Abstract:

Karst weathering crust gas reservoir is a main type of carbonate gas reservoir,which is widely distributed in the Ordos,Tarimand Sichuan Basins.Due to the influence of formation water,the development of karst weathering crust typewater-bearing gas reservoir is facing a great challenge.This kind of gas reservoir is mainly characterized by large area distribution,multilayer gas bearing,thin reservoir,low abundance,strong heterogeneity,and big difference in gas well dynamic characteristics.The controlling factors of gas water distribution mainly include regional tectonic background,sufficient degree of gas source,small amplitude structure,the heterogeneity of reservoir,the distribution of the groove and the geological process of tectonic inversion and so on.The analysis of static and dynamic characteristics of drilled horizontal well in Gaoqiao shows that the main reason to cause the poor production effect is formation water.Aimed at their shortcomings and combined with their respective advantages of dynamic and static methods in the process to analyze the formation water distribution,the dynamic and static method was used to classify storage-permeability body for the first time.The reservoir is divided into high permeability without water,high permeability with condensate water,high permeability with sealed water,low permeability with sealed water,low permeability with condensate water and low permeability without water.At the same time,the distribution of all kinds of storage-permeability bodies is clearly exhibited on the plane.Based on the controlling factors of gas water distribution and storage-permeability body distribution characteristics,the development countermeasures of this kind of gas reservoir were proposed.This effectively guides the scientific and efficient development.

Key words: Weathering crust, Water bearing gas reservoir, Gas reservoir characteristics, Gas water control factors, Storage-permeable body classification, Development countermeasures
