Study On Optimization Of Low Press Low Production Wells And Intermittent Wells In Sulige Gas Field

Accroding to the static analysis of Intermittent wells’ bit distribution, structure location, reservoir properties and effect evaluation of fracturing, we try to find the static geologic factors influencing the production of intermittent well and low press low production wells.By studying the present Production dynamics and production system of intermittent wells and low press low production wells, the analysis of changes in formation pressure,single well controlled radius, dynamic reserves, recoverable reserves and gas well fluid situation etc. has been carried on and the dynamic factors which have a great affect on the production of intermittent well and low press low production wells.On the basis of optimization of gas well production system at home and abroad, geological evaluation and dynamic production analysis, production system of low-yielding low-pressure wells and Intermittent wells in Sulige gas field, Optimization study carried out for the well production system, to find the appropriate countermeasures for the well area production system to improve the well area mining economic benefits.On the foundation of the analysis of impact of gas well production of static and dynamic factors, classifying intermittent wells and low press low production wells scientifically, rationally to propose the related scientic, rational, completed production system of gas wells.By the combinated of geological evaluation,dynamic recognition, static recognition,the suitable production system, the comprehensive technology suited for low-yielding low-pressure wells and Intermittent wells in Sulige gas field. Under the Low-cost strategy, improving the wells utilization rate, the open wells rate and recovery overall.
