Development Methods And Well Adaptability Of Hu Lang Mao Area In Jing’an Reservoir

Low permeability reserves are rich,natural physical property is poor,difficult exploitation,exploitation degree is low. Reasonable well pattern and well network parameters can effectively improve the low permeability reservoir development effect, Reasonable well pattern has been a very crucial issue in oilfield development program,it is to ensure sustained oil production and oil companies to achieve economies of important technology. Development Well Network system is complex and dynamic sub-field development of the system,it consists of various single well together. Currently low permeability oilfield development well pattern optimization experience problems need to consider a compromise:geological characteristics and economic benefits from the development of oil fields of view, which is widely believed that only a smaller and larger well spacing well spacing density can achieve the desired development result,but it will lead to an increase the number of drilling, raise input costs.Therefore, study well pattern adaptability,selection of well pattern and well network parameters reasonably,become a key problem in low permeability reservoir is one of the effective and economic development.Use the jing’an Oilfield Hu Lang Mao areas Chang 6 well area of research and development wellblock as the research object and study applications laboratory experimental data and logging. logging a better understanding of the structural features of the Chang 6 well area, reservoir characteristics, fluid characteristics, reservoir typesand and the original drive pressure type; based on understanding of the regional geology and fluid characteristics. in the course of development of the well area as a reference to the oilfield development characteristics the development, and reservoir waterflood development effects to be evaluated:to more than two partsthe content is based on development scheme and wall pattern arrangement for Chang 6 well well network transformation before and after different forms of well network, well spacing density. And wellhead spacing rationality.
