Jingan Oilfield The 6 Section Reservoir Fracturing Optimization Technology And Application

Jing’an Oilfield Yanchang Formation producing layer is mainly characterized as ultra-low permeability, low pressure and low-yielding, fracturing operation is indispensable for the development of such oilfields transformation measures and has become a mature, supporting fracturing technology with good yield, in terms of the initial transformation of the reservoirSince fracturing operation has been applied in 1996, we focus on synchronize injection, local injection to achieve the first taken and make a timely complement to the formation energy, to inhibited the production decline effectively, and to achieve the efficient development of oil fields.However, with continuous development of the oil field, the impact of injected water, the original reservoir pressure, reservoir seepage law have obviously changed. In addition, the mining time, fines migration, congestion, heavy components condense fracture conductivity decline, the imbalance between injection and production wells also affect individual well production decline rapidly.Reservoir reconstruction technique is an effective means of stable oil production, which applies different modification techniques under different oilfield geological conditions. This paper analyzes several reservoirs layman rehabilitation measures, considering the geological structure, reservoir characteristics and development model of Jing’an Oilfield and proposes reservoir stimulation technology-reservoir fracturing for the development of Jing’an Oilfield. And we get the expected results through field practice, not only to achieve single well productivity improved, but to achieve the purpose of controlling the moisture content.Since 2002, oil production Plant Three has been implementing the duplicate wells transformation operations, the overall effect is significant. This paper sum up the effective transformation process to enhance the well production and success rate of repeatedly transformation of old wells with considering the storage of geological evaluation, production fracturing process and the evaluation of the fracture system.
