过去,对于碳酸盐岩气田的开发,在储量未搞清的情况下,根据井口产能定产,致使部分气井定产偏高,气田气井采气速度很快上升。过高的采气速度,导致某些气井早期出水甚至水淹,低压气井和停产气井相应增多,气田的产量递减速度增大,采收率低,而且给开发工作带来很多困难。 In the past, for the development of carbonate gas fields, the production of some gas wells was relatively high due to the fixed capacity of wellheads when the reserves were unclear, and the gas recovery rate of gas wells in gas fields rose rapidly. Excessive gas production rate has led to the early water outflow or even flooding of some gas wells. Correspondingly, the low pressure gas wells and the shutdown gas wells have correspondingly increased. The output of gas fields has increased at a decreasing rate and the oil recovery rate has been low, which brings about many difficulties for development work.
