay mineral content, low formation temperature, thin oil layer, bad physical property of crude oil, etc.
由于受当时海上防砂工艺装备的影响和采油工艺技术的限制,CB243区块在投产初期采用挂滤砂管、循环充填防砂工艺以及潜油螺杆泵、电泵带电加热机械采油方式生产,投产后出现油井产能低、不能连续稳定生产、检泵周期短等问题。

补充资料：钚243
分子式：
CAS号：
性质： 243Pu是半衰期为4.98h的β辐射体，经β衰变生成243Am。因243Pu的半衰期短，燃料元件在反应堆中辐照期间，它仅以很低的浓度存在。在辐照元件贮存几周后即消失。
